    700-800hp is do-able with a solid roller and the right combination.

    Ok. Maybe I Think My Thread Should Have Said:does Pump Gas,roller Cam(solid Or Hyd.) Go In The Same Breath? (with 496) . I Don't Know, Seems Like All The Roller Cams Call 4 High Compressions Ratio's.

    OEM production engines have been running roller cams for years now.

    Steel is corect with the hp numbers although you probably wont find anyone hear that will be willing to give up their 496/800hp combo if they build engines professionaly. However, 650 hp is totaly do able. 10 to 1 AFR 305 w/cnc chamber, hyd. flat 246/254 @ .050 (crane) single plane dart and a 850 carb. If you must have a solid flat, get something around 254/260 @ .050 to get the same lobe area. Need more, step up to a solid roller 254/260 or so @ .050 and run the larger AFR325 with cnc chamber add some compression (cut head .075" and go to a possitive deck height .006 out of the hole) now your 10.5 to 1. Go to a dominator 1050 and some spacers and you will be knocking on 700 hp at 6500rpm. I stop here!
