Thanks to all... crankshaft is in. Plastigauge says .002 to .003 inches. I think that is OK. A bit on the loose side, I think. Crank rotates freely. Now, how about that bearing in the flywheel end of the crank ? How easy is it to replace, and should I go to the trouble ? Looks like I would need a special tool to pull it out. I would call it a pilot bearing, but Haynes calls it a spigot.

Thanks for the quick and helpful responses.

There are two sizes. The small roller type in later cars, and the larger sealed ball bearing type in earlier cars. The best way to remove the bearing is with a bearing puller. Since you can easily take the crank out of the block it would be pretty easy to take it to a machine shop and have then do it at the counter. Most guys will do it for free, but they may charge. BTW, crank main being radial play allowance is: 0.030 to 0.070 mm (0.00118 to 0.002756 inches) so if you are closer to 0.002 inches than 0.003 inches your clearances are OK. Connecting rod bearing clearance is a bit tighter at 0.023 to 0.069 mm (0.0009 to 0.0027 inches). These numbers are from the factory repair manual.
