The block was decked square, bored and diamond honed .020, New cam bearings, etc.
A fresh factory forged crankshaft was scrounged up due to the old one being a welded on remanufactured piece of questionable quality.
I assembled the shortblock with fairly tight bearing clearances, wanting to use a modern thinner oil .
Rings were file fit , 1/16, 1/16, 3/16 with moly tops and a Napier cut scraper second and installed on Eagle H beam rods
