If you're leery about it, replace the bolts, and get the upgraded ones. Now would be the time to do that if you're having the rods sized.

I agree, top bearing half looks beaten from det. It's possible it's from being out of round, if the rods weren't originally sized/checked, but personally, I would replace the bolts, have them sized, and the crank checked too.

If you are going internally balanced, don't forget you need a neutral balancer, and would recommend an SFI one (if you don't already have one).

I use a pb1056ss. Internal balance it says. I put it on about 3-4 years ago, replacing the original balancer. The engine was originally balanced with the OEM balancer. When I put this on, I really wasn’t thinking of the balance, but it didn’t seem to affect it all.. sounds like a good idea if I get into this motor, which I probably will is to upgrade and replace the rod bolts. I find it odd that I don’t see any markings on these connecting rods at all saying a part number or a company. Or something.
