My uncle was a Mopar guy his whole life. He always had an old roadrunner or other old Mopar's and spent his life working on them. He would have loved Uncle Tony's channel. RIP Uncle Butch.
Something interesting that we found out on our Hellcat build. The exhaust port spacing is the same on a gen3 hemi and a 331-392 head. So we took 1st gen hemi block hugger headers and made them fit our hellcat.
Believe poly 318 exhaust were same also.
In 1999 I pulled a friend of mine away from Fords and got him interested in Hemis, ever since he blamed me for his financial ruin. He developed a major interest in the gen 1 Hemis and bought every basket case he could get his hands on. He started Vintage V8's specializing in custom high rise manifolds 4 barrel manifolds he designed and he worked closely with Hot Heads out of North Carolina. He built some nice Hemis and was working on a muli stack fuel injection install on his 331 Chrysler when he suddenly passed away. We were dedicated motor heads, he was my car show budy and a damn good mechanical engineer. I miss him a lot. Thanks for a really great channel Tony. As a Mopar guy from all the way back to the 60's this is really enjoyable.
Tony, every time you do an engine video I can tell this is your passion, I always come away loving engines more at the end
Dennis Taylor ("riding with Alex Taylor" father) just tore down his old gasser 331 and showed the girdle and mains he fabricated. He made his own main caps and did a cross bolt like the ford side oiler to tie into the girdle ring around the pan.
Dennis is tonys brother from another mother....but they never met
I watched that video , I thought he said it was a 392 . But either way it was interesting to see an aluminum Donovan main assembly on an iron block.
LA timing sets can be used on FirePower hemis as well.
I remember guts call early hemi's flatheads and could never figure out why. Seeing that block & the pushrod holes answered all my questions!
Thought you were a couple or few years early with the Mystery Motor, so I looked it up, and they're saying 1963 - and JUNIOR JOHNSON!
Man I love your history and engineering videos
In 1974, my father and I went to see a man who was parting out an old, Dodge dump truck. We bought the engine and trans. from him for $300.
It was a 392 hemi w/1 ton four speed. (I don't think he knew what he had but, my dad a dad sure did).
We tore that engine down and had it spread across the garage floor. We rebuilt/replaced everything needed, had the block and heads worked and put it back together, that was when I learned to overcome my fears of mechanics/rebuilding and is a lesson I just went through with my (now adult) son as I asked him "What if we put it together and it doesn't work?" to which he replied "then you take it apart, figure out what the problem is and start again, dont be afraid to fail." It doesn't get more straight forward than that and was how I ended up an career ASE tech.
After the rebuild, we put the engine in a 1962 Dodge, D100 pickup (classic, beautiful truck but, this one was an old workhorse, a couple different colors (yellow inside the bad and the classic blue outside) and dried concrete remnants in the bed, etc., solid, not dented up but used and an "ugly duckling." It also had a two speed rear end.
When it was all together, it wouldn't crank because it was so tight so we towed it down the street and dumped the clutch to fire it up but it breathed fire and came to life. That combo of a 392 + 1 ton tranny + two speed rear end was w working menace. 😊
Dad had some "buddies" (bar and the hunting club we belonged to) and they ran their cars/trucks at the local strip on the weekends. They had their new, square bodies with "hot" 350s and the like and one guy had "the truck to beat." Dad watched him foe a while, then said "I bet that ol', beat-up Dodge will beat your new chevy." The race was on.
When they took off, the other truck got the immediate jump but our Dodge squatted, grunted and lifted the right front tire off the ground... He ate that chevy for lunch. 😊😂
The other guy was pissed, everyone else was amazed but nobody got to look under the hood of our truck. "Beat it and you can look." said dad and that was it. 😊
That gen 1 392 wasn't made foe a lot of revs and high end HP but, it made a shit ton of bottom torque and decent top end for an 1/8 mile, especially with the high fourth and 2spd rear. A deadly combo, for sure!
I now have a '22 Challenger Scat Pack, Shaker edition with the gen 3, 392 w/tremec 6spd and it's a beast. Very different, yet similar in a lot of ways, especially the HP/torque dept. 😊
I traded my 331 to my Snap-On dealer for a bunch of tools I needed but, I still have my *240 Red Ram* in the shop. 😉
My father was born in the mid forties and was always green with envy cause in the rural area the farmers had money and some had the big motor dodge and Plymouths he did not have that kind of green he was helping is mother raise his younger sister and sent alot of his money home he did get a 72 galaxy 500 with 4w9 police
Intercepter motor that car was powerful it was a heavy car and its top end was triple digit 130 plus mph easily and because of his teachings I had the odd speeding ticket as well I think he still has a love for the big motor Chrysler products .
Awesome history lesson start to finish
Appreciated
I really appreciate that when you get deep into the minutia of engines but especially the hemi … your voice gets higher. You talk noticeably faster. And you’re smiling more !! There’s no way someone.. anyone … couldn’t appreciate your affinity and knowledge !! Never said this but I’m 53 and remember going to the Dodge dealership and walking into the shop with my dad and he went over to the station of this older guy and knew him by name and he showed my dad how to do whatever it was. I asked why and he said the ( time specific for the time ) just go talk to the guy that’s been it the longest ! In anything you do or have questions about he’s gonna have the most answers and help you figure it out ! I was maybe 10 !!!
Excellent video. Information was very well explained, easy to understand and with the side-by-side comparison of the two engines, even a person of limited mechanical skills and experience could comprehend the concepts. Well done.
No Stellantis content.
Big thumbs up 👍
I think that 392 with high compression running on propane would make a good engine for power and economy.
13:28 I first saw this photo when I was a kid in the 80s, either in a book or Hot Rod or something, and it was as mesmerizing and brilliant to me then as it is now. Everything about this photo is near perfect.
Wow, I never thought about that cam torsional flex, horking the ignition timing for all eight cylinders because of the rear-mounted distributor. It also throws off the valve timing, progressively, all the way back to the rear two cylinders.
Great history!
HotRod had a good article a few years ago about the troubles Don Garlits had transitioning from the 392 to the 426.
Big Daddy did more for the Hemis than anyone else in drag racing, IMHO.
@@elmerfudpucker3204 I had to do a double take when I saw your name….My Dad’s name was Elmer and my aunt called him Fudd.
Great stuff ! Good luck at the track !
Super cool video, Professor Anthony rides again! I love it when we get these deep dives into Mopar history 😎
Great information. Good luck at the races tonight, let’s see what the XJ can do!😁💪
I have a 58D 392 hemi. It came from Bob Sullivan "Pandemonium" from Kansas City
My favorite videos are this type. I appreciate learning from your experience and knowledge pool
Just got done a week of fixing “modern cars”
I’m ready for a smoke and some uncle Tony ❤
Love y brother man.
You’re part of the reason I have a good attitude and am still in automotive industry.
🥝✔️ Nicely summarised.Mouse SBC, Rat BBC..lol. Mopar..." I'll tear these Meaces to Pieces..."
The rodent won in the end. Still around. But old dodge engines do be cool as hell
I love it when you explain the architecture of these engines. You make it so easy to understand. Thank you,Tony.
It'll be interesting to watch the progression on mission improbable. I had a friend that had jeep just like that one. I was amazed at the balls that thing had and often wondered what it would run in the 1/4 with a set of decent tires.
Really appreciate this type of content. Great video 🤘🏼
Modern 500cid Top Fuel Hemi's have 4-3/16" bores (4.1875") and 4-1/2" strokes (4.5000"). This combination yields 495.7949cid actual displacement. These engines are estimated to produce 11,000 horsepower. Yes, 11,000hp estimated because no dynamometer can withhold that level of torque. All this with the factory 2-3/4" (2.7500") main bearing journal diameters. Chrysler Firepower. Properly named.
And, Nascar V8's have nearly identical cylinder bores (at 4.1850") with much shorter 3-1/4" (3.2500") stroke length. Excellence runs deeper with the engineering done in the early 1950's...
Other engines that share the 4-3/16" cylinder bores...430cid Big Block Buick. 413cid RB Chrysler. That's about it...until the new 5.5L Chevy flat plane V8...it claims a cylinder bore diameter of 106-1/4mm (106.25mm) which is 4.1830" diameter...some things are just right, and time proven. No improvements can be made...even if you are "woke".
1 word, EXCELLENT!
Kinda great ut refreshed our memories of the past..skip gen3 ut nobody cares. Well i don't
When it comes to Hemi's and their inner workings--you've come to the right channel!😎
Mmmmm, 1st generation Hemi.. Drooooool....
thanks for sharing all this information ❤
Thanks for the history lesson UT
Enjoy them teenage style gear changes at the drag strip tonight 👌
He looked so happy talking about Hemis
392 is being built soon?looks like new cam bearings in there.
The hemi motor is still being used in top fuel and funny car racers it is not factory but still based on the factory motor.
4.7 semi hemi ???
I thought that today’s Top Fuel motors were based on the 392. I guess I was wrong. Thanks for the content Tony.
I like history.Too bad it's being re-
Written
I appreciate your knowledge on th9is Mopar stuff Tony. Thanks. Just curious, have you ever watched "Nicks Garage", he's in Canada. He is a Mopar guru too.
Cool video, I've never owned any hemi. I like the evolution of things type videos , nice to see where they came from.
392 with navigation n 8 speed automatic superior in every way even dodge agrees thats why they have them in dealers.
Uncle Tony you are a wealth of knowledge
Great tech and show and tell.
I spent some time studying engine tooling and manufacturing techniques. It is really amazing how tooling and production considerations have influenced engines over the years.
The lifter bank angle was carried over because the broaches to do the cam tunnel and lifter bores are complex, expensive pieces of equipment that were produced contractually for the OEM, in this case Chrysler. They might have had a 3 or 5 year contract on the tooling, and as new engines were designed a lot of consideration was given to things like production. Details like bore spacing, lifter placement, even mounts would be carried over so extant tooling could continue to be used.
The same applied to manufacturing tooling for cylinder heads. There were two companies marketing a complete cylinder head manufacturing package in the 1950s. Their design had certain requirements in the castings. That's why heads for a Cadillac, Packard, Olds, and Pontiac look similar on the outside. The other company supplied Buick, Chevy, and Chrysler for the B/RB. The tooling for those heads originated in a design Buick was working on, but dropped in favor of another design. That was eventually picked up by Chevy, and went into production as the small block. Chevy was working on a family of engines they dropped, that Buick picked up and revised to eventually become the 215, small block Buick, and v6 engines. If you look at the manufacturing requirements of the heads in these Buicks, the small block Chevy, and the Mopar B, it becomes clear they were intended to be manufactured on tooling of a similar configuration.
Thanks for the video.
Thanks
COOP
...
Almost can’t wait for the Bowtie Lineage tutorial from The UnCle that respects it deep down .👊🏼⛽️
So the hemi's nicknames are like the n-word for mopar guys...
Thanks Uncle Tony!
Haven't been this early since my last child was conceived
And again thank you Tony for the history lesson very interesting thank you Sir
Love early hemis. I run a 392 in a 1933 dodge coupe.
Very interesting content! 👍🇺🇸👍🇺🇸👍🇺🇸
Good video! Glad to see Tony building a couple more hemis after hearing him say not long ago that he had no interest in ever building another one. Hope that 426 finds it's way into Slaghammer.
Very interesting and entertaining, too. I think you were hinting at a video on nitromethane motors, looking forward to that.
I'm surprised that the upper half of the 426 mains is a problem...do they really Crack there? Doesn't seem like much force applied in that direction.
Thanks for your videos.
Outstanding !
So what you're saying is you could put a first gen 392 Hemi into a 340 Duster, Demon A-body chassis? Engine mounts too?
Tony Peperoni..always on fire
The gen 3 hemi was designed by Ricardo engineering. I worked for awhile, for the gent who was the liaison between companies.
thanks Uncle Tony. great 👍 video , great information for many years never known about this before well ☝️👍👍👍
Tony love your history lesson videos. You could be the next Alain de Cadenet . But instead of Victory by Design it could be called Victory by Desperation. Keep up the good work 👍
Hemi's forever!
Thanks.
XLNT vid, Cheers .
Have fun at the track tonight.
I look forward to hearing and watching how you did.
I'm getting ready for the 5.7 hemi knock soon. 😅😅
Hello.
If It's got a smaller bore than 4" . Count me out! I make an acception for working on 4 cylinders, One Ford twincam I worked on was 86mm and that was cool, you really cant have good valve area with an engine above that, unless its a 4 valve design. I was going to do a 454 with a 409 crank to get a 400 cube motor with the valve area of a BBC, I still might do it
Man I love your history
Early Comment!!
With the current Hemi''s I was wondering why thy couldn't make a bridgebar style setup to turn them into a 4 valve - like the 6.7 Cummins have. I'm sure they could have done a ton more to make them meet emissions personally.
great video U.T....u can never know too much..!..when ever a guy work'd as a line mechanic or forman @ a dealer...the info that was avable to them was endless.!..that is "if" they were into what they were doing..add a drag racer to the mix...&..."poof"...Uncle Tony...!...😉
U T. G thanks for explaining that the only dodge I have had was a slant six my brother had a Plymouth with a 383 4 barrel 4 speed in a raged out veer it would eat new Ford's and chevy for lunch.i like it when they say what ever.brand they talk about in cubic inches not like 5.0 5.7 just cubic inch.like you do.Thanks.😊
Yeah the Mopar engineers really screwed the pooch handicapping the big block wedges with the small block designed heads, which is pretty much the reason why you can't get anywhere near as much h.p. compared to a big block Chevy.
Love the history! Thank you Unko!
The 1st gen has different dowels and bottom bell bolts.
Needs an adapter to bolt to a small block trans
Tony ive got a question about rod studs on a 351w. Can you put new oem ones in without resizing rods. Just plain old stock replacements. I was torquing them and a few didnt feel right. Its just a stock rebuild. I ordered a nos box of pioneer studs. Figure do them all. Thoughts????
Hey Tony i love all your content I really do ,it doesn’t get any better lots of respect of your knowledge I’m in the trades myself carpenter , but sounds like you don’t like the 3 gen hemi 5.7 , 6.1 , 6.4 I have a 2018 challenger 392 , if you have the time could you give your thoughts on these engines ? Thanks bud
Quick question, are the early Hemi's "Internal or external" balanced?
Good stuff as always Uncle Tony.
Gen 3 hemis are grasshoppers lifters and needle bearings flying around everywhere
My father's old time best friend in the 70's had literally every special equipped mopar you could order.
He had anything from R/T to 6 packs to Hemi cars.
His father owned a junk yard and got everything he wanted,so Mopar was his choice.
He never kept a 1 because he totalled every single one.
Live your Mopar knowledge. Thanks for sharing.
Where were the Chrysler Firepower engines cast/machines/assembled? The best I can tell is they were assembled at the old Jefferson plant on the Detroit River side of the street. Is that accurate? Where were they cast and machined?
You slightly messed up. The bore of the 413 is 4 3/16", not 4 1/8".
In the running for the best video you have ever done.
im honestly suprised you never talk about the LA series and Magnum engines
Shorty girdles are a bitch might make a great UTG shirt!
Great job as always Uncle T 👍👍👍👍👍✅✅✅✅✅
Thank you for the education professor Uncle Tony. Bet a lot of guys woke up when you mentioned bikini girdles! Haha
Modern hemis are fragile flowers made from Old Milwaukee beer cans. Tick tick tick boom.
Nice to know, I have 2x gen1 354ci and a gen 3 5.7(345ci) hemi. Maybe one day i will find a gold nugget gen2 for cheap? Hahaha
Love the hemi in theory but those valve angles are a hot mess. Doesn't the Gen I have like 1.3 rockers?
Great race engine, really wouldn't want one on the street.
You're a regular fountain of information. You fuel my enthusiasm.
I’m surprised on all the Chevy small bock references to me the Buick 350 looks the most like our big wedge
The post Nailhead Buick copied many features from the B engines, but it came along after. The Ford and Chevy engines were first
Got a blown methanol 354 Hemi at .090” over (370 inches) and filled to the top with RocBlock. 4 bolt splayed caps. Nothing outrageous. 11.5 compression. Ported stock iron heads with big valves. 7 inch rods with a Pontiac big end (makes bearing much easier to find). Looking at 20-25 pounds of boost. Still rebuilding it. Long block is done. Getting fuel system sorted out and have to fabricate the blower starter stuff and I have to get the starter. Then I can fire it up.
UT you're a bit eccentric but at least you don't put 353 Detroit diesels in Road Runners.
