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).

now you took my advise and posted under another user name

either way, you have nooooooo credibility

tntgmc got caught lying today

he did not add anything today

I let it all play out and tntgmc twisted his own neck

sooooooo funny reading that stuff

if it wasn’t for me, only your other user names would

reply to you, uh oh, seems like u misfired again

u have just been played. LOL @ U

This is papadim the insulter using an alias. He is on a marijuana kick tonight.

Ford could have committed to a 3/4 ton Expedition back fifteen years ago but they were fighting to keep the Excursion on the catalog. Terrible move. A 2500 version of the Expedition would have been less expensive to build and would only require some beefy drivetrain specs and a rugged front clip. The rest is standard stuff from the parts catalog.

Instead they stuck with the Excursion and it was too expensive to build and was WAY too heavy for the 5.4 engine, used too much gas with the V10 engine. Should I say how much grief they had with the diesels?

As far as the 7.3 gas engine in the coupes/sedans/expeditions I just don't see it. Current Ford management is too fascinated with Green ideas for that.

and papajim posts right after Just The Truth calls him out

Tsssssssssssssssss

papadim the insulter is drunk again tonight.

JTT and the yard sale moron are accusing another commenter of using multiple IDs. What else is new?

@ papadim the insulter I have no control over what names you post under. Try staying sober and maybe you can remember what name you are using.

@ papadim the insulter Go to bed and sober up. maybe tomorrow will be a better day for you.

Yard sale----Do you know why in 1975 withdrew our troops from Vietnam? Because the failure of Vietnamization to win popular support, caused an ongoing erosion of confidence in the various American, but illegal Saigon regimes. At least, that is the popular version of what went on there.

We all know that GM makes better engines than Ford.

But you have to give Ford credit this time for at least on paper trying to make a long lasting engine with port injection and push rods and a large displacement.

That said, it is a Ford, so I wouldn't touch it with a ten-foot pole.

But this is a step in the right direction.

Yard sale---Did you know that the Astronomer Jan Oort discovered that the smeared out density of matter could be no greater than the solar mass per cubic parsec?

Buick,Olds and Pontiac were making over 500 ft # of torque at lower Rpm's in 1970,with carbs,and flat tappet cams,im not impressed.

@Rob

Take care not to put too much confidence in torque ratings from fifty years ago.

GM is also coming out with a new big block . Hopefully a reworked 8.1 L 496 .


Ok, so MSRP, so for $15K, they are dead even at 30 mph.
It's .3 secs faster to 60 and almost dead even at 1/4 mile
Again, WOW, For $15k, I can add a supercharger on it, to put the 6.2l performance in a whole different league. Do you see the logic here.
Also, so many Ford guys bashed GM for only offering 6.2L in higher trims, yet, it's ok for Ford to offer a H.O. in the most expensive truck on the market for a half ton??
I was going off of what I paid for my truck $44k to $75K what the truck was listed for, bc Ford is not known to lower their top tier trucks like a SLT or LTZ GM truck gets its discounts.
So the difference in price will be well above $20k+ if not closer to the $30k I mentioned

LIAR LIAR LIAR

@ Yard sale

Man you have serious issues.

This is about the V8's

Stay on topic.

You need to see a shrink man.

You are so caught up in yourself, you don't even realize what comment section your on

FOCUS, Calm down, Change.

Throw anything you want to at it, GM will win this one!! Engines are about the only thing they get right!

@Yard sale----liar, liar, pants on fire, hanging from a telephone wire.

Wait so you are saying that this is the 5th version of a direct injected gas V8 being used in a GM HD truck??

Because if you are not, then what are you referring to when you say generation??

What generation of the list of V8's used is the Ram would the 6.4L Hemi be?

TOO BAD FORD WAS CAUGHT FALSIFYING THEIR TRUCK FUEL ECONOMY RATINGS, I can't wait to see the results of the investigation!!

No wonder why people have been averaging 4-5 mpg less with their ego-boost engines than what the sticker says! I can smell a massive class-action lawsuit for this one!

At Ford, quality is job one!!

@fullsize: The current V8 GM direct injection engines are the 5th generation of the small block. This new 6.6 is the newest addition to the 5th gen family.... try and keep up,..... Geez!

Once again, GMSRGREAT provides chuckles to those of us who understand the heavy duty truck market. He "forgot" to mention one of the most important attributes... reliability. Ability to stay out of the shop except for routine maintenance. The GM trucks are notorious for breaking down far too frequently. That's why they do so poorly in the commercial world. Their sales have to rely on individual blind loyalty. Sad.

@gms

So because its called a "small block" and its a V8 he is calling it the 5th gen?? This gm v8 shares nothing with a gm v8 found in trucks before 1999. Two names since 1999 maybe.....

The Hemi V8 in the Ram is what generation then? Being how there have been several "Hemi V8's" before this one??

The 5th gen is an all new small block, differentiated by its use of direct injection. Try and keep up.

We have fleets of GM and Ford Full size trucks. I spoke with our technicians about which trucks are causing the most problems. Our techs are recommending to out fleet manager to ignore the cheaper to purchase Ford's and purchase the more reliable GM trucks.

Its funny how you deflect when you have no answer!! LMFAO!!

Yeah i would call it an all-new engine, one that has no relation to the "small block" from 1955 besides the company that makes it. Kind of like the Ford V8 of today has nothing in relation to the Ford V8's of 1932 besides both being made by Ford.

Where I work (Utility) total owning costs are tracked all the way down to windshield wiper refills. In the early part of this decade the fleet was a mix of GM and Ford. For the past 4 years it has changed to all Ford. The main reason is 5.3 AFM failures and Duramax head gasket failures between 150,000 and 200,000 miles.

I will add GM is not the same company as the old company ceased with bankruptcy. The GM that exists now was formed and bought the old GM out of bankruptcy. So no even the same company did not build both engines.

I work for a large company, and we found that GM trucks cost 61% less to maintain than Ford trucks. We have been switching to GM trucks over the last 3 years.

Flea market = papajim = tntOnline = liar

@ Full of $h!t

I'm not anyone, but TNTGMC

You have ruined this site with your multiple posts, so your the biggest hypocrite of ALL!

If anyone is a liar it is you.

Everyone knows how pathetic you are

Go buy a truck and offer something to the forum.

BTW..only you can change!

Have a great day

@ tntOnline Did you know that the psychiatric profession has the highest rate of suicide of all professions. Now let that sink in.

@ Full of $h!t

Did you know that being raised by 2 loving parents who teach you moral values, hard work, dedication, perseverance, and respect leads to great success.

Let that sink in a bit, and you'll see why you're where you are at.

Again, have a great day, and you only you can make yourself want to change.

1. Please explain the deflection.
2. Yes, I call the engine in my 2015 Silverado a 5th gen small block because GM designates it as a 5th gen. Why are yo so confuse. GM has offered v8 engines in their Cadillac line-up (North Star engine) among others that were not considered small blocks.

@tntonline You hate on anyone who dares say anything good about Ford. That says who and what you are. Hating on people who disagree with you is a sign of mental problems.

Start backing up your posts with factual data, stop spewing nonsense, or at-least back it up when asked t do so, and use only your name.

Then maybe you'll see change, people will respect your opinion, and then you can have civil--debatable conversations

Again, have a great day, and you only you can make yourself want to change. (say again 10 times!!!)

1. I asked you what gen should Mark have called the Hemi?

2. Not confused at all, just have to laugh every time the current Gm V8 in pickups (does it still go by ecotec? or maybe brought back vortec, well whatever the name wizards at gm say) gets referenced as if being a version of the traditional "small block" used from till 1998/99 in trucks. That engine did have several generations before being replaced by an entirely new design engine which now shares nothing.

Wait, are you saying the latest gen small block isn't a descendant of the original.

Let's compare:
8 pistons, 8 connecting rods, 1 crankshaft, check.
16 lifters, 16 push rods, 16 valves, check.
I see the resemblance, don't you?

an entirely new design engine which now shares nothing.

Please educate yourself about this before you run your motor. When you say "nothing" you open a door big enough to drive a aircraft carrier through

Where did everybody go?

The main reason is 5.3 AFM failures and Duramax head gasket failures between 150,000 and 200,000 miles.

Posted by: Just the truth | Feb 22, 2019 12:25:34 PM

I have heard about some AFM issues, mainly high oil consumption. Not sure about Duramax head gasket failures, I do know Duramax has longer duration warranty. However, you appear to be ignoring the imminent cam phaser and timing chain failures on the Ford fleet. Not to mention, cylinder head replacement due to carbon build up and frequent turbo failures, all of which occur long before 100,000 miles. Maybe you guys are running a fleet of unicorn Fords.
