Is there any differences between lq4 and this 6.0? Only thing I really know with out popping the hood is vvt on the sticker. Don't know head #s or squat really.
This 6.0 is a Gen IV engine with rectangle port heads and (I think) VVT and DOD. It piuits out good power because of the better heads. It's a different animal than the old LQ4.
I've rode in one and didn't hear it shut down cylinders. Just a stripped down work truck model like the one I'm looking at. Thanks for the reply . Long term plan is big Whipple/ injectors/headers/ fun daily driver/parts hauler......
You usually won't "hear" cylinders shut down, as it's under such a light load or no load that it's nearly transparent in operation.
Agreed. I never hear or feel my Silverado going into DOD mode. If it weren’t for the display telling me when it’s doing it, I’d never know. It’s a seamless process that’s ultra smooth, and only at light load while cruising.
Biggest difference with the engine in the new truck your looking at is the direct injection. The gen5 is a completely ditterent engine, don’t get me wrong here, but the shortblocks are similiar. It’s the heads, intakes, injection system, and ECM that sets them apart from the previous generation engines.
I must admit however that I did not know GM was still building a 6liter. I thought that they killed it and went 6.2”s in its place. Good to know...

Reason: more info...
It's a gen 4 6.0 with truck versions of the LS3 heads, only difference is LS3 heads come with lightweight valves
There's a lot of LQ4's that had gen 3 rods and some had gen 4. The motor you're looking at has gen 4 stuff which is excellent. Gen 4 rods are much stouter, the gen 3 were by no means terrible but you are getting the best 6.0 to have.
Originally I figured the 14+ (K2) gen trucks would go to a 6.2 or something for the big trucks, but they are still using the iron 6.0.
Wish I could. Landlord (wife) says only one unpractical vehicle around the property at once... Good thing she don't know about the pair of rcsb s-10sI just bought for 250bucks.
