As long as I have the block out of the car, and I am making a big mess drilling and chamfering oil galleys, why don't I machine a groove behind the cam bearing instead of buying a cam bearing that has been cut in a lathe? It seems simpler and stronger to me.o No: Jay get ready.. I have a lot more questions.
We were doing just that years ago,but with TA's back grooved bearings its not necessary,and it works great.Also while we're on cam bearings,if you could afford the teflon coated ones they are the best. gary
I'll second that. We also used to groove the block and then reclock the bearing after drilling a smaller hole to get the oil entering the journal in the correct spot. But the new TA backgrooved bearings are a lot simpler and have the smaller holes in the right spot already. You won't have any issues with bearing loads by the grooves on the backside.
