I have a 91 z28 with a 305 tpi,will I beable to keep the computer and everything else on the motor if I change the cam set up to a flat tappet cam istead of the roller cam and will the push rods from the roller fit the tappet?

 

why would you want to go from roller to flat tappett? if you stay roller all you have to buy is a cam, you can get a used lt4 hot cam for about $100 plus there is not as much of a headache with roller, no lobes rolling off. if you go with a big cam you will have to change valve springs, mabey work the heads, and yes to computer tuning will need to be done.

 

okay,,whats a good roller cam to get for a 305 with good pulling power from idle to redline and somewhat of a rough idle(I like the sound)?and the specs on the cam and where to buy?

 

"Rough idle" and "TPI" shouldn't be used in the same sentence.
