As far as oil pumps go, I always take them apart before brazing the pickup to the pump. Also, I take the spring out and replace it with the Corvette spring. I get 60 psi at hot idle and no fluctuation (because of the big block pump having more flutes on the gears). The big block pump also is equal to the small block high volume pump.
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.
