PROBLEM, is that i know the cam bearings are 1. 868 ID, but what is the OD of these bearing, also the width, do they have oiling holes or do they only use spash. I have an EDM hole popper, so i can put in a small hole for oiling to the bearings, i can also run a rail oiling system to the rockers located below the cam.
I guess my main question is what size are the cam bearins OD and ID, plus the width.
Thanks in advance Carl.

A 1.868 would be a stock SBC cam journal and the roller bearings I can't remember the P/N is but any how the housing bore we machine the block to is 2.250. And they do offer a wide and a narrow bearing.
Check with CV Products as theu have them in stock.
Hope this has helped!!
