What oil pump/bypass spring, and oil restrictors?
I've struggled with a few BBC with billet pumps that just moved too much oil upstairs for the pan volume.
We had that issue w/ a Dart block small block a several years ago. We tried a billet Melling oil pump and it pumped way too much oil up top...starved the bearings. Went back to a regular HV pump and no more issues.
