GM Gen VI V-8 engine will be available in 2027

[OneLonelyBurrito]

Looks like GM filed for a patent on a new cylinder deactivation mechanism that might be used on the Gen VI engines. Source Based on the patent filing diagrams, looks to take inspiration from the rocker arm based cylinder deactivation that is used on some GM 3.6L V6 engines and on Ford's 5.0L and maybe 1.5L 3 cylinder engine. Looking through the diagrams it appears the collapsing mechanism is located at the rocker arm instead at the lifter. From the pictures, I like this mechanism better than the collapsible lifters. Definitely will be easier to replace then the current lifters if they fail. It seems like the collapsible rocker arms on the 3.6L are more reliable then the lifters on the V8s. So hopefully that carries over to this new mechanism if used.

Multi-Cylinder Deactivation. No thanks.

Disabling it is nice.

Has GM figured out how to build the 6.2 again?

I mean a new small block could be great, but they cant seem to build the current one.

It really doesn’t matter they don’t have know to build right people keep on buying them regardless . Smart move on them they give a band fix (0w40 ) get folks through there warranty. Then when the 27 model comes out with the new V8 folks will trade up to those . There’s a lot people loyal to GM they will continue to buy there products recalls etc maybe they’ll change there ways. But why should they ?

Got the band aid fix this week. They do warranty my 2024’s engine til 2034 or 150,000 miles so that’s nice.

Thats a pretty fair comp. Id feel ok with that.

I'd still avoid a known gamble if I could.

There are two prices to pay for a blown mill, the replacement of the mill, and the loss of the trip you are on when it happens.

A breakdown could kill a business trip, jeopardize 200K in towed product, miss a show I paid 10K to be at, wreck a once a year vacation and so on...

Yeah, I guess there’s an unknown to any vehicle and I feel pretty good about mine with 36,000 miles on it. I feel like a problem would’ve surfaced at this point but you never know.

We only use this locally and maybe one or two family trips a year (under 400 miles one way). It’d be a major inconvenience if it died on a trip but I’d manage and likely end up buying another one while I waited for GM to fix it. See, they know they’ve got me, I’m a sucker!

EPA smackdown. Was long overdue. Now GM needs a smart CEO. Barra has been a disaster. She was gonna make all cars electric by 2035 or something. She was all in! 20 billion dollar loss for that stupidity.

GM is a good example of a company lost to a one-way ideology that doesn't work. One person at the top runs around in her leather jackets acting cool like she's Fonzi. How does someone like that get to be CEO? All I can guess is all the people around her are stuck in the same group-think. If GM goes bust again, the government will just bail them out again... that must be it. Ford looks to have an intelligent leader, though I never heard him standing up for what's right before.

gen 3 ls motors are probably one of the most reliable V8’s on the planet. even gen IV motors without afm/dfm (6.0L LY6) are probably a little better. i service a fleet with a ton of these motors and own a LQ4. we have many LY6’s in the 250K+ mile territory with 11k+ engine hours and they start up and go to work daily. nothing beats the simplicity of working on an LS motor.

i also do LS/coyote swaps on the side. i can have an LS mounted up, wired up and running in a matter of hours. hard to argue with success. i don’t mess with afm/dfm motors in swaps, but i do work on them and have yet to see a failure in the fleet. good oil and filters haven’t let me down yet.

150,000 miles is good

I hate LS engines. Can't stand them. Would much rather have an old school SBC.

you must be nuts!

 

[ls1mike]

If the LS style engines are called "Small Block" then what is the big block, that is now used in cars and trucks?
They have zero resemblance to the real SBC. Its just nice that Chev performance still offers them and the real BBC as well.

There is no Big Block. They are all small blocks. Big block and small block is not determined by displacement. It really has to do with bore spacing and physical size. The ls and lt engines are small blocks by size. The 6.6 in my truck is a small block. Make no mistake, they are small blocks. The non dod 6.0 is the best small block GM has made.

GM 7.0

 

[ls1mike]

you must be nuts!

There are always a few.

To be honest, the 6.6 deserves a spot in the annals of muscle car history. In the mid 70's the Pontiac Trans Am could be had with a 6.6 (400 cu in.) decal prominently displayed on the backwards hood scoop. Back then hardly anyone knew what 6.6 liters was.

You know I am a GM guy but in stock form that was not even a good boat anchor.
