Never say never........ but I’d be pretty surprised to see 745hp out of a 10.8:1 499 with std port Victors.

A very crude formula that’s based solely on flow shows a nearly 700rpm difference in peak between the 452 and 499, using 350cfm as the flow value.
It also shows the 452 peaking way higher than it actually did.
However....... it’s dead on with my old SR headed 451.
But then....... after the head and cam swap, it’s way off.
As with pretty much all that stuff...... sometimes it seems correct, other times not so much.

It’s not that I dont think that well ported std port victors are capable of making 750hp....... I just don’t know if I’d see that here on a 10.8cr 500” combo with a 265@.050 cam.
