There is a category for both manifolds with the same carb.

So with the Performer RPM, 632 hp and 592 tq. With the Victor, 650 and 594 with the same 1000 cfm carburetor.

However, look at the average horsepower and torque.

Performer RPM - 521 hp and 552 torque.

Victor - 513 hp and 538 torque.

Now, which do you think would pose a better situation in a car that spends most of its time around 2500-3000 rpm?

At 3000 rpm, the Victor is making 284 hp and 497 lb-ft, where the Performer is making 305 hp and 533 lb-ft.

Another thing that the dyno does not show is throttle response....
