If you're into Pontiacs, there is no need for me to explain what a SD421 is, or how rare they are. This particular engine is rather unique even as SD421's go. It was built in late 1962 or early 1963 in Dearborn Heights Michigan, as a 495 cid stroker, (4.185 bore x 4.5 stroke). (Factory 421 was 4.09375 x 4.0").
