My machinist doesn't remember this block but I do. Each time I've had it in his shop, the cam bearing fitment has been an issue.
I rebuilt this engine in 2004, 2011 and 2022. I had to go back to my notebooks to confirm but each time there were 1 or 2 bearings that had to be installed from the back to go in right. This time, # 3 and #5 journals had a slight ridge at the front edge as if the boring bar didn't cut all the way through. When someone were to install a bearing, that ridge requires more force to press the bearing in place and it scrapes material off of the outside of it. Once past that ridge, the fit is loose due to having less material on the outer surface.
If I have learned anything from the engine threads on this forum, it is to have a solid plan for your engine build.The machinist was set to reinstall the new cam bearing tomorrow but delayed it a week since his son (Who lives in his house) tested Positive.
There goes another week.
I took the crank, rods, pistons, rings, pin retainers and rod bearings to another shop for balancing. The man asked why I chose to use heavier pistons as if I intentionally sought them out to make things more difficult and expensive. I had no idea of what the old pistons weighed nor how much the new ones are. I'm not a racer and the thought of the pistons being a different weight did not even enter my mind. I'll have to pay closer attention to stuff like this for other engines I build.
The balance job will take a week at the very least.
I can't move forward without having all the stuff here anyway.
Reminds me of a friend's story.If I have learned anything from the engine threads on this forum, it is to have a solid plan for your engine build.
