How much HP from C/I/E LT4
How much HP from C/I/E LT4 I'm curious about how much power a LT5 (my bad I meant LT5) with a mild cam, new intake, and headers would make cause today I was at a friend's shop getting the crank pulley off a 6.0 I'm rebuilding and he showed me an LT4 Corvette that they had in the back. It looked like the car spun out and the tail hit a pole or a something but the engine was good. He told me how if he had know I was looking for an engine he might have given it to me knowing how I'm a heavy Hiperformance type of guy so I told him maybe for my next project.

You would be better off selling that engine to a collector who is / may be restoring an LT5 corvette. It is a very expensive engine, less than 7,000 were ever produced.
Finding aftermarket parts for it is going to be expensive and arduous as well.
Do yourself and the engine a favor, dont cobble it into a pick up truck. Sell it and use the profits to build a badass conventional SBC, Gen II LT, or Gen 3/4 LS series engine.

Yes it does I thought it was an LT4 at first, hence the thread title, but when I saw that the manifold didn't match I tried LT5 and lord and behold it was exactly the same. I also just saw in a website how expensive these are so I had the same idea. I might get it from him and sell it.
They can make really great power and go up to over 400 cubes, 415 strokers and so on, LPE and DRM have both been building them since they were new, not cheap though. Your dealing with a cult following with VERY deep pockets.

If it is a LT5 engine, take it and sell it and it could fund the rest of your build easily and destroy a LT5's best effort for a fraction of the cost it would take to build that LT5. They are junk. Keep tools as far away from it as possible. There is a reason the engine had a short life span at GM. As far as upkeep you'd most likely be better of with a late 1970's Jaguar. I was always told the engine cost more than the brand new complete/rolling chassis it went into. If it is indeed a TPI motor, run like you are on Martin Luther King Blvd.

that would be a bummer. I didn't pay much attention to it cause he said LT4, but tomorrow I'm dropping by and I'm gonna take some pics. Hopefully it isn't a L98.

if its an LT5 they dont fit in F bodies very well, when I blew my original motor I actually experimented with this very idea, sadly i didnt have a garage to do the work in but was lucky enough to have a local racer as my mechanic, and he was all for it until we started doing research, its a little too wide for the fenders if I remember, youd have to try to snake custom manifolds or headers in there, and youll be paying a lot to get those made, then youll have to get the cams from DRM (theyre kinda the only guys I know that are still big into it.) but the cams are gonna cast you about 3-400 a stick. Heads....they dont really make heads for these youd have to send em to DRM again and thats like another 2-3k. And after all of that you'll make 5-600hp at the flywheel, this is all doable for cheaper with a standard LT1/4

You have no idea how hard it was not to scream from joy
It's already up on the texas classifieds if anyone is interested.
It will include the transmission and I'll do everything I can to remove the whole engine harness without having to cut a single wire.

Holy ****, you sir have found the grail of LTs. Enjoy your new found youth...err wealth!
But
I would sleep better knowing that this piece of GM History is making it's home in a C4 Corvette and being put to use as it was meant to be. Roaring down the track at full speed.
