Note: With any hydraulic camshaft larger than our 1523AL/BL grind, we strongly encourage using adjustable rocker arms. The stock stamped rockers do not have a true 1.5:1 ratio. They will check somewhere between 1.38:1 and 1.45:1 ratio. This will yield a loss of lift (up to .045"), 2°/3° duration loss and also slow the rate-of-lift resulting in a possible 25HP loss. Any camshaft using double valve springs must use adjustable rocker arms to prevent damage when the stock rocker arms break.

Power Ranges: These are the "sweet spot" in the power range. Generally we suggest shifting at 300-500 RPM above the "sweet spot" for the best ET's.

Spring Warning: Our camshafts are not comparable to other manufacturers and require special valve spring pressures to operate and live satisfactorily. ONLY USE springs meeting the specifications listed here or on the provided cam cards. Valve spring pressures and installed heights are supplied with each camshaft.

Caution: Minimum piston-to-valve clearance is .060" intake and .100" exhaust. If your clearance is not adequate, we have tooling to cut deeper valve reliefs. Check our tooling section or call us. Maximum lift with stock guide height is 0.450", more lift requires shortening the valve guides.
