If you have a stock long block and are wanting some seriously rowdy Camshafts, look no further! These Comp Cams Mutha Thumpr Camshafts have a very aggressive idle and offer good power gains in the mid to upper RPM Range. 3.73 Gears and 2800 - 3200 Stall suggested. No Springs required, but they do require Comp Cams Phaser Limiter Kit.
