Iam rebuilding a 350 tpi out of a 1991 firebird. I already have edelbrock tes coated headers and i am going to change the cam
(the jury is still out on that one) one that is not to wild cause i live in cali but somthing that complements the whole package. I wanted to know what single part needs the most attension.
throttle body, runners, base, heads, computer,???? where should my money go first? Iam not rich but if the gain in power is worth the investment i'll do it. Also i was thinking of mild ported heads or vortec/ any suggestions?

 

oh also i bought the motor complete for $900 so i would like to use most of the parts i have if they don't just strait out suck.
my hp goal is 325hp and tq goal of 410tq. thanks

 

If you don't mind grinding you should be able to achieve your goal with even a ZZ4 cam I would think.
