I ran across this adapter at the parts store and was wondering if anyone knew the logic behind adapting a 4bbl carb to fit on a 2bbl intake. My thought on this is that a 4bbl carb gets better fuel mileage than the 2bbl because of the jet sizes in the main ports. I have always heard this to be true as long as one keeps thier food out of it. Let me know what you think.

If you want a 4bbl spend the money on a new intake.
