mbaird,
If you like to experiment, try a pair of 44 IDF Webers mounted on a 1/2" adapter plate.
I did this on a 455 Pontiac that I tune. I am not sure which intake we had on with the Webers, because we were playing with three different intakes at the time [ Victor, factory HO, RPM ]. With an 850 TQ, & a/f optimised on the dyno, the Webers picked up 30 rwhp, with no other changes. Ran 11.58 @ 118. Street driven car, 850 rpm idle, Turbo 400, 3900 lb without driver, 3.31 axle.
