Help me settle an argument

Over the years, the numbers I found on 10-12 second 360's is that a 750 double pumper will be about a tenth faster than a 650 double pumper or 750 vacuum secondaty Holley "IF" they are tuned/optimized to the same level. Of course, there are a lot of little variables. But not 2 tenths worth unless the tune-up is off on one.

Bigger carbs could pick up a bit more, but can also be harder to find the tune-up. Double pumpers like more gear and converter (or 4 speed) but are harder to tune/coordinate the squirters and pump cams. But they can ET and MPH better than same sized vacuum if done right. Using a 750 DP, I can pull high 1.40 60' times running an IHRA Stock class 360 crate motor in the 11.20's at 116-117. Car weighs over 3,530 with unported heads and a hydraulic .474" cam. But I have a lot of gear, converter and cam duration. But there are other IHRA and NHRA class cars that do even better with similar combos.
