Best TPI replacement

Hey guys I am looking at building a 383 stroker pushing around 400HP for my 86 iroc and wondering what is the best replacemt for the TPI. Are the FIRST intakes any good? What are your recomendations? Thanks!

It all depends on what you're looking for out of the engine, what stall speed and gearing you have, and budget.

If you have around 400HP, I'd only be looking at the FIRST or the StealthRam.

Re: Best TPI replacement

Once you add throttle body and fuel rails to the stealth ram they are about the same price.
