Nick worked with engines for 52 years before he got to work on a long ram intake.. now he has two in the shop. First it was the 413 and now this 440 torque beast is on the dyno. Here we GO!

I worked at the Chrysler Highland Park Engineering Center from 1966 to 1992 and ran a Performance Dyno. Up until 1975 the dyno operator was in the room with the engine where we ran power runs up to 6000 rpm. The power run lasted about an hour and there was no automated data acquisition. NO protection whatsoever except for a propshaft guard. What glorious days.
Good old days of no protection.
Did I get this straight ? You ran engines at six thousand for an hour ?
That's impressive
@@jesse75 NO. The power run took a little over an hour. Started at 1200 rpm and went up to 6000 rpm in 400 rpm intervals. At each speed we would set max spark advance for torque and then manually take all our readings including F/A mixture for all cylinders. Then we would go to the next RPM and repeat till we were done with the test. After the power part of the test we would run the engine out of gas and repeat all the speeds again recording the friction at each rpm and therefore know how much power was lost to friction. Then all the test readings would go to the engineer to calculate all the HP/Torque/Fuel consumption readings and then he would plot out a graph. Nowadays all that is done automatically with computers.
@@vietnamvet6726 interesting. So you had a way to spin the engine without it running.
I don’t know if people realize how fortunate we are that Nick makes these videos. This knowledge and experience would otherwise be lost forever. It’s video treasure.
Oh yeah 👍
That torque at that RPM is like diesel numbers. Amazing
It is a torque monster, but that Dyno pulls it down pretty good, Nick good job my man I love watching you. You are a true old school technician. We are fortunate to have you and able to learn so much from watching it and listening to you. Stay golden my man.
Not just a low rpm torque monster that's the coolest looking motor I've ever seen from any car company it's a bonus being a 440 Mopar totally badass Chrysler engineering and know how
I bet the guys that designed these old monsters had no clue that they would STILL be state-of-the-art 60-70 years later. God bless the Ramchargers and all the engineers at Chrysler.
And then on those long rams you’re right on there 440 Bighorn on the two front intakes
Interesting fact: The Porsche M28 V8 engine from the 928 cars had almost the exact same bore spacing as the 440 Mopar. Which means that with some drilling and welding, DOHC 4 valve heads could be fitted to this engine. Arias has done it with 502 Chevy big blocks; They use a belt cog attached to the water pump to run the four overhead camshafts.
A 32 valve 440 Dodge~?
Agree...back then the appearance of an engine was just as important as how it ran.
Impressive for sure!! That is the King of TPI long tube intakes!
@@Flies2FLL Used to live down the street from a place that made 4 valve chevy heads they woudltest their camaro late at night by my place. Neat stuff.
Watching that linkage twist from the top is like the coolest thing
It's been 57 years since I've seen a 413 with duel quads on a long runner manifold! This 440 with the duel quads and long runner manifold has been fantastic to watch today! Beautiful engine with a lot of muscle!
Amazing Torque , and the comfort of the Corinthian Leather , could You imagine the tv commercial for this if it was a factory set up back in the day 😂👍
Reech co-RIN-thee-an layther
@@_..-.._..-.._ Well spoken, Mr. Montalban . . .
Thank you Nick for reminding me of a older friend of mine who used to collect these kind of motors and the older Hemis and when he passed he left them all to me Thank you Steve Row hope you are RIP your friend Spud Grant!
Put those pieces to good use. My condolences 🙏🏽.
I have a 440 Magnum (out of a 1969 Chrysler Imperial) with this same Long Ram induction, crammed into my 1970 Dodge Dart. It’s super torquey.
Stock factory exhaust header that wraps up and over the steering shaft or something else
I always thought these Mopar engines with twin 4 barrel carburetors and the crazy long intake manifolds look awesome!
nick's team did a beautiful job on restoring this advanced engine. 550 ft/lbs shows the Chrysler engineers back in the day really knew their stuff. You are going to have to put 4 tires on the real axle to use it unless you don't mind changing out tires every 50 miles. That really is amazing Nick. , you created a beautiful monster. Your show is a master class in engine rebuilding.
We can't take the credit.. this engine was not built at Nick's. It came in for testing.
The Ramchargers drag team was Factory Engineers during the week.
Spending the tires will be an easy and fun task hehehe
Some of the readers here might enjoy knowing about THE SILVER BULLET- THE BEAST OF WOODWARD AVENUE. Type that into the search engine. It'll take you to the Plymouth GTX that Ford and GM like to pretend never existed. Yes, the Chrysler engineers really knew their stuff. They liked to play too. Hardball. Makes me laugh.
@@NicksGarage I know what you are saying because I can remember, the 1970 Cadillac Eldorado's 500cu made a whopping 400hp@4000rpm's and an even more impressive 560lbft @ 2700rpm's!!
Yeah, I know the brochure says 400hp@4400 and 550lbft@3000rpm's but 40yrs ago, my uncle told me that according to engine-test data-sheets and with that engine's extremely high torque curve so early, they could possibly reach 550lbft as early as 2300rpm and be over 560+lbft@2700rpm.
It's another Monday, and we have a long ram tube setup on the dyno, this time on a 440. I'm very anxious to see what kind of torque this engine can produce at 3000 RPM. I haven't see so many long ram intakes in a long time. It's like being back in the 60's again. You just never know what you will see on Nick's Garage. Let her rip Nick.
It never rains, but it pours! We are fortunate to see so many great things coming though the doors. Like your amazing Charger 500. Here we GO!
Should have started the test set at 1500 RPMs... or wherever the engine can take all 8 barrels... or 4 barrels if vacuum secondaries...
@@BuzzLOLOL You should have been paying attention to the video. Nick's dyno isn't capable of doing a test at 1500 RPM. The water brake is another factor for that hinders a low RPM test.
@@eugenecastles7475 - It's just a matter of setting the computer for 1500... at that low RPM or close to it the water brake may be able to hold the torque...
@@BuzzLOLOL I think if that were the case, Nick and Manny would have figured it out and done it. It is unfortunately beyond the capabilities of the Dyno he has. Nick had outright said this Dyno can not be set low enough to do it, and I think he would know.
Absolutely incredible. That is Efficiency at its finest right there.
This manifold is the original version, with the tuned ram tubes going all the way from the plenum under the carbs to the heads. They were tuned for peak torque at 2800 rpm. When they proved great on the street but not right for the drag strip, Chrysler then cast up some more of them, but with shorter runners (such as on the Chrysler 300-J ) that Nick just ran some dyno tests on. In the last 6 weeks Nick has been blessed with the "short-short" max wedge version tuned for 4400 rpm, with the "long-short" version tuned for 4400 rpm for the 300-J he's been working on, and now the "long-long" version tuned for 2800 rpm. Most MoPar vintage engine shops will never see even one of these manifold sets, much less all 3. Actually, many MoPar engine builders may not even be aware of them, because they go back to 1959-1964 and only we "old-timers" would have been exposed to them. Note that Nick normally starts his dyno pulls at 2500 rpms, but here he can't get a good reading under 3000 revs, the Superflow 902 dyno can't deal with that much low end torque. UPDATE: While watching this video the 2nd time around, I noticed that the aluminum heads were Edelbrock E-Street models, which are good heads, but not anything wild or special, so the engine is making HUGE torque with basically a close equivalent to stock heads. Also, I didn't catch it before, but Nick was saying these carbs were just 500 cfm each. Recall from the Max wedge test about a month ago, it had dual Carter / Edelbrock carbs of 750 cfm each, and Nick was commenting the 750s were too big. Maybe they'd even have allowed more power if they were just the 500 cfm units like this car has. Or maybe 600 cfm units. UPDATE #2: at the end of this video, Nick and Manny managed to trick the dyno a little bit more, and they came away with 569 lbs / ft of torque at 3000 rpms. Still, Nick entered on the computer to start the test at 2500 rpm, but the dyno just couldn't measure any HP or torque under 3000 rpm, no matter what they did. When looking at the power and torque curves on a graph, and working backwards, it looked to them that the final torque number at just under 3000 rpm was going to be 575 (!!) pounds / ft of torque.
Good information. Are these intake manifolds the same as the Max Wedge type? It is possible that many of these manifolds are on cloned cars?
@@markg7030 The Max Wedge intakes were quite different. They didn’t have long runners.
I believe that the only differences between the long and short runner intake manifolds were internal. Externally, they were the same.
Correct. @@MrJohnnyDistortion
@bobkonradi1027
And of course, one manifold was for low-end street torque, and the other was for the high bank oval.
I'm digging these cross Rams
Same here!
Wait till you have to work on it, changing spark plugs, etc. Also these things MUST be run with heat risers. I'm a 60 Plymouth guy and this was the OE option for the 60, yet I don't like it.
Loving them but changing valve cover gaskets will be a pain
Me too awesome 👍👍👍👍👍👍👍👍👍👍👍👍 👍👍👍👍👍👍👍😎😎😎😎😎😎
@@NicksGarage I would love to see one of these with a Mr. Gasket pro scoop on each one!
Pickup truck and C-body guys should all use these intakes. Wow. I'd sure like to see what would happen with a 540 stroker with this setup.
It would break his dyno!
Broken axles, u joints, twisted driveshaft, etc.
Imagine with a set of dual Holley Sniper EFI throttle body injection or Dominator EFI sequential multiport port fuel injection with twin 4bbl throttle bodies on a huge stroker.
This concept would be interesting on a small block road racing engine.
@@hendo337 that would be the way to go with this type of intake manifold. You could see in the beginning how they had to spend extra time getting the engine warmed up as the shape of the manifolds and lack of heat to the carburetor plenums made it difficult to get the fuel atomization stabilized. Fuel injection would solve that issue and is why you see long-branch tuned intake manifolds on all modern EFI engines.
My grampa had this engine in his car and one night while drinking in Kenosha Wisconsin he was heading back to Illinois when the police attempted to make a traffic stop! Well being the good ol boy he was he floored it leaving the officer in the dust! Knowing he was heading for the state line Kenosha police radioed to the Winthrop Harbor Police stating they need help with a car flying their direction! Well gramps tore the gears out of his transmission near the state line and coasted into Illinois! As expected the police were a waiting and watched as the car rolled into town! The officer pulled up behind him parked on the side of the road and said we’ve been hearing about a hot car evading the boys across the border and honestly this car couldn’t outrun me on foot! The officer gave gramps a ride home to get his truck and actually followed him to make sure he got the car home safely! Things sure have changed!
Gotta love Manny he's Nick right hand man..
I am close to 76yrs. Old. This is my first time seeing the long ram. They are very impressive. Thank you very much. I really enjoy all of your segments.
Glad you enjoyed it!
Thank you Nick! The 440 line is legendary. This is a perfect example of why a stock 440 can always blow minds. With nothing else than a carb mod , you got everything from a tractor to a rocket. It's no wonder Chrysler had space program contracts back in the day.
The engineers knew what they needed to do to get a heavy axxed car moving! It was the ultimate design for performance to rapidly move a 5,000+lb car!! And then they built the ultimate balance between vehicle weight and engine performance....."the 426 Hemi"!!!
Maybe not really understanding at the time, but what a memory to have to have lived through that time period! Yep...I am old. (But I am blessed!!) I've forgotten more than I remember!
Thanks for the memories Nick!!
Thanks George! I noticed the lights!! It's nice to have options! Just got here and ready to see the dyno results on this 440! So cool!
Haha! Glad you caught that.🌈
The infamous Helmholtz effect. It actually works and works well. German four and six cylinder engines started doing this in the 1960's to great effect.
What is happening is that the charge rushes through the long tube, gaining speed. When it hits the closed intake valve, it bounces back and hits the charge coming from the carburetor, then bounces back again toward the intake valve. It hits the now open valve at exactly the right time at low RPM, essentially supercharging the engine. Volumetric efficiency can reach nearly 100 percent when this is done right. Long narrow tubes are good for low RPM cylinder filling, while short fat ones are good for high RPM.
Applied in the slant six manifold
@@brownwrench Perfect example.
Great knowledge to know. Thanks.
When I saw the thumbnail for this video I immediately checked the runners to see if they were the long "long" ram manifolds like Nick said on the short long rams. Just like he said they were. I love these dyno vids, 569 lbs torque at 3, grand?! Talk about being able to pass school buses quickly!
That engine is a tire shredder no matter what car it goes into. WOW! Very cool Nick, Manny and George. Thanks for sharing this beast with us. Stay safe all, God Bless.
Very interesting design, I remember when my dad had his 1962 - 300-H convertible, what a great car
My dad had a 70 polara police interceptor I can still remember the distinct sound that 440 had I believe it was 150 on speedo and we buried it on night .loved that big old boat my dad ran my 68 ss 396 4spd camaro373 posi my old man past me at probly 60' and walked off and left me probly 4 lengths for the win ..rip papa coy.b29 tail gunner hats of to the greatest generation bless u all.
Brings back memories… I put a cross ram induction system with twin four barrel carbs on my ‘69 Charger back in the day… I could drop to 2nd gear at 55 mph and lay a streak of rubber on the interstate.
Would love to have a set up like this in a earlyy 70's power wagon tow rig
Mopar engineers weren't afraid of pushing the limits of understanding and building off of what they learned to make some outstanding pieces of mechanical genius and art!
Man oh man!!!!! Nearly 600 lb-ft of torque around 3000-ish, this’ll give the 455 Buick fits!!!! These long ram manifolds could become a hot trend among the classic Mopar crowd if this keeps up: wonder how many other guys still work with them. George, if you would, ask Nick and Manny if they could give a short explanation of how a dyno does what it does. Thanks for another fantastic video session at Nick’s garage!!!!
Basically a water brake. To know power, you need to know the load, so it's just a water pump that measures volumetric flow.
Don't forget, that torque number is "net" not "gross" and working backwards from 3000 rpm, the dyno graph was climbing back towards 575 lbs / ft torque at 27-2800 rpm. Absolutely incredible. Do we realize that this engine, in the man's Cordoba (with its Corinthian leather seats) in a 60-80 or 6-0-85 mph car passing race with a Corvette , the Corinthian leather would get there first.
Really. I don't think Buicks had long ram manifold and 2! Carbs to make beastly torque
@mistersecret88
The Buick & Pontiac 455 engines were underrated at 525 ft/lb of torque. Buick heads had great flow, were known Hemi Killers and the Buick 455 is only 50lbs heavier than a Chevrolet 350.
We all love different manufacturers but we all love horsepower! Great video!
Mopar or no car.
Love that dancing clamp roaming around
That thing is gorgeous. The old school 440 with that exotic long ram dual 4 set up is magic. Then the full modern accessory package is the the perfect combination for the Cordoba to be the ultimate luxury look, nightmare.👏👏👏👍
Great show Nick, really enjoyed this one. I built a 440 in a 1975 New Yorker again the 440 was a torgue monster. Spent my mechanical youth money on the Direct Connection Catalogue.
A great way to start my evening.
Hope you have a great one, Mooseman.
A long ram and Corinthian leather! Great combo! It is great to see folks are now giving Cordoba's some love!👍
That's why in the '60s when I grew up my dad went out and started the car half hour before we left anywhere in the winter here in Michigan
Those were the days.
Amazing, all that torque without a stroker, the long ram is awesome and all without nitrous, supercharger, blower. Naturally aspirated
And at low RPM!
Just imagine a 100shot or a blower on this! Anyone know of a project like that that's even been tackled?
I mean, it’s still a gigantic displacement. Even without any mods, it should make great torque.
Some of the best classic vehicle engines known from Chrysler and they are always at Nick's Garage.😊
May need a Tractor or Truck Dyno for this application.
They operate at lower RPM.
🙂
Nice job Nick.
Thanks for sharing.
Take care, Ed.
There is nothing better than a Mopar that has the expertise of Nick's Garage to get dialed in. Canada 🍁 has a real gem! This engine looks like a boxer in a three piece suit.
Look at Nick getting excited, he's seen so much in his life time that it takes a lot to excite him and that excites me. At our age he and i together have seen MORE than most yet not as much as others. It does do the old SOULS JUSTICE to receive comprehension at this level. Thanks too all the above.
this is what i call an engine with class. it does just what it is supposed to do . good work Nick your the best.
I love it! My brother had that on a 440 in a short bed 73 D 100. It was awesome!!😊
Awesome! Dads 1964 plymouth fury, borg t-10, 5.13 gears cheater slicks. 1959 413 with long rams, big cam. Broke a bellhousing at 7500 rpm. Took trophy home hp/ci class at bunker hill dragstrip in Indiana in the 60's against 427s 426s all in the class. Fast forward to the 1990"s my green 1970 newport named "Marge" 8.2:1 440, 4:10 gears experimental cam 7 in of vacuum. front wheels up high leaving in 2nd on full manual 727! Blew thru the 6500 rev limiter. Now on a 400 in a 1968 monaco 4.56 gears More to come with a 413 long ram in a dragster.... I can't complement you enough, Nick!
Gotta tell you Nick, this episode was SUPER interesting, thanks.
What a beast of a motor💪. As usual Nick and crew always bring the best content. Best show on utube.
You've done well setting up the carbs so there is virtually zero bog. 👌👌👌👌
Had a '72 Chrysler New Yorker Sleeper with this intake setup... 4-6 MPG City 11MPG Highway on 98 leaded octane.
it used to eat corvettes for breakfast! Never forget the sound of the 2 carbs @WOT
When I was a kid our neighbor had a Dodge. He would tape a $5 to the dash and say, "When I hit the gas...if you can grab that, it's yours to keep". I don't think anyone ever got that five spot. My early introduction to torque.
Just goes to show you, Chrysler Engineer's had an awesome idea! Torque is king, horsepower is only a "top end" thing. I maybe a Ford person, but Mopar still is the bomb!
What a lot of people don’t realize is that horsepower is the derivative (calculus) of torque. So, engine configuration to optimize torque somewhere on the RPM range obviously influences horsepower, but horsepower is not its own separate thing.
It’s like the confusion of centripetal force and centrifugal force (the latter is just inertia restrained by centripetal force).
So the more effective way to describe engine performance is to compare the torque curve and consider horsepower less as a unique number, but a measure of how rapidly torque increases or decreases over the RPM range.
Im a ford person, i will never turn my back on the brand i trust, but i can say i like all muscle cars, i just have a preference that's all
What a lot of people don’t realize is that torque is just a rotational force. Horsepower is literally work done over time.
Torque breaks parts like driveshafts, and transmission, as well as traction; horsepower is one of the variables you need in a quarter mile calculator.
This is why everyone with a fast car (myself included) fears the guy in an EG civic with a turbo. That’s because 550lb-ft at 3000rpm is still just 317hp, and in the Civic 300lb ft at 8000 rpm’s is 450hp.
The Civix wins this because it makes nearly 400hp per ton and the Cordoba would only be making 220hp per ton.
The fact that the Cordoba makes 350lb-ft per ton and the civic makes 250lb-ft per ton had nothing to do with it.
Talk about a torque monster!
Beast mode!
Greetings from Greece Niko ,I'm an Greek, Aussie also a Engineer M.A.N trucks,busses !
I tried exactly what you"re trying to do; install a RB w/long ram into the last b-body generation. I bought a 28K mile loaded 1979 Chrysler Cordoba Brougham back in 85. It had the anemic 318 lean burn, 904 & 8 ¼ rear. Took me 9 months to built her the Right way. 512 cu based off a 440. 12.5:1 comp, I also hogged out & ported a set of 906 heads on my homemade flow bench (built from a 3 part article in Car Craft back then, along with a 727 HEMI trans, Fairbanks reverse man trans, 3200 stall, 8 ¾ w. 4.10, adjus.....you know where this is going. The list of parts was long but the car looked bone stock. She put out 585 HP to the rear wheels and 471 lb/ft of torque.
Suffice it to say that the original power booster, master cyl. & fender braces had to get gone. We installed an Wilwood reverse throw brake set-up off my buddy's dirt track car under the dash to take her out for her maiden run. She screamed and got loose going into 3rd. With all that GO the Wilwood set-up was too weak; which really surprised me. I ended up getting my money back on the long ram; luckily the guy was nice enough to undo the sale; which was only 3 days old. Ended up going with a 1000cfm ThermoQuad on a shaved Team G intake. She had quite a short life but for the year I had her; it was awesome.
The 1970 Buick for 455 stage one had about 500 foot pound torque a little over 400 hp. It was the ultimate sleeper with the right wheels you got that car in the high 12s that’s what this reminds me off.
Amazing numbers! Oh my goodness I remember it was the 70s Ricardo Montalban came on TV advertising Cordoba with its Corinthian leather my mom and dad both fell in love 1976 there was a brand new one in the yard the old man just had to have it Mom just loved it what a childhood memory right there⛽️🇺🇸
"Rich, Corinthian leather."
Nick, I just wanted to say I love your videos. I dont restore cars anymore but man I love when you fix / teardown /dyno engines. FYI...In 1978 I was 18 years old and my second car ever was a 1970 Dodge Challenger R/T with the 383 Magnum. Slapstick automatic. LOVED that car. Please keep making these videos !!!
Nick, I never thought you would say TOO MUCH TORQUE! . Awesome show!!!
Thanks for watching!
Props to Nick for going the extra mile and making a period-correct Mopar commercial with himself as the star.
10:00 Your Dyno is different than our SuperFlow, we have a separate ball valve besides the absorber adjuster valve, which you can use to put additional water into the absorber. I've had a few lower RPM big blocks over the years that I needed to open that valve to "capture" the engine for lower RPM tests. Most common are the 502/540 BBC's for marine applications.
My father always tells me about the intake sound his 300s made with the banana tubes. Nothing else like it.
What an amazing project. That was so cool
Thank you
👍👍👍👍
Herb Tarlek aways loved the Cordoba 🙂 👍
And Jennifer.
It was Mr Carlson who drove a Cordoba
Anyone need any old stumps pulling out? 😁 Thanks Nick, George and Manny!! What a monster with long rams it is.
Hot Heads! They sent us (Chrysler JTE) a 354 Hemi with 555 heads with only 18,000 miles for prototyping analysis for the Gen III Hemi. Running it on port fuel injection, and a stock JTEC engine controller, it made 385hp. 40hp more than the 5.9L Magnum premium fuel tune right out of the box. Hot Heads are the BOMB!
I’m just here thinking about that Engine going into a ‘77 Chrysler Cordoba , the one with “The rich Corinthian Leather” . I remember watching an episode I believe of Saturday night Live , where Ricardo and Tattoo were doing a parody of Fantasy Island , where Ricardo said he wanted Tattoo to “ Get into that Cordoba , and drive it over the cliff into the ocean” , to which Tattoo replied ,” But boss, I’ll be killed “ !! Ricardo gets a knowing smile across his face & responds “ Well, that’s MY fantasy Tattoo”😆👍. Cannot get away with that kind of off candid humor anymore these days unfortunately. Great engine build by the way . Thanks for posting this one 👍
That engine is a BEAST! Thanks for sharing it with us!!
This Long Ram induction really is a work of art and this engine would literally pull houses down with its massive tyre frying torque!
Great video of an epic Mopar big block 👍
Back in 1978 I had a 71 Swinger with a 440 and these manifolds. I used two AFBs 500s and hooker fenderwells. Had to remove the casting for the water heating to fit over the shock towers. Incredible watching you guys drooling over the torque. Yep torque was king and no RPM needed. Actually at 4500 RPM it would start to lean out. I worked for a Chrysler dealer and another older mechanic had a '63 Chrysler 300J with the original crossram on a 413. That 6000 lb car would cruise and pass anything. I sure wish I had my Dart back again. Drove it winters and summers up here in Canada and ran the AC in the summer.
Getting in there to choke the carbs by hand to get the thing warmed up is some dedication. That thing is a BEAST
Awesome Engine buid , when I had my 1970 455 buick stage 1 made it a 462 what a torque monster
Thanks Nick! Super fun build. Got to love these torque monsters. I had a 1970 eldorado convertible with the 500cid. Same thing. 535 ft lbs of torque. Could get a little wild with the front wheel drive.
The 500 in the 70 Eldo was rated at 550 lb. ft. torque to go with 400 HP. Those are gross figures.
BY FAR the most beautiful engine EVER made.
Love your channel. The enthusiasm and vast knowledge you have is extraordinary, no computers here, listening, seeing and feeling. Experiece, Here we go !
That 440 has so much torque, probably the only tires that won't spin would be the proper size slicks. The only thing is you wouldn't be able to drive in on the street. What a BEAST!
Another build that I've been wanting to see. A 440 with ram induction system!
Thanks for waiting!
Somebody, somewhere who has access to mold makers and casting facilities needs to make up some more of these manifolds. Both the standard version (as this one is) and the hi-po version as per the 300-J that he's also working on.
@@bobkonradi1027, a guy with a tubing bender could weld up a set.

My dad used to have a 67 Charger that had a 440 Magnum. It didn't have this kind of intake (he's always called it a cross-ram intake), but he did have a Holley 700 and a purple stripe cam, and managed to beat a Corvette going uphill with it.
Buddy in high school had a 72 D100 1/2 ton in the factory yellow. Just a touch of natural patina, but no rust other than surface. He had a built 440 with header mufflers and an A727 with a decent shift kit and a high stall converter, something like 2500rpm. I think he had an 850 or 900 cfm Holley on it. The torque that thing made... It turned the earth beneath the truck. He couldn't keep tires on that bastard. In the summer it was absurdly hot due to those header mufflers. It would clear the leaves out of the gutter if he parked it on the street. What a fantastic truck, and a fantastic motor.
I've toyed with the thought of simply putting a 5.9 Magnum into an early 80's Cordoba along with the A518 and the 3.55 axle from a Ram. My folks had a 1980 and I loved that car.
Great show today Nick and George, and I always love Manny’s input! 🚗 💨
i have heard of ball breaking but this takes it to a whole new meaning
In automotives class, way back in the early 1970's, we only ever saw these engines in manuals. Great to finally see examples of Chryslers hard work
Nick says, I did it with a small block, the Dyno tech says Nick, Nick, this is a STUMP puller. Lol. 😅😅😅
Gives new meaning to the word 'serpentine.' What a cool looking engine.
Ssssssss
Jet boat pumps are very similar to dyno’s, there’s a jet boater that put a Cummins in and had to add a transmission. He added the transmission to get his shaft speed up. I wonder if adding a manual transmission to let the motor eat and get more shaft speed to make the dyno happy would make more measurable results
My project car was a 1979 Chrysler Cordoba, with a 440 bored 30 over and balanced to zero. Slapped a Holley 4 barrel 1000 cfm throttle body fuel injection on it, back in the early 90's. Car frame rotted out from the inside and didn't have the funds to replace it. Wanted to go full frame from the unibody to keep it from twisting the car in half. It was running a dual plane intake, which matched the cam rpm range, theoretical numbers were 401 hp at 5200 and 450flbstq at around 3800, theoretical as I've never got a chance to get it dyno'd. The numbers were from a cam profile software based on cam specs and a 4 bbl carb on a dual plane manifold. I miss driving "The Beast", still have it but it's just rotting away in the driveway, don't have funding to do what I want, but glad I made a video of it when it was driving, from time to time I'll look at the video, it always puts a smile on my face.
This video brings me back to when I was working on it. I can't work on cars anymore as it does take a toll on my back and I end up walking beside myself, literally. "The Beast" was temperamental as it didn't like to start when someone other than myself or my brother tried to start it, which made it difficult for our service station guys to do inspections on it, lol, "The Beast" as we called it had a personality, it loved being showed off at car shows. It's been 27 years since it last ran.
My parents had a '76 Cordoba with the 360 2-barrel. I was looking up the biggest engine option which was the 400 4-barrel, and it "only" had ~320 ft-lb!!! While the Cordoba was fairly heavy, the Imperial could really have used this setup given it was 1500 lbs heavier.
Another great show you guys made my monday thank you
The torque at these low RPM's is amazing. The difference between the 4 barrel and the dual long ram is also amazing at the differenced in amount of torque and at what RPM. I never knew they made the two different long rams with a different RPM at which they worked best. They knew how to make those big cars get away from a stop for sure.
That was so fun to watch Nick! Thank you!
Good looking engine.
“Rich Corinthian leather..” ‘75 Cordoba with that engine I like Mark’s thinking.
We ran a '69 383 (from a wrecked "69 Charger in the Netherlans, so unique) with the intake manifold totally ripped out, just an Edelbrock (Weber) carburettor (original Holley card was crep) of a 383 Road runner (probably "67) and it was in third gear, flat out and burning rubber till 90 Mph and screaming until 6300rpm (OK, valve springs shimmed). We had some higher compression pistons in it, but was fun to race. We had 9 years "full throttle fun" when the dirt car was sold. Long induction was unknown here in the Netherlands , but man oh man, we burned rubber🤣
Back in 61 a friend bought a New Plymouth Savoy post less coupe in a beautiful blue, with the CrossRam option, Torqueflite and 3.23 gears. His car looked very very cool. But the Ram Sonic stole the show. I had a ugly 61 ford fairlane coupe with post, , 390cid, 375 HP, three on the tree with 4.11 gears. I smoked him with ease.
I'm a long time Mopar guy, but I sure learn a lot on Nick's videos. I never knew the difference between the two long rams, the 413, and the 440 ram seen here.
Thanks! We are learning too.
Hi Nick, John from the U.K. are all your dyno runs done in SAE net? I’m wondering if you could explain the difference between gross and net HP please?
@@johnchurch4705 He explained early in the video that he normally tests gross HP with no accessories, no air filter and an electric motor driving the water pump so the engine is not even doing that. This engine came with all the accessories in place, so this test is net HP as installed in the car with accessories.
@@johnchurch4705 SAE (Society of Automotive Engineers) Gross HP is the engine running without the accessories dragging down the engine. Note that Nick normally runs his engines with an electric motor on the water pump and with no accessories such as PS, alternator, air conditioner, etc.. With the accessories hooked up and dragging down the engine, it is DIN (Deutsche Industrie Norm) Net.
the ram shown here was also 413 never on a 426 or 440
I put a 413 2x4 long ram engine in my sisters 1976 Charger. Trashed the 400. Car ran high 12's at the drag strip in Killeen Tx. Back in the early 80's. She wanted to go faster!
Torque is KING on the street. Not only for heavy cars. Always biased engines towards torque vs hp above 3 litres. Never regretted it. Like Nick himself says "With this much torque who cares about horse power" Just make sure your drive line is sorted as a torque monster will eat pretenders
That engine sounds SO MEAN!!! Love it! Good job, guys.
Thanks!
