Need more info... intake? heads? other mods?

thats it
stock heads
not sure which intake im going with either

I wouldn't go bigger than a 650 cfm carb on that one but this is a matter of big debate. You will probably get opinions from 300 cfm to an 1150 dominator. The intake choice will be a big topic as well. I'd go with an Air Gap intake but you really need some headwork, good headers to go with that cam.

yea
i bought the car that way though
i wouldnt have picked that cam had it been my choice
one day ill put a comp cam in it but its not a big priority this very moment

Stock heads and an F303 is a mismatch anyway. You're either gonna need a somewhat smaller carb or one that pulls good signal, so you don't lose bottom end. Top side is gonna get strangled by the heads before the carb.

pull the F and go with a E put on a 600 holley.it will fly
