L48 vs. L82 block casting number
I was told that if you have an engine block number that ends in 010 that it means that the engine block is a four bolt main. I have a 75 with a L48 engine two bolt main but my engine block number ends in 010. Does anyone know about this?

I think that is a urban legend. Your vin tells you if it is a L-48 or L-84 as does the block. CKC for a L-82 auto and I believe CKX for a L-48 auto. The L-82 was a 4 bolt main, the L-48 a 2 bolt main.

right, the 010 was used on just about any GM car with a 350...........
