What do you guys suggest on an aftermarket intake. That includes plenum, runners, and most importantly base plate?
I have a 1991 Camaro Z28 1LE 350 auto.

 

where is the rest of the information?

 

Most bases for tpi intakes are pretty similar, I'm running an edelbrock right now. They seem to just have more meat than the stock piece, so you can port them a good deal more. You really don't need to replace the plenum if you get aftermarket runners, unless they are made for a special plenum as in the superrams case. SLP makes some pretty good runners that are somewhat affordable. Is your car a 305 or 350?
