Also have 5 digit number machine stamped o nthe crank at number 1 throw, with matching machine stamped number on sump mounting face adjacent- indicating block and crank have been matched , possibly by factory � any clues?
My car also has a totally non-GMH paint code on the plate � haven�t been able to track it � I�ll attach a photo � any help would be very much appreciated.
