Agreed, is it just a waste of fuel, or a matter of not using a WOT, or would it bogg to engine down. I wouldn't be asking if the engine had not had the heads, headers, digital ignition, cam all added. 650 to 750 would be my choice for a stock hp 383. Knowing 2 quads sharing 1200 cfm is probably only equivalent to a 900-950 single 4 barrel, leaves me with the question. Do I have a chance with two 600's? Can I re-jet them any to make them work? Am I just wasting my time?
