engine combo

been doing alot of bench racing and came up with a combo id like to put together over the next winter and this is what im thinking...
5.9 magnum block bored 30 over
hughes forged 426 stroker kit
hughes ported iron ram heads, flow 268 at 500 and 264 at 550
hughes ported airgap intake
proform race vacume secondary 750 carb
not sure how big of a cam im going to run but it is a street car so i think around 550 lift. or wht if i swaped to a mechanical roller cam and really made some horsepower? how much horse do you guys see coming from this combo and what would it run in my 3250 pound cuda with 727 8 3/4 with 3.73's. right now it has a flat tappet stock stroker 360 going 13.3 on 9 inch slicks
