305 heads, need advice
I am looking to "upgrade" my 305 with some heads, cam if needed. My question is though, I have searched and searched on here for some solid heads that would upgrade the motor and it's like everyone has their heads picked out for 350s....
I am not a serious gear head but would like my weekend grocery getter to have a little more pep in her step...I'm not swapping motors either.
I was thinking from what I've read to get:
Heads
Cam
Headers
TBI mods
If I do all this will I have to also buy new tuning for the ECM???
