575-HS: Bolt-in cams for 96, 103 and 110 inch engines with stock, unmodified heads. Great bolt-in upgrade for stock 96 or 110” engines; also works well in 96 to103” conversions. Lowers engine temperatures, increases torque and horsepower across the board, with emphasis on torque.
577-HS: The cam to use for 2007-up 103”and up conversion engines with flat-top pistons and stock or ported heads (bolt-in with stock conical springs). Provides smooth power without detonation. Broader timing for lower cranking compression and lower temperatures; great mid-range torque with strong top-end pull.
627-HS: Aggressive design for high output 103” engine conversions. Compliments ported heads, hi-flow throttle body, exhaust. Suggested static compression range 9.0 to 10.5:1. Broad torque curve, strong pull to 6,000+ RPM.
657-HS: 107” and Larger Engines. Max torque grind for ‘07up larger displacement engines with heavy payload. Narrower timing increases compression for more low-end grunt. Excellent valve train dynamics for long life. Works well with most bagger exhaust.
647-HS: 113” and larger engines. Max power grind for ‘07up larger displacement engines. Broader timing for higher compression applications. Great valve train dynamics for long life. Compliments high flow heads, intake and exhaust.
