- THE OTHER GUYS CAD 500-BOOSTED BEHEMOUTH! TURBO TORQUE MONSTER. HAVING RUN THE 500-INCH CADILLAC NA, WITH NITROUS AND WITH A PROCHARGER (THE CAD CO MOTOR), THE LAST THING ON THE TO-DO LIST WAS RUN THE BIG CADDY WITH A TURBO. FOR THIS VID-I WHIPPED UP A DIY TURBO KIT WITH A 62-MM PRECISION TURBO. THE QUICK-SPOOL TURBO WAS COMBINED WITHA CSU BLOW-THROUGH CARB. CHECK OUT THE RESULTS AT DIFFERENT BOOST LEVELS. TALK ABOUT TORQUE.
Best GM truck engine that never saw a truck.
That engine in a old truck would be a pulling beast. Axle creaking torque.
An old truck with a 14 bolt or a Dana 70!
I bought a 500 from a dude that had it in his 76 c3500 and now he's putting a 12v in it😂😂
I have a 472 in a 86 c10 and lone it
annonymous ? You lone it? Cool, I'll be by later to borrow it! Thanks!
@@donellmuniz590 dana 60 on the front. i want that combo on my square body subourban
You're a fabrication whiz, could you whip up a manifold and drive setup to put an 8-71 on that bad boy? Some 425s had an aluminum single plane low rise intake, that's a start.
Hopefully its just head gaskets and nothing cracked.
The Caddy motor with a turbo on it is what is going into the Go-va ... isn’t it? That will be awesome.
Port inject that baby and tune for the turbo!!!
Little turbo and too much timing. For the love of God.... at least an S480!!
I'm building a turbo caddy motor for my '72 hearse right now and I'm pretty sure you could put that child sized 'my first turbo' that he used here in the inlet of my Work S475.
@@TheRockabillyArts some dude around here has a hearse , but i think it's an 80s model but looks pretty badass.
Has a butterfly hat poking out of the hood ,and when I saw it recently out and about he did a straight axle up front.
Has a neat gasser look.
@@MrTheHillfolk what area is it in? I might know them :)
@Dave Stephens That's why it blew up! ioi!
@boost creep I'm new to turbos. My msd ignition has a time retarding function built in for boost or nitrous. Do you think 28degrees of timing is to low for boost? Or do you think it's the back pressure?
Richard Holdener: he blows engines so you don't have to.
Nice work. That thing produces absolutely brutish torque. Tear her down. The 500 caddy will rise again!
You just proven my long-standing argument that low boost is a very usable power option. The numbers at 5psi are still some seriously serious power and torque..!! On a daily driver, that is still one VERY serious amount of torque and HP....., while relatively harmless to the engine.
I'd love to see a 425/500 inch Caddy or 455 Buick with just 2-3 lbs of boost, just for giggles...
or, why not... How about 5.3 lS with only 2-3 lbs of boost?
I read a 1996 HONDA GOLDWING had a small turbo, boosted to 4psi. Ran between 2.5- 5.5 boost. Got 68mpg on cruise, 2.5 boost. From 35mph to 120, in under 5seconds. It was a rocket!! So, maybe it would do the same with any motor. It seems it would keep the motor from working harder to draw in the air fuel. Idk. Just my 2c
I have parts to fix it. New forged pistons and H beam rods.. lets trade some junk? I need gen 2 LT1 stuff. 😁 Oh, and id live to see this with a centrifugal supercharger!
we ran the procharger on the cad co motor-that video is up
I have LT1 stuff to trade for Caddi parts!
@@richardholdener1727 LOL! thats right... I cant keep track of all the builds and testing you do. Now I have to go back and watch it again.
@@caseyhill5261 lets talk!
Richard, I hate to say that I told you so, but big Cads need a good headgaskets, See Flatout gaskets for one with stainless fire ring. They also need heads surfaced along with the block and head studs for boost. I really appreciate your work on the Cadillac. Got one going in a '66 c10.
Boosted caddy motor in my k20? Richard, you are giving giving us naughty ideas! Please fix this motor and give us 1000ft lbs of torque!!
I know it has the potential
When I was a kid my grandfather had a 500 caddy motor on his sawmill...he had headers sticking straight out the roof...everyone new when he was at work...😁
I'm sad that it's injured, but hopefully it's not serious! Cheers Richard.
Don't be sad that it's gone.
Be happy it was here
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,Time to check the bottom end for stretched rods and bad bearings........Guess they won't put any more time and money into it......
Even if it's NA, I'd like to see a 500 Caddy in a Nova.
seen 1 years ago in a chevette and a camaro
Me and my dad both have Cadillacs in our trucks and my dad is about to buy a nova for a Cadillac engine he is building
If it was in the Nova with 4 webers on it....
I have a 1970 nova with a built up 500 I built it in 93 it’s awesome and hauls. I built and beefed up THM350 with racing sprag and tough frictions. I have taken to the strip many times with 3:08 posi my best time is 11s no slicks and street gears I have a Dana 60 locker with 4:11 for it I’m thinking it would turn in the 10s love this pig very reliable and gets about 17mpg and torquey as heck does not use oil at all
Come on Richard, you put larger turbos or even twins on a 4.8!! That little turbo was blowing fire!!! Stud the heads with an S480...Please use at least a t-6 flange turbo. lol.
what was the timing at 10psi? I have a 500 with twins and have no idea where I should be, im used to the LS stuff really.
Oh well , a caddy autopsy video will be good also 😎 built it back up and send her
Caddy's are indeed stump pullers . Very cool engines
"Stump pulling engines" - aka, engines that don't flow worth a damn, but have a bunch of displacement to at least be interesting below 4500RPM, lol
I don't think people realize that engines with a LOT of head flow are torque monsters too; you just don't notice because you're too distracted by the right side of the graph
@@RyTrapp0 to my knowledge these engines dont flow horrible
Klassen Kustoms they're basically a big block with small block heads
Stud it and mls and give it all the boost
Don't forget Richard's fav mod... RING GAAAAAAAAP
@@rhubarbpie2027 and no rod bolts🤣
it did have extra ring gap when assembled at Cad Co
@@richardholdener1727 this is the way🖖
@@richardholdener1727 don't worry it's just a blown head gasket
My Dad's 1970 El Dorado had a really long front end, so, yeah, your turbo set-up might actually fit!
That would be sick
😂😂😂😂😂😂😂
Perfect size turbo for low rpm response. So have built the 5.9 magnum yet? I want to build a torque monster 5.9 magnum. Would love to see that video!!!
Not yet
Better to have this happen on the dyno than in the car 200 miles from home.
I want to buy a Caddy convertible just to do THIS!!
Why did you use a small turbo ?
I guess the 78/75 could make much more power
to have immediate response at 2500 rpm
R.H. ...............WELDING IN SHORTS YOU WILL DO ANYTHING YOUR PEOPLE ???????? THUMBS UP BADMAN !!!!!!!!!!!!!!!
#welder'stan
Do you know how much back pressure it was making?
All of it
The fame that this former Hooptie motor has developed.
Torque freak. Great "RV motor." And apparently they got better MPG than you'd expect; better than a BBC.
If all you can get for this motor is composite gaskets, I have an idea. I'm trying this on my Subaru EA82 which is a similar beast with only composite gaskets available. Nelson Racing Engines posted on a facebook that they coat their copper gaskets with a aviation sealant to prevent leakage. Now granted, that's a very different gasket, but I picked up some aviation form-a-gasket and I'm giving it a go. My thought is that if I can sort of glue the head down to the gasket, and increase the friction between the gasket and sealing surfaces, the gasket will be less likely to push the fire rings out under high cylinder pressures. Just a random idea! Worst case I wasted 15 bucks and my heads are hard to remove. But on my old Subaru, if it blows, it's probably going to really blow.
I just subbed to your channel so try and upload a vid for us please
@@snoopy5736 I'm working on it. I've got a backlog of footage to edit, it's just such a drag haha.
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,some guy had mentioned earlier,,,,,Retorqueing the heads after a few heat cycles ; was surely the real shit.......
My guess would be too much timing I've had a lot of turbo v8s and I usually try to run 15° or less on pump gas I realize the Cadillac probably has lazy combustion Chambers though

Bloodviking master engine builder
Rich said what i did back in 1986. All cadillac 472,425,500s need boost. Bloodviking
Richard, find one of those 1970s FWD GMC motorhomes, the shorter version, swap out the Olds 455, for a twin turbo, and nitrous 500 Cadillac, take it on a race week. Biggest tire burner around! And a place to sleep.
I have two of those things in the back yard, those 455’s have headers, and aluminum intakes too.
Nah, Nova first
Even in a heavy A body or 70s Impy, Monte with a 2.xx series gear that could kill tires and ujoints.
Nice to see something different. 500 lbs around 2k..yikes.
I had dropped one these bad boys into my 79 caddy coupe Deville 2 door and caused problems for allot of mustangs and Camaros...
Ooof. This thing needs an EBC to limit low end boost/TQ. I'm guessing that crank is cast and won't last long at 800ftlbs. BTW, pick up a security camera, stick a 500GB MicroSD card in it. It will record whenever something is happening and just loop over the old video. Never miss a thing. Check out Nelly's Security.
I loved this video so much that I had to watch it again! That engine looked like it was going to jump off the stand when you let off and I could just imagine what fun this would be in a suburban or an ElDorado. We need a 455 Oldsmobile in the other guys engine series!!! I’m thinking the caddy is one of those temperamental engines that needs the heads retorqued after a few heat cycles.
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,so true......................................
Hey bro, I love it!!!! I have a 76 500 out of a sedan, so i dont have the restrictive manifold and i think this gas crisis cam will work well with my giant turbo I got from a CATERPILLAR DIESEL RIG! It has 2 huge rectangle exhaust side by side inlets and the snail shell has to be 12 inches. That remote mounted is my idea, but if you find one, try it! I figure low rpm and similar size profile is perfect to slap on your interchangeable set-up and give it a whirl! Good luck, I hope nothing is broken beyond repair!!!!!
When you get 1000 hp out of a sbc with aftermarket block it's hard to justify an engine with big money parts and a heavy crankshaft. Hence the cad 472,500.
Bloodviking
I did this back in 1987. With twin diesel blowers. T46 I believe. Made 1200 or so hp.
Bloodviking
So wanted to see her crap herself. Excellent water pump! Would have been an excellent advert for the head gaskets if she didn't blow. Mind you at 800ft-lb torque something had to give pressure wise I guess. And in this instance it was the head gasket. Excellent experiment vid. 11/10 Richard Holdener!
ARP head studs and better head gaskets
Good studs and fire rings, put it back up there and lets rock! I won't be happy till the Caddy does 1000ft-lbs. :-)
It went from 350hp and 496ft lbs to 542hp and 788ft lbs with 9.5 lbs of boost :)
Why not a turbo from a diesel? You're giving me ideas about my '73 500 in my '86 Regal. Next time get a 3800 L67 from a gtp or a L32 if you can
Cadillac 472,500 all suffer from slow throttle response due to a very heavy crankshaft.
Very nice, gm should have built this.
Right, they made the 4cyl instead 😪
I didn't think you would get much out of that little turbo, but it looks like you got too much! Lol
Without raising the boost above 10 lbs, what do ya think water/meth injection would add to her? You could run more advance, if nothing else.
Crutched my little vw turbodiesel for years with no intercooler by using water injection and blowing it right into the turbo.
Heh, I used the original rabbit window washer bottle 🤣
Worked awesome
A bbc with a truck block tall deck can handle 2000 hp.
A sbc is maxed at about 600 hp before breakage.
A std bbc can handle 1000 hp.
They say a cad block can take 3000.
I'd love to see that thing with some better head studs and head gaskets.
Dammmmm, 😍 I'm in love with that setup
5252 magic rpm sweet spot.
These were a sh iiii ttt motor back in the late 80s and still sick.
Big bucks to build compared to bbc 454 or sbc
Bv
I really hope you do a big bang 500 that would just make my month probably even year😂😂
You just saw it.
When you can coax 850 hp out of a street motor then you have something
Bloodviking
It would be great if you were to let us know of the turbine housing A/R's on these tests..
Let's see some cad company or bulldog aluminum heads, offset ground crank, higher compression and a cam with 300 or so degrees of duration and 5-600 lift.
please take a look at the cadillac playlist-that video is there
I am awaiting the L67 supercharged big bang.
I've seen 1000 hp at 34 psi on stock bbc. But not loaded in a real world app.
Love it I like those I have them in my 67 C20 and 69!Riviera
I had my first cad 500 in 1986. It was a dog. So I boosted it.
See Nitrous IS cheaper and safer for engines than Turbos.
Do you know if that motor can be mounted to a manual gm truck trans nv4500 ?
I don't know anyone else who'd be so happy about blowing up a motor.
Just a head gasket. He did a good move in pulling the plugs and turning it over. As long as it doesn't sit with water in it, it will be an easy fix
,,,,,,,,,,,,,,,,,,,,,,,,,richard sure knows the shit.......@@lucysmith4242
I sure hope you are planning on some kind of subframe connectors for that Nova. As shot as the floor pan is if you get that much torque to hook it will twist that Nova like a corkscrew.
Looking at a 62-1 compressor map (I believe Precision doesn't release maps, feel free to correct if that has changed) it seems like this would be a sketchy turbo at 350 NA HP. Assuming 7.5 PSI you'd be at 525hp or ~52lb/min. The edge of the 65% island is at about 42lb/min. The turbine is probably even worse. I'm betting the Precision unit is better than a generic 62-1 but 20%+ better? If they were logged I'd be curious what AITs and backpressure were. I'd be looking for a 76mm turbo even on a T4 frame perhaps even a T6 frame like an S400. I realize you're not looking to make huge power but if you have even moderate air flow the turbo should reflect it.
On another topic how far does HEI on a V8 typically go for boost? Were you running an MSD box or similar? Been curious on that, want to do a budget 350 Pontiac eventually with HEI. I have the timing control already set up for it.
Was about to ask if it was going in the nova and you said it at the end! Awesome! Super cool setup that’s gonna be
I cant wait for my "holdener fab, one size fits all" turbo kit to arrive. Its goin to be the best christmas ever!.
@RichardHoldener Any updates on the caddy problems? Did the water damage your turbo? I watched this again and looks like it could be an amazing engine. It would have been neat to see that last torque curve climb from 2500 rpm up to who knows??? Lol. Btw, my dreams were sweet!!! Lol. "T-N-T" Thursday Night Thinker. After Turbo Tuesday??? Wager Wednesday, With a lot of "I bet ya" phrases,,??? Lol, I will stop now.
keep em comin
I don’t think that bov is working correctly. It didn’t look like it fully opened, especially that second boosted pull. I’ve been wrong before though!
then a big puff of black smoke as the carb over-pressured.
I was looking at that too.
Right, I thought the same thing.
at 45 cubes less the Buick 455 was far more impressive then this boat anchor
What's cool is an old school caddy probably has plenty of room for the tubing
It was hurt before you started.. every time you let off.. it was spitting out of the exhaust
28* maybe too spicy for pump fuel and the 62mm is just a cork in a bottle. Throw on the S480. Fill her up with E85 and go again.
The turbine housing is pretty small for this, the biggest turbo Garrett makes close to this is a gt4288 it has a 63.5mm inducer and a huge turbine housing. They are used on 9.6-12l diesels. With the 62mm precision here I wouldnt be surprised to see boost under 1000rpm.
Peak torque is at 5252. Hp and tork always cross here.
And this, ladies and gents, is what happens when you have a high load/low rpm situation on pump gas in a non intercooled turbo system. Add the high backpressure of the small turbo...and pop she goes.
I dont think you know what's you are talking about.
Nailed it.
At least cam it and run twin turbos.
Bloodviking
The rods are Arma cast iron Pontiac made. They can granade. We used 455 Olds rods modified back in the day. Copper gaskets and a bore ring seal in the top of the black.

They work good in street cars and trucks I have them it two of mine
500 Caddy with a TPI ... 1000 lbs Torque ?
I know this is an old video but it made me laugh at the end, entire video i sat here wondering if those notorious 500 caddy headgaskets were gonna hold up it sucks but did give me a laugh
Just curious how reliable is the engine? I have a 472 the has a 500 crank it’s been bored 30 over. I had it rebuilt for a Cadillac project. But I am thinking about putting it in a z car and making a drag car with it. Nothing crazy just something I can do with my son. Possibly a single turbo or a blower
THIS ONE GOT HURT
You need to invest in a few go pros ... film more more angles etc ...
Is that your response to caley4-knee lockouts... Or YOUR drivers license photo?
Oh, GREAT BUILD, BROTHER. AND NO caddy mills were Harmed during the filmig sessions..
Sounded KILLER.
God vless.
BRIAN.
Please intercool that thing and compare cool and hot intake power
Good show old boy 🧐 (The caddy). Great video sir!! Keep’em comin and I’ll keep 👍🏻
How does the bottom end like turbo on the caddy? Will it last at 800 sir ?
You think it would be possible to do much with a 1976 Cadillac Eldorado convertible custom with the 500 4 barrel Rochester? Let me know man, I'm looking to keep it as factory/original as possible but would like to give her some more juice and a great sound
CAM AND INTAKE
Makes me wonder if the pressure was so high in the lower speeds, does that make the gasket have to “hold on” for such a longer duration or was it a little water that got in and hydraulics did the rest, or did the head bolts stretch and let a little fluid in. Thanks for testing
These engine components are not under a real world load.
Bv
The caddy 500 must be shit if even freiburger and dulcich also grenaded their brand new "built" caddy 500 in roadkill garage. Basically, it doesn't like anything over 4500 rpm. Boat anchor.
WATCH THE 7000 RPM CAD 500 VIDEOS
Hey, huge fan, not tryin to sound like a broken record but if you can find one of them 425 big blocks I'd love to see what you can do to it
425 cad?
I agree. Show us what you do to make one of these lightweight engines survive at double its original output.
@@richardholdener1727 yessir, i got a 1978 sedan deville with the 425
@@richardholdener1727 easy to find in the bone yard. Usually pick up cheap, like 150 bucks. '77-79 Sevilles.

Only able to one like because UA-cam is lame.
Ever Dyno or work with the 3.6l HF or HV V6 Engine? They are everywhere and usually are good for most of 300hp. Nobody plays with them though.
have not
that engine on boost is pretending to be a turbo diesel, bucket list engine
Oh please put the turbo back on or a blower with low boost in the nova.
So, let’s say that was a twin turbo set up, wouldn’t the numbers improve due to lower back pressure, thus allowing slightly cooler engine temps that would save the heads/gaskets for a higher level of boost?
when sized to make the same power, twins do the same thing as a single
gawd dog even N/A thats one honkin truck engine. OR in a camaro with 2.73 gears for pure highway hell.
