I picked up a 3963512 4 bolt standard bore block with the original L88 pistons still in it and has a 6223 steel crankshaft not a 7115. The block has a casting date of L-3-9 stamped CE0XXXXX and assembly date of February of 1970. Can this be correct with that crankshaft and being a L88 warranty counter exchange? I have been told the guts were never out of the motor since installed from Tonawanda.
