Max horsepower with EQ heads?

Coffee&Cars said
Maybe this will help, from Muscle Motors...... .257 x no. of cylinders x flow @ 28"
example-- .257 x 8 x 410 = 843 hp.

And maybe this will help further.......

As far as flow goes yes--I built a 469 ci with Edelbrocks(298.5 cfm) = 680 hp =2.278 hp/cfm. J.Rob

My 451 stroker with Edelbrock RPM heads flowing 349 cfm made 787 HP for 2.255 hp/cfm. My 500 wedge made 848 with 370 cfm for 2.292 hp/cfm.

Your formula says he will only make 614 HP and I can only get 718 & 761. I like the way he and I calculate it.
