MORE ON CAM GEAR CLEARANCING
I recently read a Shop Solution about using a cam and cam gear to test for gear to block clearance on late small block Chevy blocks. Well, here is our tool I’ve used for years. It’s an aluminum hub that’s .002 under cam bearing bore size so a guy can do it when the block is stripped and cleaned. We turned down the scrap aluminum in our shop on the lathe, where it was also drilled and tapped. This can save you from damaging a new cam bearing and it is much easier to handle than a gear with the camshaft hanging off of it.
