Camshaft Specs: The duration at lash point in degrees (intake/exhaust) is 279/287; duration at .050" tappet lift (intake/exhaust) is 218/228; and maximum lift with 1.6 rocker ratio (intake/exhaust) is 525/525. Valve lash is zero/zero and lobe centerline is 112 degrees.
Technical Notes: The LT4 camshaft 809-24502586 was designed to be used in a number of different engines. Therefore, the following change may need to be made to allow for correct assembly of the engine: For LT1 and L98 engines 1995 and before, the dowel pin in the end of the camshaft must be pushed in so extension from end of cam is .30+/-.01", the same as the production part. For 1996 LT1 and LT4 engines, the dowel pin is in the correct position, extending .620" from the end of the camshaft. This camshaft has a fuel pump lobe.

Aggressive-Performance Cams

The camshaft is one of the most important factors in determining an engine's overall performance profile and capability. Chevrolet Performance precision-engineered Hydraulic Roller Camshafts are extensively tested and available for popular GM small block, big block and LS-series engines. To avoid possible engine damage, a distributor with a melonized steel gear must be used with steel camshafts.
