How much cfm. can a Built 440 take?
My girlfriends Dad has a BUILT 440 in a sleeper 383/727 car. The 440 is .30 over forged internals, balanced and blue printed, ported and polished. It has a 850 cfm Holley Eliminator on top of a Edelbrock intake. Some one told me this engine currently at 500 hp. could take as much as 1100 cfm!!!!

Guy at speed shop said only 850 cfm?
The guy at the speed shop I just went to said that for street use he did not think the 440 bored .030 over, stroked and cam, would take more than 850 cfm?

Diminutive Lid,
I don't have the #'s off the top, but I believe a stock 6 pack car has total carb cfm in excess of 900+ cfm. I'm running 850 Edelbrock Performer on a mild 440. Depending on heads and exhaust, I'd bet you could easily run 850.

Well just got a B/RB Mopar performance block book for X-mas said the stock six pack was 1200 CFM!! Then my fiences Dad's should be able to take a dual quad set-up right?
