I think it's a "find"!
If you could get the whole thing, that would be the way to go. I think most of these engines had a compressor for the air brakes, but for sure what you have is the post WWII "Big Six". I'm sure it's heavy and large but also incredibly strong. It would take a bit of radical surgery to fit it anything "normal" but it would sure cause a crowd to collect. With minor tweaks, you would have about 250 Hp and tons of torque! I'd love to have that thing and I'm sure other inliners would as well. My problem is that I am just today making an offer on a house we want to move to, and the garage needs work (built 1929) so it will be months before I'm back to cars.
