Cam bearing issue

So most likely that bore is a little tight or out of shape, line, etc. Just needs a little love next time before final assembly. Personally, I would try to ream by cutting an old cam to see if that cleans it up. Then you have a plan once the bearings are changed. I wouldn't mess with the bores unless it's really off line.

The blocks move around. Nothing you can do about that. AFAIK there are no oversized cam bearings out there for Chrysler stuff. You can’t hone the cam tunnel on a Chrysler because every bearing is a different size.

You can line bore the cam tunnel. But where will you get oversized cam bearings?????? Take a bearing scraper and carve some off the bearing until the cam turns freely and send it.
