BEST CARBURETOR FOR STREET OR TRACK?

I don't want to start any argument. But this past season a racer local to me. Has won hundreds of Braket races through the years, as I have too. So his carb and mine are both well sorted out. His is a APD 750. It's on a 427 SBF he made two passes in his car. 1.28 sixty foot 5.91 @ 112 mph in the eighth. My carb is a 1040 pro systems 4150 style carb. I made two passes in my AMX. 1.32 at 60 feet 5.99 at 112 mph in the eighth. My engine is a 421 SBM. We swapped carbs made no adjustments to the carbs other than idle speed. We made two passes with the swapped carbs. He went 1.27 at 60 feet 5.87 @ 113 mph. I went 1.34 at 60 feet and 6.02 @ 111 mph.
I really don't know what that tells you other than his engine likes a bigger carb and mine doesn't like a smaller carb. We were just there on a test and tune day. Try to see what would happen if we swapped carbs. He did purchase a APD 1040 carb 4150 style carb. His car picked up an average of 5 hundreds with the new carb.
