help w/ fuel injectors im fixing to have to buy new fuel inj since im doing a head/ cam swap
should put me in the 430 - 450 rwhp range, i know i need to upgrade my fuel pump as well, thats easy. i need to know what injectors size i need.
i used the sticky and based lined it at:
bhp= 525
( figured that might be close )
8 injs
47 psi fuel pressure
and came up w/ 39.46
so rd up to the 42 pd injs would be my guess

Go with the Racetronix/Delphi/Lucas 42# injectors and be done with it. The worst thing you can do is to get just enough injector, and then need larger ones when you make other changes. You can tune a larger injector down to work just fine, and the difference in price should not be that important when making the initial purchase. Do it right the first time, and do it once.
