504 build

Hey guys my 504 is close to your builds with a small difference. 9.8 to 1 comp with 660 lift 270 dur flat tapped cam Eddy heads (96cc) chamber heads fully ported Mad ported and victor intake alky injected (terminator). in my 2820 mustang was going 5.82-5 @117 MPH and 9.20's at 146+ MPH
with a average 60' 1.27....
Wallace calculators says 710 HP.. Good luck and you should have know problem making 750+

looks like a good combo.if the heads work as good as the flow numbers are.750 hp should be no problem.
