PIckuptrucks test Gas HD. 6.0 no I'm old tested

Dirtbiker · May 13, 2017

I would love to get my 2006 8.1 liter back. I loved that motor!

Hockeylover86 · May 13, 2017

Just wish they would have continued the 454 as an option and brought it up to date right along with the 6.0. I owned several 454's since the early 70's, my first a '73 El Camino SS, and always had a fondness for it. Would be interesting what the performance of that motor would be with the same technology that is in the L96.

They kind of did that with the 8100.

They could easily do a modern version of that, 450hp & 500lb/ft with a HD 10 speed trans would sell pretty well i think as a diesel alternative.

454 or 8L, it should sell pretty good as alternative, especially since all the emissions stuff on the deisels. It might have been a reality already if we hadn't dealt with that major high fuel cost ordeal a few years ago. That was a major setback for high cube muscle engine revival.

You seem to have your ear to the ground. Is there any sign of a small diesel for the pickups down the road? Our next project in '08 (before the plant closure announcement) was for a 'baby' Dmax.

Lots of talk, but I haven't seen anything specific as to a diesel for the 1500 or a smaller one for the 2500 for those that do not have the need for a full blown Dmax. I would have thought GM would take the 2.8L diesel they are putting in the Colorado/Canyon and maybe up displacement to 3.0, thereby bumping up the power, and dropping it in a 1500. Something like that would easily do what a 6.2L would do, as far as pulling. The 6.2 would obviously beat it off the line for the pickup racers out on the street. But hitting max torque at 2100 RPM with that diesel, and having as much or slightly more torque to boot, it would be a real worker. And since they already have most of the R&D out of the way with the 2.8L, it would be cost effective to implement. I am pretty confident that they would sell quite a few of them. If nothing else, but an owner having equivalent V8 power and better fuel economy that diesels typically deliver.

I bet GM already has something ready to go for the 1500's and they are just waiting. Ram has had their ECO diesel for a few years now and it is a target for emissions crap. Emissions aside the Eco-Diesel appears to have sold well.

Now Ford is pulling out a Mini powerstroke with the 10 speed. Depending on price/Mpg/power that should be a good engine choice.

GM has the 10 speed that will make it into their trucks hopefully for the 2019 model year. By then they will probably put a diesel out that can at least match the other two on the market.

That is indeed possible. GM stays pretty tight lipped about what they have in the hopper. They are likely to do something to keep up with the competition.

Initially, AutoGuide thought this truck might be testing the rumored new HD gasoline engine, but some of their readers pointed out that this truck appears to have a DEF tank and a venturi exhaust pipe. However, others pointed out that the DEF tank is small and in the wrong place. I think AutoGuide might have had it right in the first place, it may be a gasoline truck disguised to look like a diesel. And that DEF tank is as phony as the covered Ford emblem on the grille.....

They got all they could out of the 454 with emissions crap and all. They needed to go a different route and they did. But the 454 was a mighty fine engine for sure.

Not sure what 454 everyone is remembering, I remember a 454 that was notorius for eating cam lobes? Especially the later ones, this 6.0l would run circles around a comparable 454 truck? I know technology changes, the 454 was a dinosaur.

The 6.0l seems to be a decent platform, just needs more umph...a tad more displacement would be perfect. Sort of like they did with the early Dodge Cummins and this current 6.0l...detune it so it lasts, but still has the HP/TQ to do the job. Even if they offered a deeper gear ratio than 4.10, like the 4.88 offered by Ford...

My hunch is they will come out with a 6.0l to 7.0l offering to keep up with the numerically larger offerings by Dodge and Ford. And they are falling behind in the multi-speed transmission competion, so I anticipate something in that arena also...

Keeping my fingers crossed, I'll be in the market in three years...

Ford has already announced a 3.0 diesel for the F150 for 2018.

GM had the 4.5L dmax ready for the 1500's almost a decade ago then got hit with the double whammy of emissions regulation changes and the bankruptcy so it got shelved/scrapped.

I think the diesel cost penalty is too high to be a good choice in a half-ton where a gasser works just fine.

I am specifically remembering the 454 I had in my '98 2500. it was great. But I did mention that if they had used the same technology they implement in the L96 6.0, the 454 would be a killer engine.

KARNUT · May 14, 2017

I used several 454s back in the day. One stands out, I built it for a 74 impala along with a 700R4 with a 373 my wife drove for 3 years. Every so often I take it test and tune and run a 14.7 on street tires. Later I transplanted the driveline into a 76 nova it ran mid 13s on street tires. Traded the car to a friend who pull the engine put it in a low rider pickup. Never had reliability problems with 454s. The only problem I ever had was blowing noses off starters, the cure was a kill switch, I wheel it over and hit the switch.

That's the motor I was referencing. I didn't have any details, but after we had finished the hybrid retooling (how did that fare on the market?) we were to start the diesel.

GM Statement Regarding the Duramax 4.5L V-8 Diesel

2009-03-11

Given the current economic climate, GM has reviewed and updated its U.S. product portfolio and has decided to place on indefinite hold its previously announced plan to add a Duramax 4.5L V-8 diesel engine in 2010 to its Chevrolet Silverado and GMC Sierra light-duty trucks.Chevrolet and GMC will continue to offer a heavy-duty Duramax 6.6L V-8 diesel, which is class-leading in both horsepower and torque. Light-duty truck customers can also choose from several fuel-efficient gasoline engines with GM’s Active Fuel Management mated to a six-speed transmission or a new 2-Mode hybrid that provides up to 40 percent improved city fuel mileage and 25 percent improvement in overall fuel efficiency. In fact, no other fullsize pickup has better fuel economy.GM remains optimistic that the Duramax 4.5L V-8 diesel may be a viable option in its future portfolio.
