(((I asked a similar question but got 2 bad answers out of 3. So here goes take 2.)))
I have a 1985 Ford F-150 with a 5.0 302 in it. I want to put in a Holley 4 barrel 600 cfm carb because i want some pretty good high performance for it. Heres what im gonna get besides the carb just to clear any contradictions:
-Intake Manifold for the carb to fit.
-Anything else i might need to make it a bit better, in time.
So thats what im gonna put in it because everything in the engine right now is stock and old.
SO MY QUESTION IS: If i get the Holley 4 barrel 600 cfm carb, will it kill more gas mileage than if i were to get a 2 barrel Holley 600 cfm carb? I am a decent driver, but i do love speed.
Plus, i can tune the carburetor so that it doesnt use as much gas right? Please help me!!! Thanks to all the answerers.
damn my bad, its automatic transmission.
