Well after some mild weather and a bit of rain I got out to take a look at what was in Jed the truck for an engine and it is truly a flat head 6 but it is not a GM it is a diamond reo which makes it an International which for me is great as I happen to have a 1941 International T6 that happens to have a need for a new motor so I can see a dozer getting a new life some time this year.I think that I will put a small 8 in the 53 and the 53s drive train into jed if I get lucky I might even get in some fishing .I am going to enjoy seeing how that old fella married a diamond reo engine to a GM tranny . Just to back water here it goes to show you can't fool men that work on these trucks for love it appears that chev did not make a flat head engine but now I can put a good old piece of construction machinery back in service.
