My truck is a 1965 GMC shortbox fleetside built in Oshawa by GM of Canada. It's Woodland Green in colour and was ordered with the bull low 4-speed and trailing arm/coil spring suspension. My dad was told in the late 70's when he bought the truck that it was a 250, I decided to verify this using the casting number. My number is 3850817 which lists as being a 230 or 250!
Is there any other way to get a positive I.D.? I do have the engine apart if that helps.
