You want track proven? I've posted this so many times now that I'm sick of it but here goes. All steel '81 Camaro w/0.030" over 455 Pontiac, ported 6X, Performer intake, cam, TH400, 3.08 rear gears- 12.7 @ 107 mph. Carb was a Holley 4777. Picked up almost 2 tenths by changing to 3.31's.

Would his car pick up using a bigger carb? Possibly. But not by enough to compensate for the amount of missing performance- especially the lack of 60' time. A smaller carb could even help the 60' time.

I'm waiting to see what happens w/the new TC.
