I didn't know you could just reverse some components and change the rotation of the engine. I would have thought certain parts would have to be replaced.
The 671 often called "gray marine" engines were used on most if not all of the US landing craft commonly called "higgins boats", used to land troops on beaches in WW2, then tons of them were sold as surplus after the war and found their way into civilian watercraft.

If you are not careful when driving a truck with one of these engines, you can actually get the motor running backwards. Of course, then the blower is sucking instead and you have almost no power, but because it is only a two stroke, it can rotate backwards.
6v71 were also used by the military in M113 armored personnel carriers. I've done many rack adjustments and blower barbell replacements on them
Uses two of them doesn't it?
While I want to say "most" M4 Sherman tanks were powered by radial (gas) continental aircraft type engines, I know some were powered by 671 engines, two or three of them coupled together. Believe they were mostly used by the Marine Corps in the Pacific theater, while the regular army mostly used gas powered Sherman's in Europe.
Oh okay cool.
Turns out I was thinking about the M59 which was the predecessor to the M113, it had two engines but they were gas. I almost bought one of them one time like 10 years ago. Till I came to my senses and realized it would be completely useless and cost a fortune to fix haha.
One of our farm trucks, an early 80's gmc brigadier has an 6-v92T. It's a normal 6v but it has a turbo that blows into blower. Dad said when he rebuilt them back when they were newish the turbo would make more boost than the blower would consume and the back of the gear drive would be worn so essentially the turbo was putting power into the crank via the blower.
The only thing I know for land moving equipment to get the 16v92 is the BigBud 747 which is still the largest ag tractor dating back in the late 70's. From the factory it was 750ish hp and it's up to 1100 now but it sits in museums
The euclid dozer is the coolest detroit engined thing in my opinion. Back when GM did everything they put 2 6-71's, one in both sides each running one track. They pivoted in the center. Really cool castings and everything.
Close #2 for favorite detroit powered thing is a late 50's oliver 990. 3-71 engine.

And for total crazy, read into R G LeTourneau
He put 8, yes eight, 16v-71's onto a scraper back in the mid 60's.

Look at this thing!
