As Denny W. noted the 750 will give you more top end power.However I think you will also see a decrease in throttle responce with the bigger carb.Also with the 750 you you will be dealing with mechanical secondaries witch also has an effect on street drivabilities.I would give it a shot anyways,You might like it.

If you take it to 6500 than Id say you could use a little more than what you have, personally Id use a 670 Holley Street Avenger. You could also install a 1" open spacer under the carb to increase plenum volume , has simialer effect to installing a slightly larger carb(doesnt always work that way though ). personally I think 750 is a bit much.75 GMC C-15 factory 454, automatic, lowered
Sorry for the Hijack, Hotrod46!! My real reason for the post was to see if you'd checked Crutchfield, not to divert your build thread. My bad....
