No need to go to the gmc site, many of the same guys are here, some just lurk, but they are here. The engine you have is a 235 Chevrolet, so mechanically there are many guys on this site that can help. Find the casting numbers on the block and they can be identified for you. Many parts are interchangeable between the GMC and the Chevrolet. Good luck!
So if I have a Chevrolet engine in it does anyone know what engine it came stock with and what are the odds of finding one?
