S&S Cycle 450S Camshaft

Features:

• A bolt-in hydraulic cam for 74" and 80" shovelhead engines 1966-79 and 1983-84 (Can be used in 1981-82 models if cylinder heads are updated to late style valve guides.)
• 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 solid tappets will result in more valve train noise, slightly higher cylinder pressure, and slightly more torque
• 1500-4500 rpm
