Hi all! Loving my car a ton!! 89 iroc z with the 5.7 litre. Needs a little more power though. What im wondering is this. What is the best cam, intake, and header combination for this engine/car?

 

What kind of power do you want and how will you use the car? Do you have to pass SMOG?

 

no smog test. Its a daily driver. Im just looking to not spend a ton, ya know? I know what a reqest this guy wants to have power and sound but doesnt want to spend anything. Hahaha.

 

On budget this would work well

Ported plenum
Edelbrock lower ported
Stock ported runners portmatch
Headman long tubes with y pipe
ZZ4 cam with 1.5 rockers
Custom prom with timing advanced two degress

 

Or a cam that really complements the low and mid range punch of the TPI system. Like this one:
08-412-8 - Xtreme Energy?
The ZZ4 is decent. Likes to rev a bit more to make its power. Good choice though if you can find the $75 take-out deals.

 

The TPI is really going to lose its ability to move air above 4500rpm on a 350 CID engine. If you are planning on going to a short runner intake setup eventually, the ZZ4 would be a good choice. But if you are planning on keeping your long runner induction setup, there are better options out there such as what was stated above.

Good luck and enjoy!
