S&S Cycle 450S Camshaft For Harley Big Twin 1948-1969

S&S Cycle 450S Camshaft

Forged through hundreds of brutal hours on the dyno, the asphalt, and the track, these S&S cams are dialed in to unleash unapologetic, raw power the second you twist the throttle. This isn’t off-the-shelf guesswork—it’s precision-engineered muscle built to dominate every mile of pavement you take on.

Features:

• A bolt-in hydraulic cam for 74" and 80" Shovelhead engines, made for earlier Panheads and Shovelheads
• The 450S can also be used as a low end torque cam in modified Shovelhead engines up to 88" with compression ratios of up to 8.5:1
• Although designed for use with hydraulic tappets, the S&S 450S can be used with solid lifters. Use with solids will result in more valve train noise, slightly higher cylinder pressure, and slightly more torque
• Good low and mid-range torque
• Recommend hydraulic lifters
• Made in the USA
