Well, thanks guys. That did the trick. By looking up the additional numbers it turned out to be a '56 235 with a block date casting code 4 23 6 which would make it April 23, 1956. And that cannister solves my oil filter question which was bound to come up sooner or later. Thanks a lot. You're a great bunch.
