I'm curious about my engine. It looks just like the engine in VirginiaFireTruck's Thalia resto, and I don't think it is a 216, but I can't find any information about any other engine being used in trucks in 1951.
As close as I can tell the engine serial number is: IOI8359 F54X. The truck has the 0 - 30 psi oil pressure gauge. There should be a couple of pictures of the engine in the set I posted on Webphotos. (link above.)
Does anyone have any ideas?
