I have a 91' Z28 305 TPI now, I want to put in a stock L98 (350), with a cam that would increase my redline to 5500-6000. Now I know that stock parts are barely good enough for my current redline. What parts will be needed to make this cam do more good than evil for the car? Do the heads flow well enough, would a port and polish get the job done if not? Also how about the ignition system, is it able to fire effectivly in that range? I want to make a cost effective 350 TPI that'll take me into the 13's for now. Is there a beter way for this than what I'm doing?

 

You're beating a dead horse. No matter what parts you change the one thing that's holding it back is the intake. A factory TPI is useless above 5000 rpm.

Swap to TBI , j/k
It is an option though, the short runners help with the high rpm. It's either that or spend $$$$ for an aftermarket TPI system. Then there is always the carb if you don't mind the 8mpg.

Errr....damn...then what should I do. Want to get into the 13's by this summer and without a bottle to help. What should I do? Now i can't build the 350 because I have no place to do it, so any swap would have to be done by a shop. Would it be better to just stay 305 and build it up?
