Why go carb'd? EFI is a wonderful thing, I hate seeing people give up with electrical things and slap a carb on there.
I went with improved stock parts, ported heads, polished lower intake and abunch of other bolt ons. Looking back I wish I would have bought the Trick Flow kit, Holley kit or the Ford Racing kit. All of these are pretty stout packages that can make these little 302's sing! To make a big number he is going to need the add ons- Bigger injectors, throttle body, MAF, full exhaust. You have to pay to play!
