I usually one of the following main bearings: FM 125M, Clevite MS1010H (for aftermarket block or with tangs sanded off for factory block), Calico coated King MB559AM. Obviously, if you need a "ground" version of those, then you would add that to the end of the bearing: FM125M10, MS1010H10, etc.
For rod bearings, I use: FM 8-7200CH, Clevite CB743HN, or Calico coated Clevite CB743HN. Same thing applies to rod bearings with sizing.
As mentioned above, always check rod bearing to crank fillet clearance. Check it every time, don't take anything for granted, even if it's the same combo you've used 100 times.
The part number for a SBC rod bearing is completely different and they do not interchange as the journal sizes are different. A 2.100" journal SBC uses something like a CB663HN and a 2.000" rod journal uses something like a CB745HN.
