I have an engine which I am desperately trying to identify. It is marked as GM3898948 but I can't seem to get definitive information on it. It was in my husband's 1960 Chevrolet Corvette. Can someone please help me or point me in the right direction. I am trying to identify it so I can sell the motor (which was already redone once, but unfortunately, no prepped for storage, so some rusting occurred).
