Okay I have a 305 TPI right now out of my 87 IROC-Z28 Camaro and it has 160 something thousand miles on it well I know I could run that forever but I want something new. I want to buy a crate engine but I want to keep the TPI. What crate engine can I buy and do this with? Ive seen people do it with a 383 and stuff but the TPI never really worked right so what engine can I get keep the TPI and just *** bigger throttle bodies etc.? BTW I want some big ***** under the hood

 

ZZ4

 

ZZ4 with stock TPI didnt think it would work from what i heard

 

What did you hear wouldn't work about it?

 

Umn I heard like the TPI was not giving it enough air or gas or air/gas mixture or someting like that

 

TPI never gives enough air


a crate engine is a 350 the same as an L98 is a 350, why would a ZZ4 crate be incompatible (its not)


Choose your displacement, then pick your crate accordingly.

If you EVER want to see power you're going to have to do alot more than stock tpi ontop of the crate engine, the power isn't in the rotating assembly.

 

I did plan on putting in bigger ijectors and 58mm throttle bodies. Whatelse could I do?

 

the power isn't in the rotating assembly

i wouldnt put it like that
