This is a complete engine trans combo from the fan to the ujoint. Carb to bottom of oilpan. Was pulled from a car some 50 to 60 years ago. Not locked up. In fact, the cyl. bores are stock diameter with little to zero ridges at the top. Even has the factory dual disc clutch. The factory vacuum fuel pump and much more. I'm going to be so bold that I claim this to be a low mileage original. My plan was to disassemble it, clean up the innerds and then reassemble with assembly lube, and run it. The aluminum crankcase and cast iron cylinders are clean and don't appear to ever have been oily or greasy. There is so much more that I'd like to say about this, but an interested party would have to contact me for more. PM or call/text to 630 five 6 seven 8000 The syncro trans with pto driven mini air compressor is worth 1800 alone
