A Magnum-series camshaft from COMP Cams, the grind offers notable gains over stock while remaining friendly to valve-train parts for higher-compression engines. It performs best with static compression of 9.5:1 or higher and a higher-stall torque converter. Ideal for 340 and 360 V8s with 9:1–9.5:1 compression, a 650–750 CFM carb and 3.55–3.91 gearing for strong high-rpm power without excessive wear.
