It came out of a Sessna airplane

the thing is pretty big, runs on petrol or diesel, 2 spark plugs per cylinder, air cooled... naturally.
all logic tells me no, it couldn't be done and besides even if it did bolt up an airplane engine is geared up differently, no gearbox-direct drive to the prop (or road wheels

....and yet the other half of my brain is going: you knowwhat, with a can of WD-40, duck tape, and some cable ties i could get 'er to fit


what's the craziest thing people have seen and really work?
