I've been trying to find an aftermarket block for my 55 chevy which runs in SS/O. According to their online acceptable parts list the Gm replacement block is suppose to be 10051183 which does not show up in a search on gmperformanceparts.
I did find the specs on this block and it seems to be a 2 bolt main 1pc rear main seal, and from what I've seen its been discontinued.

What Id like to have is a 4 bolt main block with a 2 pc seal.
