Hi, I just joined Team Buick. Cool site. Glad to be here. I have a 1936 Century ready to restore. I'm not sure of the engine ID. The block numbers are on the right rear. It says: GM, then below that is 1288737-1 and below that is 6-20. The engine number books I have do not come close to these numbers. Can anyone help me out? I'd really appreciate it.
