Don't know much about it KK, there are at least 20 pistons, I've not been on site yet,picture is of my nephew he's over 6ft. I suggested he acquires a couple of pistons for stools or coffee tables, I don't know if its a v or possibly a tri,like a deltic(sub engine) or maybe a gas pumping unit, its big for sure.
Finally, an engine capable of tearing the rear end apart on a Fordson Major. ... I bet that engine was in the two or three thousand + HP range. But, there has to be a reason that it is apart and in that dumpster. Dave!
