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.

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.

[QUOTE=wrd1972;14969855]I bet its a L98 TPI.QUOTE]
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![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
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.

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.
