crossdrilleed or not?
Howdy All!
I am currently putting together a 1958 ford f100 and i am having some trouble witht he cam. I have bought two sets of cam bearings and the cam is TIGHT when I put it in. I've had the cam redone and it is within specs. I have looked through some old books and have found cam bearings for a crossdrilled cam. Can anyone tell me how do I tell if it is crossdrilled or not? thanks.

A cross drilled cam means it has holes drilled in the journal at 90 degree angles for oiling to the rocker arm shaft. A better choice from later years is a grooved journal cam. Instead of holes drilled, it has a groove all the way around the journal. This was a change made by Ford around 1958. You must use the proper cam bearings for the type of cam you have for proper oiling of the rocker shaft. If the cam is tight you may need to ream the bearings.
