What is everyone using and why?
Who makes the best bearings?
Does anyone use any coatings?

I use Clevite 77 race bearings with the Calico Coating. I just took the engine apart to inspect everything after 100 passes and the bearings look brand new.

What about coatings. Is anyone else using them?

King bearings are what I like to use, these hold up great (World of Outlaw, truck pulling, NOS engines).
Not coated either.

Clevite, Fed. Mog., King..... bla bla bla.... they're all good. I've used them all with good results.
Much is more dependant on sizing, and journal/bearing finish than on the manuf. of the bearing.

I have a few.....
I was talking to another shop owner just a few weeks ago about rod diameter. He told me he sizes all his rods at the bottom or a few tenths under size... his reason was that it will keep the bearing form spining, due to more crush... I dis-agreed with him. I said the rods as well as the mains have a bore tolerance for a reason. If the rod is within the tolerance no matter if it's on the high side ( but not over) the bearing will be held in place, with no fear of spinning..... I have sized rods on the small and big size to adjust my oil clearance and i never had any issues with them... It' sbeen a year or so but i did maesure the crush on time and i think it was like .005 per bearing shell.......
What is the correct way to determine the correct oil clearance for rods???? In the clevite book almost all engines have a minimum of .0005 for oil clearance.... I don't think a engine would live long with .0005 oil clearance on the rods????? would a bearing with a larger amount of eccentricity like a smaller oil clearance???? say you would build a engine with .0005 clearance on the rods would there be enough oil passing over the bearing to keep it cool????
