Here are the last of the engine pics. One is common, the other not so. Any guesses? Ben

When I see radial I think Continental but there were other brands too.

The bottom one is obviously a 9 cyl radial aircraft engine, probably a Wright cyclone.

The top one looks to be a GMC inline 6, probably a 302.

Yep. Could be a Continental air cooled radial tank engine.

R1820 Pratt and Whitney?

270 OR 292 GMC military application Not the 6X in the pic. Also believe it to be a Tank radial. Could be from a LST. Jim

I'm with Nicholson on the top one. Has a newer style fan but still has a generator. From what I can see of the intake and overall height of motor I'm going with GM 292.

Bottom one I'm going to say radial from a tank, the accessories don't look right for an aircraft. Not sure on make.

They put the 270 in a lot of military stuff. It doesn't look like the 270 in my GMC but it would have more gizmos for the military. The bare bones look right.

Right on with the GMC 270 six cylinder. According to the museum,s info, there were over half of a million GMC trucks of the 2 and one half ton model built with this engine during the war years, second only to the jeep in numbers produced. The other engine is a 9 cylinder radial use in tanks, but has no carburetor...any further guesses? Ben

I own a 270 in a 51 3/4 ton GMC No finer engine in that class has ever been built recognition was pretty easy. My cousin owned a LST. Jim

That bottom one looks like the Curtiss/Wright radial out of a B-17 from the air museum at Dulles airport complex. Might be the Pratt & Whitney also, but it looks more like the Curtiss/Wright to me. Neat at any rate.

Never knew there was such a thing as a radial diesel engine.....neat! Ben

Goose · Apr 2, 2016

I saw on TV once where the Germans had diesel bombers in WWII, but I don't know if they were radial or inline.

SOME FAMOUS WOMAN AEROPLANE DRIVER SET ALTITUDE RECORDS BEHIND THIS ENGINE...BREATHED BETTER THAN GAS ENG...BE BLESSED, GRATEFUL, PREPARED...

Dean · Apr 2, 2016

They were two stroke, opposed inline.

Similar to, but much smaller and lighter than the Fairbanks Morse engines used in US submarines and (for a short while) railroad locomotives.

Serviceability was a MAJOR issue with such designs.

I saw one of those Guiberson radial diesels mounted on a test stand at the Portland, IN show some years ago. The guy started and ran it, quite racket. Didn't know it was from a tank.

Interesting article on the radial diesel. Turns out it was made in Buda's factory in Harvey, Illinois. This plant was eventually acquired by Allis Chalmers.
