Quote: the 950HP carb made 690 hp and the 1050 Dominator went 740 hp. Same motor, same dyno, same day, same intake, etc.
i'll have to try that test on the 446 i'll be testing here shortly. i dont expect to see anywhere near that much difference on the smaller motor.
when you ran the 440-2, did you use a spacer under the carb?? if not, then you're really comparing the big carb, with a 2" spacer, vs the small carb with no spacer.
some data: my 451 used 960cfm at 7500rpm, and my buddies 557 used 1050cfm at 7000...same carb, same manifold.
my motor peaked at 7300, his peaked at 6400.
at peak power, my motor used 953cfm, his used 1003cfm.
the bsac at peak hp, my motor = 6.23, his motor = 6.34 the bsac at peak tq, my motor = 5.61, his motor = 5.52
i did do the carb test on a 600hp 446 a year or so ago with std port SR heads and a Victor intake:
Victor with 2" Super Sucker and HP950 carb = 544.4 ft/lbs @ 5300, 608.0hp @ 6500
Victor with Moroso 2" adapter and 1050 carb = 546.0 ft/lbs @ 5100, 613.9hp @ 6500
Victor with Moroso 2" adapter and Pro-Systems 1080 carb = 549.6 ft/lbs @ 5200, 615.2hp @ 6500
