I have a 91 Z28. I have flowmaster exhaust, slp headers, wires, plugs, TPI, and a chip. I want a pretty aggressive cam. The ones with that more rough idle. How big can i go?

 

Is it a 305 or a 350? We all really need to know before we can help in selecting a cam for it.

If its a 350 as my car is, I have to champion the LT4 Hot Cam from GMPP. Although I am currently in the process of installing it, I know its a cam that will work well for my engine as well as yours.

If your car has the 305 motor, the only semi-first hand knowledge I have is with the smaller of the 2 SLP cams. Although pricey it worked wonders on my friends 89 IROC 305.
