Ihaven't had the oil pan off and was wandering do L48's have 2 or 4 bolt mains.
2 except in rare cases when GM ran out of 2 bolt blocks and substituted 4 - Ive heard that story though never seen an L-48 original motor with 4 bolts.
BTW Nothng wrong with 2 bolts in street and even mild race applications 0 they are plenty strong.

Agree - L-48 engines should have all been 2-bolts, and I have seen them built up to 400 HP with no problems.
