carb cfm for 383

having a nice discussion w/ brothers regarding carb size on a fresh 383/4-speed...road runner cam, 9.5 compression, Eddy heads/intake for low rpm/torque/ 1.75 TTi headers/2.5" full exhaust with flowmasters.......coffee getter.

I say 650cfm AVS is just right...bolt it on and GO. Shoot, my 426 Hemi only runs on the rear 600cfm most of the time



they are lobbying for a 750....then play with the rods and jets. (I think they are just goona lean it down till it runs like a 650 except at WOT)

input appreciated....
