For the move from the stock engine's flat-top pistons to the supercharger-compliant, dished slugs in the SuperMOD stroker, AFM's N-22 camshaft had to be replaced with a pair of N-52 bumpsticks. The new cams are designed to work well in engines with aftermarket pistons, and Trick Flow or ported PI heads. The N-52s are healthy and don't like driving under 2,400 rpm, according to Rick Anderson. As the cams' rev range (3,500-7,200) is about 1,000-rpm higher than that of the N-22 camshafts (2,400-6,200 rpm), 4.30 or even 4.57 gears are perfect for great street performance with this type of engine.
