427 Side-oiler - approx. horsepower?

So all other things being equal, what affect do you think adding two 4-barrels in place of a single 750 would have on the same 450 HP side oiler?

Two four barrels will give you more horsepower, but you lose the benefit of the center hung floats. You also lose the beautiful Turkey Pan.

All a twin set of 750's does is try to rev higher, the pursuit was horsepower. It worked. I'll take the juice over the aesthetics.

Um, don't you typically use a pair of 450s?

Actually 600s, they were used a lot on Shelby's Mustangs .. and maybe the 428 and a few 427 Cobras. The BC-BDs (715 cfms) made it into the comp 427s. Carl's Ford has an exclusive deal with Holley and they continue to manufacture exacts copies of the BK-BJs and the BC-BDs expressly for Carl's Ford. I almost went with a set intead of having Quickfuel build me a pair of tricked out 750s.

Correct @ 600 cfm. I just bought a pair, Merry Christmas to me.

I am quite comfortable that the engine dyno work I paid for was accurate. No doubt a set of worked Edelbrock heads would flow and perform better. But I wouldn't trade my virgin MR heads for a set of stock Edelbrocks.
