Hi again Dodge Gurus/Boffins, I am rebuilding an engine that I believe to have come out of a 1950 Dodge 6 Custom. Engine number reads D34-67930 (although the 6 and the 9 both have straight backs and I have seen stampings on other blocks with a straight backed 5 that looks like a 6 with a hat on) -- Anyhow what I need to know - Is it common or normal to have a five digit engine number ?? most others I have seen have six (after the model Prefix). Any help/advice/comments more than welcome. Thanks again in advance, B.B.
