Rusty_OToole Posted January 17, 2020 Share Posted January 17, 2020 (edited) In case you wonder why they built such a monstrosity. Chrysler got a contract to build tanks during WW2. Ford was supposed to supply them with engines. Chrysler got the tanks into production several months ahead of schedule while Ford was 6 months late with the engines. Rather than delay, or turn out tanks with no engines, Chrysler engineers quickly whipped up a 30 cylinder engine by putting together 5 of their flathead six cylinder industrial or truck engines. They proved very reliable as they would continue to run even if one engine was out of commission but most were used for training. I think more than 1000 were built with this stop gap engine.

Guest Posted January 17, 2020 Share Posted January 17, 2020 I would have thought that every WPC fan would have known about this engine and it's history. I have even created a jigsaw puzzle at https://www.jigsawplanet.com/?rc=upuzzles Here are some other pictures. Link to comment Share on other sites More sharing options...

auburnseeker Posted January 17, 2020 Share Posted January 17, 2020 It would be more fun in a tank. Or is it only me that always thought owning your own tank would be pretty cool. I pass one on the side of the road by a VFW in some little backwoods town. I keep looking and hoping to see a for sale sign. There is a troop transporter next to it.

alsancle Posted January 18, 2020 Share Posted January 18, 2020 You don’t want a tank. It makes car collecting look smart. 2 Link to comment Share on other sites More sharing options...
nickelroadster Posted January 18, 2020 Share Posted January 18, 2020 Wasn't the Ford engine that was late a large overhead cam v-8? I think it was a real impressive looking engine that never panned ou. Link to comment Share on other sites More sharing options...

The Ford GGA is said to be the biggest production V-8 ever built at 1100cid, with DOHC 48 valves and 500HP @ 2600rpm. https://www.warhistoryonline.com/instant-articles/v8-ford-gaa.html Paul Link to comment Share on other sites More sharing options...
Roger Frazee Posted January 18, 2020 Share Posted January 18, 2020 How did they keep oil out of the cylinders in the bottom (upside down) engine? Link to comment Share on other sites More sharing options...

Usually not enough got down there to hurt anything but occasionally you got a hydraulic lock. Then you had to take out the spark plugs and drain off the excess. I imagine inverted inline aircraft engines have the same problem and get around it by using a dry sump oiling system. 1 Link to comment Share on other sites More sharing options...

The two lowest banks were still angled slightly up from the horizontal (7.5 degrees), and not downward like the lower cylinders of aircraft radial engines. So oil drained down the cylinders away from the pistons not toward them. You can see the slight up angle of the two lower banks in the lower picture Tinindian posted of the light green engine.
