350 small block Chevy SBC 4 bolt main caps for 2 piece rear seal and ARP studs, nuts, and washers. These came from a running engine on a drag car. I didn't get out as much as I wanted so there are probably less than a 100 1/8 mile passes on the engine.  The bearings are in some of the pictures to so how little it was used. I left water in the block over the winter and it cracked. The new block I bought came with new studs, so I have no use for theses caps and studs. 

Like all main caps installed on a different block, these will have to be line honed with your block.
