Thanks for the detailed reply and for the link.
Yes, that's correct -2.0L 911S 66mm counterweighted crank.
Your conclusions are the same as mine. I just wanted to be sure that:
a.) .001" undersize rod bearings didn't recently become available and
b.) that current conventional wisdom doesn't recommend that a short-stroke motor for a track car, with oil system updates, should run looser clearance on the rod bearings.
I'm going to recalibrate my Mitutoyo .00005" mic and re-check those measurements then have a chat with the machine shop Monday. I can't imagine why they would grind or polish the crank to some random undersize dimension for which no bearings are available. That certainly was never my instruction. I authorized them to do everything they recommended to check and update the crank.
Thanks again.
