Theduration figures in the shaded area are taken at 0.050" tappet lift. This is useful to checkthe cam with a degree wheel during installation. The solid color is advertised duration. Forcomparison purposes, add intake and exhaust lobe centers and divide by 2 to calculate“camshaft lobe separation” specification for Ford Racing camshafts.NOTES :➀ On EFI engines, performance camshafts work only with mass air inductionsystems. Will not work with Explorer EEC-V EFI.➁ Also fits 1994-1997 351W with factory roller cam when used with mass air EFI.➂ Stock 5.0L HO cam advertised specs are 266°/266° duration, 0.444"/0.444" lift.➃ May require piston modification for piston-to-valve clearance. Valve clearanceshould be checked.➄ May require longer push rods.➅ Hi-Stall torque converter recommended for automatic trans.➆ Emissions legal with 5-speed manual trans. E.O. #D-225-16.➇ Great for superchargers. Manual transmission recommended.➈ Good torque and power up to 6200 rpm. Manual transmission recommended.➉ Good torque and power up to 6500 rpm.
