Whats the difference ? 4150 question !

Our old 950HP 1.375 x 1.750 billet plated (830cfm) carb pulled 2.0hg@6000 on the dyno, it flows around a calculated 967cfm on our motor in the traps@6200rpm on a 4.565 bore x 4.500 stroke motor, a 1050 dominator w/adapter was also tried on the dyno and made only 3hp more, it pulled .07hg, we have the big 440-2 Indy on it, just as an example, putting even a well tuned 1050 dom on ours would perhaps gain us a 10th and some mph with our current combo, the thinking that all mopars like a big carb is not always true as I thought it was, the whole combo/rpm is what to look at in picking a carb not just engine size. Now if we had 12.5:1, a 750 roller and 5000 stall with 4.56 gears and turned 7500rpm then yes an 1150 dom would be the choice on a 440-3 intake.
