.0015 on Rods Too Tight 408?

It's on the tight side, but if you break-in it in easy and then go to full synthetic, it'll be fine. I would also check the side clearance as part of making this judgement; a really loose side clearance will lower the pressure in that bearing, and make the tighter clerance more critical, and if that were the case, I would make more of an effort to clearance it more.

Also, it would not take much to polish down a couple of journals a few .0001 more.
