My car is a 91 z28 with a 350 has 50,000 original miles and is my daily driver, so far i have slp headers, flowmaster catback, and a airfoil, next i wanna port my plenum, get intake runners and intake base. After that i plan on getting heads and a cam, what runners, intake base, heads,and cam should i get. also what kind of horse power am i looking at after this is all done.

 

You're running TPI, be more concerned with torque than hp or you'll ge discouraged reallllllllllly quick.

As far as intake setup

Mike davis has a 12 second 350, not to mention in a heavy car using a ported edelbrock base and i believe TPiS runners.

I think TPiS is a huge ripoff, but he's going for a stock apperance

without those limitations i'd say Edelbrock base, SLP runners, and port your intake

Heads all depend on what power you want and where you want it

You could even get vortecs and a scoogin base, i think thoes are in 12's and the heads are cheap as heck.

anyways, good luck

 

What is the concensus on siamesing the stock base? Thoughts?

It will provide the higher RPM flow if thats whta you're after

 

I am playing around with the idea. For now i'll retain the factory cam, and clean up the heads. With 3.73's and a factory stall, I guess it should help if I tune the fuel pressure, right? I run 50 psi at 4500 ft above sea level. That nets me alt. corr. 13.90's on my current set-up. Any ideas?

 

I was thinking of getting trick flow 23 Degree Heads, 64cc CNC-Profiled Chamber which one out of theses 2 and which trickflow cam ??
