Some would say so
the large primary 440 ones were factory rated 850cfm. But the 1.5s were not far behind. I don't care which one I bolt on, or what I bolt it onto. It's the moan that does it for me,lol. Sweetest sound in the history of the world,lol.
And back in the day,NHRA rated 340s with TQs 15 hp higher than the AVSs they replaced, which IIRC were rated at 580cfm.
But just look at that big TQ. It looks mean just sitting on the shelf. It's calling, calling; "try me,I dare you". It's got BIG personality. And then when you set it on the intake, ATTITUDE. And then when it's sitting on the engine, it's melt-my-heart BEE-U-T-FUL! And then when you finally start her up and tickle the go-pedal, that's when she comes alive; HO-LEE...........
