Just bought this and don''t know much about it. It has a number of Model T parts with a Chevy transmission and a truck ruckstall rear end. Runs great! Jeep engine, but not sure which.
I'm seeing a flathead so, without better pictures, I'd guess it's the WILLYS 4-cylinder motor that was in the Whippit in the 30's and which made it's name as the powerplant for the legendary WWII Jeep.
Never thought the little 4-banger would be overkill but that's alot of power for a lawn tractor.
