Guys, here are some photos of the little Saito "jug". After tearing down this brand-new engine, I am more convinced than ever that this project is very possible, and will result in a dynamite radial. Small model radials are basically unavailable... commercial model radials tend to be pretty big. I'd estimate that a finished 7 or 9 cyl engine using these heads would measure roughly 7-8" in diameter. EVERYTHING from the skirt upwards is very nice.
Note the ringed piston. Good quality. The only part I would replace would be the rod, which has no bronze bearing and seems a bit cheaper than the remainder of the engine. The exhaust port is threaded; the intake port may require work as it is NOT threaded.
Balsaman, you were right, the covers are chromed aluminum. I'd replace these too with some CNC's covers with plain aluminum finish, and perhaps some more elaborate exterior styling.
