A little tight, not too bad, I'd run 5W-30.

If this is Plastigage, don't believe it. About all that will tell you, is it looks like you at least have the right bearings.

What's the crank diameters, measured with a micrometer?

Don't have a mic. Just turned 10 from a reputable machine shop who did the rods too.

Spins nicely?!
