Oil clearances and a surprise

I'd not worry over that 1 tighter main bearing, but if I did, a bit of crank polish will do. I've polished almost .001" with no issues. And since the full groove mains ought to use more oil, then I would want less mains clearance. For an engine of this power, IMHO few .0001" is not going to change anything.
I was wondering about that. I'll have a talk with the new machinist tomorrow. It would be nice to start assembling it soon. It'll also be nice when I get the pistons and rods back so I can start my rod bearing clearance checks. I'll try to organize the bearing shells so that the clearances are at least above .002" maybe .0021" like the first mock-up.
