fuel injector size

[lazerred94stang]

A while back some one put a post up of a formula to figure out what size injectors to use with what ever horse power. Does anyone have or rememder it? Or any suggestions. I'm going to be running 6 to 8 psi kenny bell on a 306 thanks..

Those formulas are all BS. I'll assume you have aftermarket heads and cam on that 306 with the blower? You want at least 42's but IMO go 50's since it'll support you down the road better when/if you swap pulleys

gt40 heads and gt40 intake with a steeda cam. 42s with a 190 fuel pump?

Listen to Mike

I'm starting to see more and more blown combos on the tuning sites post about how their 42's are being pushed to and beyond their limit.

They have the hard data to back up those findings I might add
