I just have a 'cheapish' digital caliper @ my shop but we do have a micrometer @ work. I just went & documented the bearings & races that were installed:

Inner bearing: Timken 387AS
Inner race : Timken 382A

Outer bearing: Timken LM 104949
Outer race : Timken LM 104911

The outer bearing/race assembly that I got from Oreilly's is National Bearing p/n A-38. I'm going to try & verify (cross reference) p/n's again now that I have the previous info in front of me.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
