headers/cam/intake

I'm putting in a E303 cam, gt40x heads and bbk shorty equal length headers. My question is do I need to Chang out the fuel system and how much HP will just this combo give me????

Yes, you will need a minimum of 24# injectors with matching maf. Hard to determine any gains without knowing any other mods.

+1


I would WAG 250 to maybe 300 HP max if you use the correct MAF, injectors, & TB. Maybe on the low side of that if you still have the stock intake.

I'm sure Trojan will agree, go with the abaco maf, it's programmable for any combination and more accurate than most other units.
