I have come across another hiccup with my 3.5 rebuild. The main bearing caps are no longer a interference fit in the block. I can just sit them straight in without any force at all. How much of a problem will this be?
Will an ARP stud kit be enough of a fix or do I trash the block altogether?

This will not be a big horsepower engine. My plan was just a freshen up with new rings bearings etc.
