The Stovebolt Site Forums The Shop Area General Truck Talk pontiac engines in GMC trucks

I have a 1928 GMC 1-ton that has a split flathead straight 6 engine. I believe the displacement is 186.5 As far as I know, this engine was only used in 1928-29. There was also a Buick OHV straight 6 engine that was used, but I'm not sure of the dates. I think it was pre-1928.
