Best GM truck engine that never saw a truck.

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...😁

That engine in a old truck would be a pulling beast. Axle creaking torque.

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.

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...

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 know it has the potential

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 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.

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

I've been a 500 caddy fan for years. Like over 30. I used to pop headgaskets all the time. If this engine is a .060 over bore you cannot use a felpro head gaskets. The fire ring in the felpro is only at .058" bigger. At a .060 over bore. Probably a couple thousands more you never get a good seal at the cylinders. I switched brands of headgaskets and fixed the problem. My current build is a long rod .075 over bore. 10 to 1 compression. Makes more power and revs better than some of my higher compression combos. If interested I'll bring my engine down. I want to do a twin turbo set up. See what we can get. If it blows up. O well.

I think the rods and piston need swapped to get it up in rpm. The stock caddy rods bolts are the weak link, then the piston won't handle much boost either. Swap those, install a long duration camshaft and he would be good to go.

If I was you I done away with standard head bolts. I put in head studs and put in a thicker head gaskets. Once increase cylinder pressure it cause the factory head bolts to stretch out it will pop head gasket. By replacing with head studs you run more cylinder pressure. ARP head studs won't stretch out like the factory GM head bolts. It's worth it in a long run.

I didn't think you would get much out of that little turbo, but it looks like you got too much! Lol

Because Roadkill, I approve of this message.

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

More Cadillac please

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.

Nailed it.

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.

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!!!

I'm sure it's just the gaskets. I've always heard that turbo Cadillacs have that issue. I'm satisfied that engine would make a lot more power with less restrictive exhaust manifolds. If fact, that mat be part of your gasket problem.
