Monster V-8 Showdown: 2020 Chevrolet Silverado HD Vs. 2019 Ram HD

2019 Ram 2500/3500 Hemi V-8 Engine

Buyers interested in the heavy-duty truck market — meaning three-quarter-ton and one-ton pickup trucks — are enjoying what could be called the Golden Age. All three of the big-truck manufacturers are offering all-new HDs for the 2019 or 2020 model years. Since pickups in this class are about heavy hauling and towing, that means their big motors are getting updates as well.

Both Ford and GM have all-new or replacement gasoline V-8s for their HD truck lineup; as we write this, we're collecting more information on Ford's new 7.3-liter gasoline V-8. We'll have more on that one later. In the meantime, here's a quick comparison of similarly sized gas engines in two HD competitors: the 6.6-liter V-8 that powers the 2020 Chevrolet Silverado 2500/3500 (and 2020 GMC Sierra 2500/3500), and the 6.4-liter Hemi V-8 found in the 2019 Ram 2500/3500.

Ram's 6.4-Liter Hemi V-8

The 2019 Ram 2500/3500 lineup will offer just one gas engine option and two power levels for the 6.7-liter Cummins inline-six-cylinder. The 6.4-liter Hemi V-8 carries over from 2018, but it's paired to an all-new eight-speed automatic transmission (the TorqueFlite 8HP75), which will significantly change the gas engine's performance. The 6.4-liter engine uses a cast-iron block with aluminum heads, while pushrod-operated overhead valves (two per cylinder) help it breathe. The heads include a partial hemispherical-shaped combustion chamber and dual spark plugs with a 10.0:1 compression ratio to provide a better, more complete fuel burn, achieving 410 horsepower at 5,600 rpm and 429 pounds-feet of torque at 4,000 rpm. The 6.4-liter Hemi offers fuel-saving technology with a wider range of cylinder-deactivation phases that allows it to run longer in V-4 mode when demand is low; additionally, there is a deceleration fuel shut-off feature when slowing down or coming to a stop.

GM's Direct-Injection 6.6-Liter V-8

2020 Chevrolet Silverado 2500/3500 6.6-Liter V-8 Engine

The all-new fifth-generation direct-injection gas V-8 will replace the stout but aging (20 years old) 6.0-liter V-8 in the 2020 GM heavy-duty trucks. The new, larger engine will be available in the Chevrolet Silverado 2500 and 3500 pickups as well as GMC Sierra 2500 and 3500 models as the gas alternative to the carryover turbo-diesel 6.6-liter Duramax V-8. The all-new engine will be mated to a modified version of the carryover 6L90 six-speed automatic transmission. The new engine uses a cast-iron block, aluminum heads, and forged connecting rods and crank. The 6.6-liter uses an overhead valve and pushrod system with two valves per cylinder to get as much power as possible at the lowest rpm possible. What's unique about this engine is that it's the only gas direct-injection engine (running a 10.8:1 compression ratio) in the HD class. It was chosen to deliver a more precise and efficient fuel shot into the combustion chamber at relatively high pounds-per-square-inch. GM told us the factory ratings are 401 hp at 5,200 rpm and a whopping 464 pounds-feet of torque at 4,000 rpm. GM decided not to offer any fuel-saving technologies on the engine beyond what's provided through the upgraded parts and material coatings. GM is introducing an all-new active oil pump that allows access to various amounts of oil reserves inside the aluminum oil pan, meaning it can bring the engine up to operating temperatures faster as well as cool more oil down during extreme work situations.

The Winner?

Since we haven't driven the new GM V-8 yet and information about how the Ram 6.4-liter Hemi V-8 performs is embargoed until Feb. 28 — we'll share our driving impressions then — choosing a winner becomes theoretical. It will be interesting to see how these two engines stack up in direct competition since the Ram Hemi has more horsepower (410 versus 401), but the new GM small-block gas engine offers substantially more torque (464 versus 429 pounds-feet).

Kudos to GM for more Torque and DI. Shame they don't have the 10spd behind it.

The Fiat HD is gonna MURDER the new Chevy HD on exterior styling and EVERYTHING about the interior.

Will 35lbs of torque make up being short 2 speeds on the tranny, ugly as sin, and an interior described by C&D as "a 70K kick in the balls"?

Time will tell and looking forward to the test.

The HD segment is all about working hard. Performance, handling and brakes are of the utmost importance. The GM wins as in all previous comparisons.

The 7.3 Ford will crush all comers in all respects. I'm saving a good cigar for that show.

Yes, I did just say that.

So the Ram has V4 mode?
and a turn dial shifter,
it doesn't sound like the Monster

"and a whopping 464 pounds-feet of torque at 4,000 rpm."

I guess PUTC forgot the Dodge iron 8.0L V10 from 25 years ago in the all-new 1994 Ram, producing 450 lb-ft at a far more useful 2400 rpm back then. Fourteen lb-ft can be written off as a build variance between one engine to the next on the same assembly line.

Hah...Ford is just waiting for the right moment to announce figures for their new Godzilla 7.3 which will certainly mop the floor with the competitors.....

@redbloodedxy

That should be quite a show. I'll pass, but thanks anyway

GM will destroy the dodge, I mean ram. The 6.4 is unchanged and isn't impressive bc of the weight the ram has compared to GM

The real test will be the new 7.3L. That will be tough, I really like what Ford brought to table with pushrod motor. Simple, durable and beastly......after years of embarrassment by GM pushrods, they jumped on the wagon.

GM already has an 8 liter in works that will decimate all anyways of the 6.6L doesn't get it done

Yeah no. The Government told GM no more big blocks when it administered CPR in '09.

I'm not sure the 7.3 is going to be the monster everyone thinks it will be. I' sure it will be rated higher than the 6.6 simply because that's the dumb game Ford plays. Let everyone release their specs and then beat them by that much. I'd be shocked if we see over 500 ft/lbs or over 420 hp. I also find it funny the number of idiots on the inter-webs that want to see this as an option for the Mustang.

No Fords in this story.

FMLionel?

Can Frank ever offer anything to this Forum...EVER!

BTW..The ancient 6.0L already beat the 6.4l up the IKE gauntlet

What do you think the 6.6L will do to it?

Also, to all the Ford guys, who are bragging about their hush, hush 7.3L

If the 6.6L puts a whooping on it like the Duramax does to the Super Duty. What will your excuses be then, since you're already talking all this trash? I'm very curious

Frank, you can open your tr@p first. I'm sure it will be very informative

Posted by: Frank

Yep, I'm sensing an anti-Ford sentiment from Papa. I wonder if it's rooted in jealousy?

Ford has done something great here by getting a whole new game of bigger gas engine competition going.

I wouldn't count on Ford crushing anything no matter how big the engine is. Ford has a reputation for big numbers but doesn't translate to the pavement...They were hoping GM would announce numbers first so they can adjust and fine tune before they brag

@ john

Totally agree with you.

Just like the diesel. All talk no walk

Ford and all their losers will be just as disappointed with the 7.3 as they are now nothing it being the a push rod engine LMBO! The Fords are eating so much crow!

The 8 speed wakes up the Hemi. Look at the performance difference between 2012 ram 1500 with the 65RFE vs the 2013 Ram 1500s with the 8hp70.

I suspect the 8 speed will do the same with the Ram 2500 6.4. The FCA legacy RFE are not great at putting the power to the ground. Something that GM's 6 speed is great at doing.

My guess is that 6.6 will out perform the 6.4, but it won't be by very much. The 6.4 will bet better mileage.

Sure amazing how GM keeps selling more trucks than any one else. Happy HD owner 8th one almost 0 problems. Always better trade in value than my friends ram that rattles and squeaks after 50k miles.

Ford sells more trucks than GM

https://focus2move.com/world-best-selling-pick-up/

The new FORD 7.3 will have a advertised @ max 453 H.P and 506 FT/LBS. Unfortunately for Ford fans, independent dyno testing will reveal a much greater drop in actual #'s compared to competing engines from more reputable manufactures such as GM and RAM. The new 6.6 GM engine employing direct fuel injection will produce better overall economy and performance with its broader torque curve.

The GM 6.6 will have a broader, flatter torque curve.

Obviously those EcoThirst engines from Frod are not so good for work. Why? FE would be poor. So, would you buy an EcoThirst 1/2 ton for work.

That's why there is no 5 litre EcoThirst. Imagine how dreadful the FE would be in an HD?

I still wonder why they use a big bore forgot diesel four in the bottom end work trucks. They would be priced similar to the big gas V8s have better torque and be far more efficient.

Real trucks have diesel engines, how many farmers have gas tractors?

When people really evaluate what they need to get the job done they'll discover that big gas engines will do fine as long as gas stays in its current price range.

If gas remains cheap the Cummins motors will remain popular with the HD crowd and the Duramax and Powerstrokes will be hard to sell.

It's about reputation and the Cummins is like Mom and Apple Pie. I talked to a guy after church tonight and he was telling me about his 1995 Suburban 454. Trouble free after all these years. Still has the same trans. The key he said is don't abuse 'em. Hard not to agree with that.

Its really good information, i like your blog post. Thanks for sharing

I love all the posts, I really enjoyed, I would like more information about this, because it is very nice., Thanks for sharing.

GM will sell so few trucks with the 6.6 gas that the average person will never drive one. You have to remember GM has less than 20% of this market.

prediction:

GM will introduce a limited production 2500 Suburban with the 6.6 gas engine, followed later by a 1500 Suburban with a differently tuned 6.6 gasser. Ford will cancel its plans for a HD version of the Expedition when that news comes out.

@ the dumb one

posting lies again

maybe this is just another misfire

your post is soooooo false

who do you think falls for your lies

People looking for a new HD truck would be remiss not to search out the most capable, fuel efficient and best handling HD truck. That search will result with a purchase of a new GM 6.6 HD if a gas engine it their choice of powerplant.

@papa

Good point on the special edition Suburban 2500, I would not be surprised if that happened. GM is always looking to up their market share of full-sized SUV's, which is currently at 67%.

The ZF 8-speed is a game changer.
The GM 6-speed was designed for the LS power band which peaks torque around 4K. GM expects them to spin between 4-5k on long grades.
The Mopar Hemi power band varies much more with displacement as the head design isn’t as radically different across the displacement varieties.
The big bore LS motors have large port heads that outflow nearly every muscle car era performance head. Which is why the 6.6, which shares the bore with the 6.2, can produce good torque numbers and power past 5,000 rpm.
In either case it is win-win.

As to the Ford 7.3, we don’t know all the specs, especially the nitty gritty details, but to write this off from passenger car use is foolish. First of all, those heads that support a 7.3, will flow really well on a smaller displacement engine with a CGI or aluminum block. That’s why it matters to cars and SUVs. Secondly, it is smaller than OHC Motors. Everyone is back to big bores again, something that makes OHC V8s gigantic. Since the efficiency of an air pump decreases based on the increases bore swept area, over square engines have a performance advantage, where as under square engines are superior for steady-state efficiency. But I digress...

Hey Oxi, that Toyota V8, garbage.

@papajim

Hard to argue with a TBI 454 and a 4L80e. The tie rods in the K2500 (IFS) Suburbans couldn’t hang, but man the old-school K20/V2500 Suburbans were great! I swapped a TBI bigblock into mine with the 4L80 from a 91, it was just awesome. Stainless headers, dual cats, 4.10s, I used to spank my Uncles ‘99 V10 SuperPoopy.
