Like above.

Way back when people thought they where cool if the had a "Holley 750 Double Pumper" on their street car.

Problem was, for 20yrs or so, the average 'performance' street car had a piece of schit factory 180-200HP 5.7L motor.

That was where the 'over carbureted' term mostly came from.

According to that calculator I need a 1031cfm carb. Thats good news , I was going to buy 4 and now I only need a single 1050cfm carb per motor.
That saves me a ton!

change out the center body to an HP style such as the holley one and see an easy 20+hp gain.

And if you send it to Dean Nickerson and he tootsie rolls the top of the carb for $900 it will make another 25hp on top of that!
