I dont think Teterboro museum has one. I live 10 minutes from there, ill have to check on that one. Its probably a scan of a picture they have of it. Paterson museum has a pratt 2800 on a real nice rotating display table.

Odd. Im on page three, right next to n5151ts' avatar. At least I'm with a fellow WIXer instead of some maroon haired skateboard kid.
And since I first posted on this thread, I've acquired Graham White's book, "Allied Aircraft Piston Engies of WWII."

So I would surmise that the ALLISON X-4520 was also a potential competitor for the 4360.

Looks like the X-4520 was delivered to the Army in 1928....

Pull up the LYCOMING R-7755, a 5000 H.P. mega motor that was the backup plan in case the 4360 didn't pan out in the B-36. It is the largest aircraft engine ever built (excluding dirigible power) the Smithsonian has one of the two ever built and standing on it's accessory end it looks like a circle of straight 6 truck engines

The picture posted above isn't the R-4090.I think that it's the Wright Tornado.That was even more of a monster of around 7750 cubic inches.I found a site with pictures and info on the R-4090,which was more or less an R-3350 on steroids.Here's a link to the site:

I tried to correct my post above,but I couldn't,so here's a correction.The earlier engine pictured was the Lycoming XR-7755.Here's a link to info on that engine:

This link is good for info and pictures of the R-4090.It looks a lot like a Wright R-3350 on steroids:
