S&S Cycle 450S Camshaft for Big Twin with Stock Valve Train

• 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
