That is why I wanted to know what would be better. I was planning on buying a IROC with a blown engine/tranny, and either an LT1 or LS1 that was in a wreck just to use the engine/tranny etc, just like you are doing. How much hp you trying to get out of yours? I will be looking to get about 500 or so rwhp when I am done. The Best V8 Stories One Small Block at Time
I did go pretty crazy on engine appearance and you'll be seeing a lot more stuff in the thread now that I have the @#$%&* floor pans done. Never again!!! Next time somebody gets paid to do it , not me!
Both are fine engines with a lot of potential, however the LS1 will cost you more to buy and much more to install; after all the LT1 basicly a refined small block chevy that can be packaged fairly easily into a third gen chasis. The LS1 will require custom motor mounts, exhaust, PCM, wiring harness, also you will have to sort out the instrument panel interface (most of th LS1 guage information is digital), you may have to modify the accessory brackets, the front cossmember or perhaps both. And then there is the returnless fuel system, you get the point.
