A 351W pumping out 300 RWHP through the air cleaner, through the mufflers, with a flat tappet hydraulic cam is nothing to be ashamed of. My 351W with air cleaner off and a CompCams hydraulic roller was putting out 325 RWHP, would like more but am not unhappy with performance.

Put a stroker kit in it, better heads and headers, and a hydraulic roller and your wishes should be fulfilled. This months Muscle Mustang & Fast Fords dynos a variety of 393W motors putting out 525 HP at the flywheel. Check it out.
