Hi, i was wondering if yall could help me out, effectivly this winter i want to do one of the following, but what sounds best for max hp. Should i rebuild the tpi with high performance parts, get a crate motor instead, or maybe shop around for a lt1?

(question 1) Suppose i went with the crate option, Could i get the zz4, and put the superram, runners, and just port my base to fit the runners, use all the stock computer harnesses, and add a supercharger ? Will that work with all stock emmisions, AC, other that the fact ill need a new ECU ?

What is the best option ?

 

Hey,

To answer the crate engine question. If you intend to supercharge you might as well build an engine for it (cam, forged pistons, lower compression). Although not necessary it would be a pretty good idea.
