The Ford GAA engine was a 60 degree all aluminum V8. Those two facts are due to the original engine the GAC being a V12 aircraft engine that Ford designed as an alternative to the Allison V-1710 or Packard V-1650 but that the War Department never asked for nor adopted.

That intake manifold is a dual plane intake. The intake runners just look more prominent due to the fact that this engine uses stand alone manifold with a separate valley cover, where most V engines incorporate the valley cover into the intake manifold. You can see where each plane of the manifold feeds the two inner cylinders on one bank, and the two outer cylinders on the other. On a cross ram manifold each plane usually feeds one entire bank on one side, while the other plane crosses over to feed the other. I love your videos, and have binge watched almost all of them by now. LOL! Please keep 'em coming!

My father was in the national guard sometime between 1956 & 1963. He always loved telling me about the LeRoi 944 V8, I'm guessing he was off on the size. He said it was in a vehicle known as a "tank retriever". I don't know what kind of gearing and transmissions these things had, but they could retrieve a tank supposedly, hence the name(what do I know, Ive never seen one). His favorite part of the story, was telling people it got 2 gallons to the mile. They would reply "you mean 2 miles to the gallon". Dad would say "nope, 2 gallons to the mile"😂 My gosh I keep learning by subscribing to Adam's channel. LeRoi had been part of Westinghouse air brake, and thats where the name "Wabco" comes from (?)

One unique feature of the M123 was the differential braking lever that allowed the driver to brake the rear wheels on either side individually like a farm tractor in order to make tighter turns. And you really needed that in soft going because the rear tires outnumbered the front tires four to one. I don't know if differential braking was truly unique to the M123 but it was the only truck I've ever driven that had that feature.

-I was just about to mention that looking at a spark plug diagram at a K Mart in the 1980's I saw that there was a listing for a 534 cubic inch engine....But then you covered it. Great video! You probably know this already, but light aircraft routinely run 550 cubic inch and 580 cubic inch air cooled SIX CYLINDER engines; This is done so that they can make 300+ hp at only 2700 rpm, the maximum speed for propellers [Direct drive is standard, for reliability and weight issues]. If they go beyond 2700 rpm, they run the risk of exceeding the speed of sound and producing only noise and drag. The pistons of these engines look like coffee cans~

And boats DID NOT HAVE any of that emission controls. Plus topping it ofg was a Holley 4 bbl. That motor was so strong, I was talking to a guy at the marina was cruising a jet boat I asked him if he would run with me so I could see just how fast she would go, we did, hr said it got up to 47 mph. Plus it would yank and I mean yank 4 skiers out of the water without any hint of hesitation. Bad ass motor. My dad and my uncle owned a 1953 Chris Craft Continental with s Chrysler 440 with 3 2 bbl's supplying the air and fuel.thst boat had a tach and speedometer. Heavy heavy boat But9 she'd cruise all day at 34 mph, no problem and would touch 40 mph when he pushed her. When he did, you could literally watch the gas guage drop as we cruised along.

@alexinnewwest1860 To be fair, the early 6.9 diesel had head gasket issues too, that were later resolved with bigger bolts when displacement was increased to 7.3. Of course the 6.9 was still a MUCH better engine than any of the Olds diesels, and also Chevrolet's 6.2/6.5. The Olds diesel program would've gone better if the spent some more time on R&D, and hadn't introduced their engines prematurely. They weren't ready yet! Bigger/better head bolts/studs, and a good fuel/water separation system would've made the Olds diesel story much brighter 🌞 in my opinion.......

-I suspect that they produced this as a "Hot V" V8 like a modern Audi, for the reason that it was designed with Fairbanks, Alaska in mind. During the winter in Fairbanks, it is not unusual for the temps to go down below -20 F, and that is why you see the rolled up fabric covers over the radiator air intakes. An engine with this low output is not going to put enough heat into the Hot V to make fuel vaporization an issue, so hot starts wouldn't be a problem and the wires were away from the heat as a result, a win-win.

That's called a "hot vee" design. It has many benefits over outboard-mounted exhaust manifolds, even though it does heat up the intake charge. It's not necessarily conducive to high performance, but it does greatly improve efficiency. All the heat rises away from the engine in a more concentrated area, keeping the cylinder heads much cooler, etc. I believe Mercedes actually has a modern twin turbo V8 super car that has this design.

Our city fire department had a Ford cab-over fire truck, that had a 612 ci. engine in it. That was in the late 70's. I done a tune-up on it. (Points & plugs) for those of us that remember what points are. 😅

The 884 seems like a good choice for a monster truck. Exhaust going straight up through the hood and torque for days. If I had the money, I would definitely like to find out

i love any motor that makes huge torque at low revs..

I'd guess that the inboard exhaust ports/manifolds could be an indication that they may have had their eyes on possibly turbocharging the engine at some point.

Hall Scott had a large v 12 gas. Le Roi is/was? Famous as an air compressor company as well. I had worked on several over the years. The large V12 gas is very similar to their V12 diesel that I used as a back up generator, when we needed more power, or were securing the steam plant. Have fun

the hall-scott v12 was called the defender and was used in some american and british navy boats during ww-II.

In french, Le Roi translates to 'The King' . Roi pronunciation roughly sounding like 'ruah'
I imagine the exhaust inside the VEE was probably both for packaging and to heat the intake manifold for improved cold start performance since they were often used in generators and such.

300 horsepower at 3000rpm but that’s because it’s a generator designed to run at full throttle all the time and needs to be reliable

The reason for the intake and exhaust on the same side of the head is most likely a cost savings measure, using the 4 cylinder head castings for the v8. Detroit Diesel did the same thing on thier V block engines

Le Roi and Wakesha(sp?) were popular as drilling rig engines many years ago.

We had a Le Roi engine on a fox forage harvester.

Sorry if I missed it, but did any of you catch what was the overall assembled engine weight? Thanks. By comparison, the late 1950s Ford Super-Duty V-8 534 cubic inch was about 1,000 pounds. I think the GMC V-6 Hercules truck-only 305 cubic-inch ( smallest displacement of the family ) was around 800 pounds... These two examples were from specific truck engine design families - all cast Iron, heavy construction, modest horsepower but fantastic torque at low-rpm truck-only engines...that had NO business being in passenger cars or 1/2 ton pickups.

Do you know about the weights of any of the other engines in that series? The gmc v6s? I know some had larger cranks so maybe those were heavier but does the weight correlate with the displacement?

@machineman8388 Sorry I cannot locate a chart for the GMC V-6s....but I do know the Ford Super Duty were heavy... ( 401, 477, 534 Cid). That's one reason they should never be put in a passenger car or light-duty truck.
