    trying to identify engine

    I have a 56 Roadmaster 73 made in Flint with what appears to be a 322 nailhead engine. The engine serial number is I9649237, the first digit is I as in Idaho. Since this number does not start with V146..... I am assuming this is not the original engine. The casting number on the left head is 1168930, which is for a 56 322 nailhead. What is this engine????

    That first number is a 1 and not an I. Therefore your engine number is 19649237. The last number, 7, denotes model 70 Roadmaster.

    Thanks for the reply. So would you say this is the original 322? The info I have found so far says there should be a "V" as the first digit.
