- This time they find a junkyard Cadillac 500 big block and use some modern-day performance parts to make a monster out of GM's biggest luxury car engine. As expected, the final truth is in the dyno numbers.

My grandfather was a hoarder of old cars, he had 12 caddies. All 472 and 500 engine's
Yo hit me up if he might sell the engines
Got any eldorado parts laying around preferably 76
I spent over 40k on several 425s and I finally got a 500 caddy that was super built up. 500 hp 600 torque built by cad. Co. In Albuquerque. Yes they dynoed it.
The problem is very few people can build them properly. Yes they make tons of torque but you can get a crate motor with warranty to do the same that is lighter. Once you started getting more power out of these engines with bolt ons and cams look out your wallet will look like a Ethiopian. I had 3 caddys I drove over 24 years. I worked on them nonstop. I also rebuild the transmission, differential which was a posi diff out on a caprice, brakes, suspension you name it I did it all. That Ole 1979 caddy with that 500 could outrun just about anything. It was a 500 swap. The engine I had out probably 8 times and the th400 took 2 hours to get out and I'd have it completely disabled flat. I know every bolt in that car top to bottom including torque spec.
The 500 is so slept on it’s a beast!!🔥
I never understood why people would choose the 472 when for a few $$$ more you could have the 500... :) My dad had a 1960s caddy in the 1980's I always loved that car!
@@barking.dog.productions1777 lol I know that’s right! Man I bet that thing was real nice!!
@@darealyunga.v.3392 It had real style, all them fins and chrome, and a low rider too, and it was shorter than the seventies caddy that came after... Those 70's cars had trunk and hoods about 6 foot long each... lol
A blessed and prosperous new year to you, brother...
@@barking.dog.productions1777 that’s a true caddy for sure! I love them lowriders tho lol those trunks could fit a family in them😂 same to you brother stay blessed and have a great 2022!
Answered in the video at 1:45. Max HP from the factory was a mere 190 and there was no aftermarket support for a long time. That changed when performance parts became available.
My Dad use to service trucks for a local tire shop that used Ford F-250 trucks. When the engine would south which they did as he bought these trucks used and then painted them in his company colors my dad wouldn’t bother with a ford engine. Those old Cadillac motors and transmissions were a dime a dozen so out came the ford power plant and in went a Caddy set up. The guy like them so much he had my dad rebuild a 500 and put it in his ford crew cab.
This is the motor that the hearse on Power Nation SHOULD have gotten! Revisit this project!
This is an old show I seen this many years ago, look how young Mike is.
Used to have one of these motors in my 76 Sedan DeVille. So much torque. Thanks for the great, thorough video. Reminds me of the detailed videos from the glory days of car shows on TNN when I was young.
Yep...had one in my triple white 75 Sedan De Ville 4 door hardtop. Even in 70s emissions form it had gobs of torque. I was 19 and had some good times in that car 😂
@@scottclark7559hire much mpg do you think that build would get? I have a 500 and it seems like I get 10mpg. Wouldn’t this make mpg worst? (I’m not a gear head)
My Grandfather always had a Cadillac when I was a Kid in 60s/70s he always told me if they were to make a Cadillac race motor it would be a monster well you guys have done that this is way cool and nice job
Loved my 1973 472 Cadillac ,I'm happy to see others that appreciate these torque monster's!!!2021
As a fellow southerner I can tell you with confidence that when you hear a southern gentleman say "shoooooot", some good things are about to happen lol
Love it! Use to own a 73 Sedan DeVille with a 472!!
Very enjoyable engine build.
A 106-108 lobe separation angle and another 4-6 degrees at .050” on the exhaust side would have made that 598 hp into over 610-620.
They didn’t give cam specs🤦🏻♂️.
Watch Richard Holdener. He did a couple of videos on the 500Ci; that caddy with its good compression and head flow can make well over 700hp N/a. It was also making more torque than horsepower which shows it had a very mild cam in it
Just a velocity stack would've probably got it there. 👍😎
@@doomtrooper2909. Lol, no, but it would save a lot of money🤣
@@bri-manhunter2654 basic stock 500 with a decent cam will make around 300 hp and 400 ft lb of torque add headers and a decent intake and 450 hp 500 ftlb of torque...
I need one of these in my hi-top ex uhaul 30 ft bob truck the big question is what about the tranny to fit this in???? It is originally a 454
@@barking.dog.productions1777. Would be fun sir!
I'd replace the intake with a dual plane for the longer runners, to bump up the mid range TQ. I went from a Max Wedge Indy heads and single plane EFI intake on my 500 Mopar, to a longer runner ported Edelbrock Pro Flo XT intake with standard port TFS240 heads, and gained approx 40 ftlbs at 4400 rpm. With nearly the same cam specs at the Caddy, the Mopar (installed in a jetboat) turns the same spec'd Scott Jet 912 drive at more RPM than the KEM LT4-650tq/650hp marine engine.
One day a thousand years from now researchers will read this comment and assume it was in a foreign language by visiting aliens.
Weber power plates

Gracias por el vídeo y gracias por mostrar tan excelente trabajo del mejor V8
great segment on arp!
Dunno so much about 'pulling up stumps', that thing's more likely to just suck the entire tree clean out the ground and into the intake.
Great vid!!!! 👍👍👍
Technically speaking GMC offered a 638 c.i v8, albeit a truck motor.
Heh, yeah and it made all of about 250HP :-D They even offered the Twin Six, a V12 version of the same 60 degree V6 that they made into that big V8. There were some cool things about the design, but the low compression ratio (7.5:1) tiny valves and poor breathing let it down. I have the 351cid version of this V6 in an old school bus.
Went 10.09 in the 1/8 in a completely stock 1970 4 door hardtop 472 with single exhaust. All you could really hear when it was coming down the track was wind and the ol quadrajet moaning. Everybody had fun hot lapping it never even offered to overheat drove it home.
Back in the late 80s early 90s I put a 76 500 caddy in a 77 GMC half ton pickup it was a real fun tire shredder got about 8 mpg with 3.40 or 2.56 rear gear didn't change anything but the smoke off the rear rubber. Lol @memories
I put a 500 in a 75 Chevy Blazer and used a 2.56 rear just to help from spinning 😵💫 the tires 😳
Engines are so interesting and sexy best part is that you can almost always rebuild them way cooler than electric motors.
There was a guy that ran an s10 pickup with an Alston front end in N.E. ohio with a 500 caddy in it . Ran in the 10s all day long . Never broke .
. 090 over and look at how much beef there still is between the cylinders!
It would be great to see a weight-saving, yet stout, crankshaft and see that monster rev!
Always loved ARP and now seeing what they do these will be the only fasteners I use just love the quality and QC checks.
Unfortunately they're products are hard to acquire currently.
@@maynardreed8374 not in Australia there is plenty of stock for most builds
I won't support a company that discriminates against white men for the purpose of employment. I'm so sick of this antiwhitism, and I won't tolerate it anymore.
They've been real good for me too. I have them in repeated use for the last 13 years. Haven't had any break yet.
Can’t hardly find anything ARP in the states nowadays. I bought the last ARP SBC crank bolt I could find, and I searched for days.
They left so much power on the table by going with that cam.
Could you explain I got a 500 I'm gonna try to rebuild after I get a few hundred thousand miles out of it and try to get the most basass motor I can what is important when it comes to rebuilding and getting cams and all that
@@shakinbottles
Explain what? More cam = more power?
248 duration on a small block is a radical cam, choppy idle, good power up top. On a 500, a 248 cam has smooth idle, good power though out the RPM range.
My favorite motor also. I love the enthusiasm
What they didn't show here was that the TMP Stage 2 carb got power to 640hp. That 950 Holley got smashed.
RIP Marty Lane.
MTS helped me with my 1973, 472. Basically, a stock rebuild with an Edelbrock manifold and mild cam. It was .030 over with 8.5 to 1 CR, and made 365 HP, on 87 octane, at 4800 RPM.
It doesn't take much to breath life into these monsters - they were so neutered in the 1970's and 1980's that if you just put a decent cam into them and let them breath they will easily pull all kinds of HP but especially torque
You got a raise the compression
@@danasmith1899 Don't need it. it was in a 2000 LB Rat Rod. LOL!
Yes I want to save and put one of these in a Chevy flatbed
Just grab a 454 or 496.
Agreed, im all for unusual powerplants but the BB chev is a drop in ,readily junkyard available, and will supply the same power numbers, or more, for much less money.
You can get a 454 for dirt cheap. That caddy will set you back a lot more, and the aftermarket just isn't there unless you want to spend thousands to do what you can with a budget big block Chevy.
@@TheSleepyMechanic0524 won’t make the same type of torque at such low RPM
@@aboriginalmuur1661 bs. All about your cam specs, heads, intake type, timing, exhaust size and many more things.
Between the guy in I do Cars tearing them down and you guys building them up, I finally sort of begin to fathom how my truck engine works and why oil is so key.
Got a 75 sedan deville with a 500 sitting in storage. I had no idea it had this much potential. I'm gonna have to make a spot in the garage.
Nearly 600hp na on pump gas is freaking golden
500 caddy mtr w/472 heads all you really need low buck HP no trick stuff...
12.5:1 compression.
The low compression blocks are different to the early ones. You usually do the 472 heads to boost the compression of a low block.
These things are torque monsters. Cam it up and lose some hp on top. Lose the headers and put it back in the Caddy with a quiet exhaust.
Nice
The Cad Co. has gotten over 1000 HP. Stock crank.
as a little kid growing up in the 80s my folks bought a used 1977 caddilac sedan deville 4 door with a 472 big block . when we moved to the branson area in 89 and the car got parked because the suspension and wiring started to take a crap . my dad had a plan to yank out the working motor and tranny to drop in a project 72 Chevy Nova . well that goal got shit canned and the car got hauled off for a couple hundred bucks 🙄
There was a guy on the east l think his name is Kevin brochard that made a kit to drop 472 500 ci caddy engines into gm G bodies. Supposed to do 12s with stock 500
425 My Boy
@@terrellstevenson3356 425s ok just couldn't lean on them too long. Or maybe we just were not building them right.
1974 was the last year of the 472. 1976 for the 500. I think 1977 would of been a 425 that later got replaced by a 368.
@@gmac8852 They make a kit for G bodys and they fit well. A stock high compression one will run 13s in a G body while shifting at 4500rpm with 2.73 gears. They must get valve springs and rocker arms to rev past that or if you put more cam in them.
Weatherstrip adhesive for the oil pan? Was this recorded before they had High Tack or black RTV?
that big block deserves a set of a huge twin turbo set-up now...and double that torque & power...
the manifold looks like a airgap style !!
The caddy company Albuquerque New Mexico sales all you need 472 Chevy Silverado pickup 1987 puts the third chunk out of the 70s rear wheel drive Cadillac car transmission and motor they sell a kit look up the caddy torque monster build out of hot rod by Dick Miller
Could you imagine one in a Baja vehicle? Or, a 4×4 rock climber? HP and Torque that close to the same, it would be a beast!
probably break lots of parts but you could sure have fun doing it.
Lots of power
That 59 El Dorado. I would love to get my hands on the 59 Miller-Meteor. As soon as you see it you just know why.
Ecto-1.
I've dreamt of putting one of these into a station wagon, I have the wagon just not the engine
I’m sitting here thinking about swapping out my 500 for a 350sb. After watching this video I would like very much to do this to it but, then I remember that I’m always at the gas station with this 500😊. I get under 10mpg now. If I do these upgrades I’ll probably get 2mpg.
I've always wondered why most of these wind up rotting away in junkyards.
I understand they are in shortage now.
Because bone yards primarily have been taken over by scrappers looking for a quick buck - they no longer care about selling parts - especially for older cars.
I just sold a bone yard my 2000 ford taurus with the HO 3.0 32 valve engine and the just crushed the whole car for 3600 lb at $0.10 a lb - that motor and transmission were worth 3 X that - the factory aluminum rims were worth $100, the never wrecked body parts were worth $1000...
They scrapped it for $400 along with who knows how many classic cars - Caddys were all crushed decades ago by these bastards
@@barking.dog.productions1777 "cash for clunkers"
@@V8_screw_electric_cars Exactly - take our heritage at every chance - stupid people never see that we are in a constant war with big government. They hide it behind platitudes, but the truth is that these older cars are a BIGLY part of our history...
@@barking.dog.productions1777 Also keeping older car on the road assuming it doesn't burn oil is cleaner than producing new one.
I think they misspoke when they set initial timing at 31*.....I think he meant total! Also, them heads flow enough air for 700+ HP and that cam is the bottleneck in this engine and maybe the carb also, try a dominator! That MTS guy didn’t look too happy sitting next to the dyno operator!
Where can I buy parts to do the same build yall did n this video
Largest production block is the 534 cu/in Ford truck block in the late 1950's !!!
I would like to see you guys build a Cadillac V16
Ah. It would be fun to get a 1981 Coupe DeVille and throw out that L62 and replace it with an engine like this.
Monster engine great=3
sure am GLAD i brought ARP Head Studs for my SUBARU EJ207 motor ! = only the best will do !
*"W0W,...'A R P ' IS SIMPLY:

God I hate carburetors nice motor bit would be nice to see some fuel injection ontop of that 500
Try reading the manuals and looking at a flow path diagram for the fuel delivery. Once you understand everything about them, you can truly tune them yourself. With a rebuild kit and minimal tools you can usually fix any carburetor issues on the side of the road.
@@jasonhooey5677 Pretty hard for a carb to match EFI when it comes to fuel distribution, mixture control at part load, etc.
Depends what you want, carbs are simple and cheap and work more or less just as well as EFI if you're only interested in winning drag races. But if you're after accurate mixture control under all conditions, easy cold starts, fuel economy, passing emissions, that last 0.5% of possible power output... then EFI is where it is at.
When I was coming up somebody did back in the day and had one in a nova. Said Caddy 500 on the car.
I miss my '78 Fleetwood Brougham. If I find another one that's in good shape, I'm giving these guys a call and it's going to get some extra power, and lots of it. Don't care about gas mileage, I just want a heavy cruiser that is ridiculously overpowered.
That's what I'm talking about,that's a bolt in for a 472 0r 500 engine with very little mods,and the 77 and up Caddys where much lighter in weight.
Honestly if you drop some modern tech into one of these engines you can probably improve the fuel economy AND the power at the same time. In particular with EFI you could add some compression ratio and timing without having to run special fuel (Without ITBs or very carefully designed manifolds carbed engines usually have some cylinders running lean and some rich, and your compression/timing is limited by the leanest cylinder) while also improving your economy. Also those alloy heads have a modern looking chamber that probably does a lot of good for economy and power compared to what was available in the 70s and 80s.
15:47 got eem
can someone post a link to MTS from this episode? I have a Caddy 500 I want to build, but can't find the correct company.
What we learned about caddy motors in 1985 and up
They suck in stock form, they lack power
Heavy rotating weight
Heads need loads of porting
Won't run on pump gas with early heads on later block
Q jets suck
Force induction will wake these dinosaurs up
Valvetrain blues are present
They coast way more then chevy bbs
The blocks are awsome in strength due to a thick bore and hight nickle content
4 bolts not needed
Cam choices were limited to regrinds back then
A few failed from oiling issues
Don't use the rear sump with long pickup
The p rods bend easy
Don't use the cast rods go with modded olds 455 rods.
The height won't fit under the hood of most cars.
Put the motor in a very lite car.
Don't expect much out of a Na engine on pump gas.
Bloodviking
Left out the installation of the rear main rope seal
why you use a 4 hole spacer under the carb ?
600 horsepower and even more torque, easily.
Lots of money spent.
Those engines run the best With aircraft fuel mixed with 76 fuel
My first car was a souped 75 caddy , nothing could out run it
That engine would be a total riot in a 75-76 coupe de ville! with a turbo or nitrous it could embarrass some muscle cars. 10 or 11 sec 1/4 mile runs in that huge land yacht
So the fins can be traced back to legendary Kelly Johnson when he was only a janitor at Lockheed Martin.
The 69 70 cadillac 472 500 were 375 and 400 hp 525 torque +
How much money is total cost
Bad Seed Chevette anyone? #SteveMagnante
My favorite hotrod article of all time.
The caddy Engine was actually inside of the chevette I still have the Hotrod aricle.They also did caddy hack,cad camaro,cad nova,and cad corvette to name a few.
The one guys reminds me of a rated everyone James tal aka jackstand jimmy .
My dad put a 500 in the rear of a 64 Corvair.
That tiny cam bore is a major weakness when compared to other designs like the ford 460 is it possible to bore it to take a larger core?
If there is material, it can be bored. The question is, what do you want? Reliability or power?
@@sethh8892 You would potentially gain some of both by making the cam bore larger.
You can.
But there’s no point.
@@tclott316 Oh?
@@tclott316 more HP is the point... You have 6 cylinder toyotas, and tiny albeit 3 rotor wankels make more HP than that.
yeah, but what do all those parts cost?
3000 rpm? It made peak power around 4000 rpm or so stock so🤷♂️
It has weak cast rods. I would'nt over rev it. Still the 70 was 400 HP then it dropped every year. When racing my Eldo I have found to let the automatic do the one -two shift then maybe hold it a little longer in second. More gears would help a lot.
I always use ARP not once have they let me down
5:10 if GM didn't design the 1970 engine to spin pass 3,000 rpm. Why did it make peak hp at 4,400 rpm? 6:17 why are you putting gasket sealant on top of a gasket?
the biggest GM motor ever put in a production like a truck was a 637 cubic inch big block it had 5 and 1/8 inch Pistons with a two and three quarter inch stroke
That big block was GMC 637 Big Block Chevy and the GMC 702 Big Block V12.
@@CJColvin It wasn't a BBC like a 454. It was an 8 cyl. version of the 60 degree V6 debuted by GMC in 1959. Sturdy bottom end let down by dinky valves and poor breathing. But it did make a lot of torque and last a long time.
@@Bolton115 Yep thats true
I got a 500 and still haven’t done anything to it yet future project someday
Can i fit this under the hood of a 76 deville ? Without cutting the hood ?
I have a 70 Eldo. Apparently the stock intake is poor because there is no hood clearance. Maybe EFI would give you more. The Eldo has a complex FWD trans.
9:46 ; "initial timing set at 31 degrees"....really? Total timing maybe.
I think that's what they meant.
Most of these dyno builds end around 38 degrees.
Is $200 for a 500 worth it?
Im thinking of putting it on my 73 k20.
A single plane intake on a big block? 0.o
That intake is to much for the street it's nogood untill it gets in to the 5000 rpm area and is nogood for torque or gas milage below 3000 rpm I had one I swapped to to the performer and a Qjet carb I'm almost at 600 HP 644 torque
My forged B18C1 that's in my Civic has every ARP fastener available on it and it makes 709 whp. My turbo J32A2 that's in my 502 whp Accord has custom made ARP head studs. ARP is the best...
This is a very old show but i still love to watch these old power block shows. I want to see the full race 500 on the dyno... what are the limitations to this engine? Love big caddy BOP big engines as well.. they where the easy way to get easy power into anything with a trip to the right junkyard.
Stock conrods are junk. Stock crank is good. Stock heads low performance as well as stock intake. Stock exhaust not too good. See the Cad Co. I thought with all the money spent it would do better.
Anyone else catch how big the valves are at 6:51
The aluminum heads have the valve's too close to each other that makes burned valves in 5 years and aluminum causes whorpage when overheated and carries like tooth decay
What is cost of what they had in parts for that HP
A couple grand less than the ten grand crate LS.
Yeah I will guess $10,000.
Whats the parts cost total on this motor?
Cadillac motors are a boutique motor while mass production has driven the cost of GM big block parts down so Cadillac horsepower is more costly than GM horsepower. FYI All Cadillac 500 motors from the factory are 502 inches. My "57 Coupe DeVille has a 502 inch Caddy motor in it, giving it luxurious grunt.
I went and looked on their website.. holy balls is it expensive. You could build two gnarly big block chevies that would eat this thing alive for the same cost.
@@superkillr Thats why I asked the question, I already knew the answer. Could prolly build a 600hp sbc just for cost of those heads and rockers alone.
@@USARAY1947 Where did you see that? It's apparently 500.02 c.i. not that I want to argue about it 😁
@@USARAY1947 No, they're 500cid. 502 was the EPA engine emissions control designation for this block, that's why the 472 cars also say GM 502 on the emissions label. But yes, they are boutique in that it seems spendy to put one together-but the payoff is you only have to do it once and the reliability in real world usage is stellar.
No the largest engine gm made was a v12 from the 60s
