When were the rubber rear main seals first available? I bought a long block last week and got around to pulling it apart today. The engine was very clean, but froze up tight. The block is a EDB with 113 heads and appears to never had any paint on it. I pulled the heads and wow, except for minor rust in two cyl's they look new, never cut and the orginal fomoco valves are sitting high on the seats. I checked the bore and it is std bore. I got all of the pistons out except # 6, letting it soak overnight. I then pulled the rear seal retainer and was supprised to find a rubber seal. When I got the crank out it is std/std. I understand that the EDB block was a one year only 57 292 block. I am thinking that this was perhaps a factory service long block since all the parts appear to have been new when it was assenbled. The only think that is throwing a kink in that theory is the rubber rear main seal, however it did have steel shim head gaskets.
