I think it's around 750 isn't it? Same as the old quadrajets from the late 70's and early 80's only with computer controls for idle mixture and emissions.

Yep they are huge, upto 780cfm+ but are usually restricted down to flow less. Gotta love those huge secondaries.

More like 650-690 I think. You can measure it, the bores are not the same. My Buick 455 has a 795 Quad on it, and the cc Quad doesn't look the same to me in the bores.
