Moving on to engine assembly. some where towards the end of 2020.
After picking up then block from the machine shop where it was undergoing some basic clean up, and installing new cam bearings, I started putting parts together.
Its always a good idea to test fit and check throughout the process.
when I went to place the cam in block I noticed binding between one of the bearings and cam journals. After much frustration I discovered that the cam bearing bore in the block had a bur on it and when the bearing was driven it, it deformed the bearing radius cause the cam to bind on installation.
Its hard to see but this is where the bur was in the bore causing the bearing to deform.
This is just a pic for dramatics sake. I don't recall how many boxes of bearing sets and individual bearings I went through figuring this out! Plus I think I was already running oversized bearings on some boars. I don't recall for sure.

But eventually I figured it all out. I filled the bur down gently, bought the tool need for removing and driving in cam bearings my self, and continued on with the build.
