ABOUT THE LT4 CAMSHAFT: The LT4 camshaft P/N 24502586 was designed to be used in many different engines. The following change may be necessary for correct engine assembly: For LT1 and L98 engines (pre-1996) the dowel pin in the end of the camshaft must be pushed in so extension from end of cam is .30+/- .01. For 1996 LT1 and LT4 engines, the dowel pin is in the correct position extending .620 from the end of the camshaft. This cam has a fuel pump lobe.
