alright in my budget 351 build i need a flat tappet cam because i cant justify dropping the cash on retro rollers while i'm still using gt40 heads. i need to know which ones i can use while still being efi. i want to keep the rpms low and i want as much grunt as i can get out of this motor in the low to mid rpm range.
