Eleven hundred cubic inches, that’s how large an engine a tank crew needs to operate a Sherman safely and reliably. Initially, Ford had not considered building a V8, hence the design is like no other, but it quickly became one of the all-time favourite US army engines. During its time, the Ford GAA was the largest gasoline V8 ever made.

In the late '50s/early '60s we owned a cabin cruiser which was powered by the GAA's cousin, the GAN. It had roughly the same specs. It would easily plane our all-plywood, 36 ft. Jeffries cruiser at 30+ knots. I turned my first wrench on that engine, because my Dad couldn't fit in parts of the engine compartment! Later, when I was 12, I was able to pilot, navigating a crowded harbor to our mooring. Several times, I had to blip the throttle to avoid sailboats on a direct collision course (sailboats have the right-of-way). The boat would lurch forward like it was shot from a cannon! That engine took us to Catalina countless times, and all the way to San Quintin (Mexico, not prison) and back. On the Mexico trip, it developed a head gasket leak, but my father just pounded some copper wire strands into the gap, and we made it home. The engine finally was damaged by gulping some seawater back through the exhaust, a freak wave being the cause. A valve broke off its stem, and embedded itself into the piston! It still ran! Having a spare engine in our storage locker, we swapped it out, and had it running again in 2 weekends...that piston sat on my Dad's desk until his passing in 1990. Great memories of that boat, and, especially of that 1100 cu.in. BEAST under her engine cover...thanks for a great video.

@g.n.b.3351 Год назад

As the design was originally intended to be an aircraft V-12 the design specified a 60 degree bank angle. When the change was made for use as a V-8 tank engine the design was too far along to change the bank angle to the V-8 optimal 90 degrees. Therefore as a 60 degree V-8, a cross plane crank would have provided no benefit so a flat plane crankshaft was used.

@throttleblipsntwistedgrips1992 Год назад

not to mention you dont want split crank pins in a mill that big.

@jwalster9412 Год назад

I would have thought adding a flat plan crank would have been beneficial to a 60° engine.

@keithjurena9319 Год назад

Flat plane crank needed no special die to forge.

@g.n.b.3351 Год назад

Keep in mind that an in-line 6 and V-12's use/require a cross plane crankshaft for even firing AND primary balance. But there are 3 planes involved, crossing at equal angles of 120 degrees, not just the two planes of a V8 crankshaft which cross at 90 degrees. So when the decision was made to alter the design for use in a Sherman tank as a V8 rather than as a V12 aircraft engine, did the engineers think about giving it a cross plane crankshaft with just two planes crossing at 120 degrees? Or 60 degrees? Would that have made much of a difference in the basic balance dynamics of the engine? Hard to say but I suspect that in a tank there is so much going on that perfect balance was not a priority.

@Carstuff111 Год назад

I am not personally a Ford man, however, I do respect a lot of what Ford has managed to do over the years. They were great at bringing the dual overhead cam V8 to the masses. And engines like this beast prove that when Ford does something right, they can knock it out of the park.

This engine is 2/3 of a merlin v12. The plans sent from UK to US to make Merlins were intercepted by ford and they stole the design. They even kept the firing and 60 degree v angle. Ford went back to making flatheads for 20 years after the war.

The 427 SOHC. A friend’s dad has had 3 of these in his shop over the last 30 years, one of which I’ve seen. Beast of a motor. The building that kept all records of how many were built burned to the ground decades ago, leaving only a semi educated guess as to how many were made. Being an over the counter motor, they were never factory installed in any cars. No one knows how many are still in existence. In today’s market, you’re looking at a solid 50k for a turnkey motor, 15-20k just for workable non running engine. Back in the day, Ford advertised the engine with lower numbers than it actually made due to insurance/legal matters. In reality, a correctly built Cammer in factory form produced around 800 hp and 650-700 lb-ft of torque. It’s not unheard of for a NA motor to reach 1,100 hp when fully built. Truly a masterful work of engineering

Hi VisioRacer, excellent presentation! I hope that viewer understand how advanced our technology was back then. Germany could produce little (or big) marvels but not in great quantity. Germany built (some) good engines but so did the Allies, think about the Merlins, the Allisons, the GAA and the Curtis-Wright/Pratt & Witney series of radial engines, to name a few. Consider the complexity and fine edge of the technology used in valve train/drive and/or crankshaft balancing. Remember that these marvels were produced by the thousands and assembled by an uneducated (for the most part) man/woman power trained "on the premises". We (Westerners) did make those achievements and we could still do... if we wanted to and... worked for it. The complexity of a B-29 Bomber is insane! At its peak production hey days, Ford's Willow Run B-24 Liberator factory was delivering one ~36,000 lbs/16,500 kg 4-engine bomber every 55~60 minutes! Imagine the process of such undertaking, this back in the forties! Peace be with you, Ciao, L (Veteran)

@wruenvadam Год назад

Considering this engine's capabilities, one could only imagine the magic that would have been the V12 aircraft variant once it got superchargers or even turbochargers. On some level I think we were robbed of what could have been one of the greatest aircraft engines of WW2 and could have sat right alongside the Pratt & Whitney R2800, RR Merlin, and likely took the place of the Allison V-1710. I absolutely love the V-1710. Many people rag on it as not being good enough for the P-51 but that just ignores the success these engines really had throughout the war, most notably in the likes of the P-38, but was also in the P-40, P-39, and P-63. They were reliable engines that were also easier to maintain than the Merlin. However I 100% believe that if Ford had managed to get their foot in the door with their V-12, it would have been a serious contender for a powerplant for the P-51 assuming they already had supercharger plans in the works as well, which I wouldn't doubt that they did. But alas we can only dream.

@kingssuck06 Год назад

If you look at power levels the Allison was just as capable. The allisons in the P-38 that were turbo/supercharged made as much power as the merlin. The single stage supercharger is what made the allison seem so much weaker. It was also much easier to service and maintain

@wruenvadam Год назад

@@kingssuck06 I think it just took them a little too long to develop a proper supercharger for it. The most powerful turbocharged version I believe was in the P-38K with something over 1800hp, and then they got a supercharged version pushing something around 2000 in the F-82 I believe, but by that time Packard had gotten the Merlin's to have a good bit more than that. And little do people know, the P-51A with the Allison engine was still the faster than the B/C/D variants at low altitude. It was a damn great engine and I'm not saying otherwise, just held back from being as good as it could have been for a while because of difficulty getting it to have proper performance at very high altitude without a turbo.

@andyharman3022 11 месяцев назад

Ford had the GAC V12 designed first because they saw an opportunity to build an engine competitive to the Merlin, but at much lower cost and higher production rate. That effort was stymied when Packard licensed the Merlin design, revised it with American production standards, and started producing it in Muskegon, Michigan. The GAA/GAC even had the same bore and stroke as the Merlin: 5.4" x 6.0"

@billwilson-es5yn 3 месяца назад

The Allison had been in production since 1930 so had its bugs worked out with a known cost that the Army Air Corps expected to become lower once in mass production. Rolls-Royce was still producing the Merlin by hand-fitting the various parts like building a custom engine. The British aircraft mechanics preferred the Allison engine since it used 50% fewer parts with replacement parts being ready to install straight out of the box. The British Government asked Ford about manufacturing the Merlin due to RR being so slow. Ford declined the offer since he was trying to sell them his aero V12 so gave the Merlin blueprints to Packard to look over. Ford's V12 was turbocharged and used fuel injection so it took his engineers a couple years to figure out how to make the V8 version run on carburetors. They were still working out the bugs when it started being used in the M4 .

Ordnance used the twin GM Diesels in the M10 tank destroyer since their high torque at low RPMs could get one moving faster from a dead stop. Chrysler tried to get the British interested in using their A57 Multi bank engine in their Lend-Lease tanks. Their Army politely declined using those so Chrysler showed those to the Soviets. The Russians said those were too complicated and needed simple Diesel engines instead, so received the twin GM Diesels in their Lend-Lease tanks. The British got stuck using the A57 with Chrysler working with their tank mechanics to find ways to make servicing those easier. That was done by pulling out the giant engine by using a clever self adjusting hoist bar.

@aldenconsolver3428 Год назад

Maybe its just me, but I think that is the best-sounding engine I have ever heard. It sounds stronger than any petrol engine there is. The big aircraft piston engines put out more horsepower but they do it by buzzing and the GAA is like a bass drum compared to them.

@eclipsegst9419 Год назад

Yea the sound of a GAA is just so iconic. You hear one and you immediately think of a Sherman. Even just as someone who watched ww2 movies and played ww2 games growing up, i immediately got called back to them when i heard that sound.

During the 1930's the US Army was developing Christie concept combat cars that used the Liberty V12 engine. They wanted to make it lighter and shorter so made prototypes using a surplus Wright R975 radial aircraft engine. The drivers liked it due to having a smooth delivery of power and the mechanics liked it for not having a liquid cooling system plus being easy to remove and reset. The Ordnance Department decided to keep using the Wright radials in the M3'S and M4'S due to the commercial air carriers having plenty of surplus R975's plus parts on hand (they switched over to using more powerful Wright radial engines) plus Wright was still producing new engines. Ordnance had Continental take over production of Wright's smaller radials (a smaller one was used in the M5) while Chrysler figured out how to mass produce armored tracked vehicles. Ford had his V12 aero engine completed by then and was trying to get the US Army Air Corps and British Air Ministry interested in buying it. It was superior due to being fuel injected and turbocharged. The USAAC decided to keep using the Allison since it's bugs had been worked out over the past ten years, their mechanics were used to working on it plus the War Department knew how much each cost and expected that number to become lower once in mass production. The British Air Ministry declined Ford's V12 and asked him to manufacture the Merlin instead due to Rolls-Royce being too slow. Ford declined and handed the blueprints over to Packard to study while he converted the V12 into a V8 tank engine for the Ordnance Department. That took a few years as Ordnance tested them in their T Series being worked up to replace the M4. The V8 allowed Ordnance to design a hull with a lower height and a lighter weight fluid drive GM Hydromatic transmission. In the M4 it allowed more space for wet ammunition storage on the floor. The V8 also held up longer than the R975 when hot-rodded by the drivers. Both had speed governors that were tinkered with to increase the tanks speed with drivers using engine braking to slow down when racing along. The R975 was expected to run for 200 hours before being swapped out for inspection and refurbishing. Hot rodding had reduced that number to 120 and even 80 hours so the Army now started removing all radials after 150 hours of use. The V8 could sustain being hot rodded for more hours but still had some problems once subjected to rough battlefield operations. Components were still being redesigned when the war ended.

@TheSaturnV Год назад

The early choice for massive radial engines is partly to blame for the Sherman's high silhouette. The other being the M4 was based on the M3 Lee, a compromise design that tried to satisfy requirements for a larger caliber 75mm they had to stick in the hull and still have a gun in a turret

@TheSaturnV Год назад

That's actually an old myth about the M4 with the petrol vs diesel argument. The cause of fires in the early Shermans was due to ammunition storage. The combination of moving the ammo lower in the hull and placing it into wet stowage bins (filled with antifreeze) gave the M4 equal to and sometimes lower burn rates than any tanks it met on the battlefield.

The M10 Tank Destroyer had dual Detroit Diesels of like 200 or 250hp each I believe but my dad said it passed the Ford V8 going through the mud possible a broader power band where it was needed for lugging through the mud and bogging heavy work.

@buckhorncortez Год назад

The tank destroyer was a much lighter-weight vehicle than the Sherman Tank. The GM design had two parallel 16-cylinder motors. The GM motor had a 100-hour operational life while the Ford GAA had a 400-hour operational life.

@Oliver66FarmBoy Год назад

Don’t know where you got your information from but everything you stated is pretty much incorrect. The GM 6040 was NOT two 16 cylinders. It was two inline 6-71 Detroit’s side by side giving a total displacement of 852 cubic inches, 410 flywheel horsepower and 1000 ft/lbs of torque, driving through a common gearbox to a single output shaft. This is why it got the nickname twin six pack. They were one of the more reliable allied tank engines of the war it it was not uncommon for them to log 2000+ miles between overhauls. And most of that was contributed to wear and tear on the engine gearbox more than the engines themselves. It is common yo find Detroit’s from the 40s and 50s with 20000+ hours still running today that have never seen a major overhaul.

@@Oliver66FarmBoy At least he was right about the lighter weight of the M10. 🙃

@deadon4847 5 месяцев назад

The M10 and M10A1 were mechanically identical except for their power plants. The M10 used the General Motors 6046, a twin engine formed from two Detroit Diesel 6-71 inline engines mated to a single output. The tandem engine produced 375 horsepower (280 kW) at 2,100 rpm. One advantage of the GM 6046 was that the engines could be disconnected at will from the output and run independently. If one of the engines was damaged or destroyed, it could be disconnected and the other engine used to move the vehicle. The engine of the M10A1 was the Ford GAA, an 8-cylinder derivative of an ill-fated V-12 aircraft engine project. It produced 450 horsepower (340 kW) at 2,600 rpm. When tested side by side in September 1943, the M10A1 was judged to have superior automotive performance to the M10. Even though it produced only slightly less torque, the M10A1's engine was far lighter, and used a common fuel like the rest of the Army's vehicles (gasoline). By the time the test results were released in February 1944, the Army was committed to using the M10 overseas. As a result, the M10A1 was kept in the United States for training.

Ford engineers analysed hell out of the RR Merlin and the GM Allison and said: "We can do better than either." and so that is how the V-12 GAC was born.

An interesting drive system for the DOHC. Worm gears at the bottom of a long shaft, which has worm gears at the top to drive the cams. ingenious, and likely very reliable. Also, a 60-degree cylinder bank is very unusual for a V8, which are commonly 90 degrees.

The mistake was made to delete four cilinders on the Ford V12. Beter lengten the Sherman body (which they already did for the A57 Multibank engine). The British did better with the 1650ci RR Meteor (Simplyfied Merlin) and made in their turn the mistake not to make a diesel version of it! Shortly after WW2 Rolls Royce / Rover made also a V8 version for heavy tank transporters etc., the Meteorite, which was made in a Petrol and Diesel version.. So they where close to a liquid cooled V12 Diesel like the Sovjets already had for years!

@brandonfairbanks5764 Год назад

Cool engines but a couple of super simple design changes could have made these engines legendary. A 2 bolt not skirted block on a engine that has harmonic issues. That and a huge 2 barrel carbs on each end when dual 4 barrels would have provided much more even fuel distribution. Hell to this day the Windsor platform is plagued by 2 bolt mains and 4 bolts per cylinder heads. It's like Ford wanted to dangle that carrot right in front of our faces. I bleed blue until the day I die but dang man.

@servicioelectromecanicocue7025 Год назад

It's incredible thats Ford didnt use more this design for comercial trucks, with low displacement

@brianb-p6586 5 месяцев назад

It has 18 litres of displacement, which is about 2 litres larger than any on-road truck engine currently offered in North America or Europe. Cummins builds an 18 L (C18) for on-road-capable trucks, but it is not available for non-military on-highway use. Did you mean to suggest that they could have used it in a lower-displacement version for commercial trucks? There was no market for very large commercial gasoline engines, this design (with dual overhead camshafts) is too complex to be economical to build, and the 60-degree vee angle is undesirable for a V8 (although it is narrower than a proper 90-degree V8).

@bobkonradi1027 22 дня назад

Another problem with some of the other engines for the Sherman tank... the Chysler "multi bank" engine weighed over 4400 pounds, and the dual GMC 6-71 diesel also weighed over 4400 pounds. By contrast, the Ford GAA V8 engine only weighed 1440 pounds. That's a weight savings of 3000 pounds per each tank. Easier to ship, used way less fuel, could travel over softer ground than the heavier tank models.
