As far as bearings, I use Clevite 77 on a hardened, stock (not reground), or nitrided crank. I use aluminum bearings on a crank that has been ground and not re-hardened or nitrided.
Glad to see someone besides me likes to have decent hot idle oil pressure. I've been getting getting burned at the stake for using HV oil pumps, but it really makes a difference in bearing wear, especially when you'll be running it at low rpm (like a street car).
I also use King bearings exclusively now, nothing against Clevite, I just think King is better.
