Item Details
  • These camshafts are designed for performance upgrades in Panhead and Shovelheads engines with stock valve train; stock style tappets, pushrods and rocker arms
  • It is important to differentiate these cams from cams for use with the S&S hydroulic valve train upgrade kit, retro conversion or replacement cylinder head kit for Panheads which use 84-99 style cams
  • These cams are high lift with the exception of the 450S and require lift valve springs and clearance checks for installation
  • Bolt-in hydraulic cam for 74in. and 80in. Shovelhead engines 66-79 and 83-84 (can be used in 81-82 models if cylinder heads are updated to late style valve guides)
  • Can also be used as a low end torque cam in modified Shovelhead engines up to 88in. with compression ratios of up to 8:5.1
  • Although designed for use with hydraulic tappets, the 450S can also be used with solid lifters. Use solids will result in more valve train noise, slightly higher cylinder pressure and slightly more torque
