The basic premises of the article, eerily reminiscent of being 2007 all over when GM sold both old and the then new body style concurrently. What’s interesting is the engine choices as quoted below.

Familiar engines return to the next-gen Silverado. There’s the fifth-generation 4.3-liter V6, two 6.0-liter V8s (gas and CNG), and the 6.6-liter Duramax diesel V8. Silverado Legacy buyers, however, aren’t lined up for much choice. Going old means an extended cab bodystyle and a 5.3-liter V8, rear- or four-wheel drive, and trims limited to Work Truck (fleet/base), LS, and LT.

So by reading that, the reader would assume the 5.3 offering is no longer in the new 2019 truck, being replaced with a singular 6.0 V8 offering. So the 6.2 is gone as well. Which would make sense as in the market segment the truck competes in the 5.3 is out gunned by most all other competitors V8 offerings sans the Toyota 4.6. The optional 6.2 V8 makes more power than the other V8s, but the bulk majority of these trucks leave with the 5.3 V8.

The posted 2019 VIN cards are just an initial set. They're continuously updated as the model year draws closer.

Doesn't make sense. I would assume that GM would develop smaller v8s, instead of only going with one 6.0L. Don't get me wrong, its a good engine along with the 6.2, but the 5.3 is also an excellent engine that they've had awhile. The 5.3 is also better with gas mileage.

The 6.0's are for the HD's. The 1500's get the 6.2....

Why do hd's get the lesser v8?

I think the main reason is that the bigger engine can use AFM more often. There will be a lot of times when a 3.1L V4 could move the truck while a 2.65L V4 couldn't.

The 6.0's are still the Gen IV Small Block. Also not sure if they are an Iron Block or eventually GM changed it over to the aluminum block version. Probably all have to do with cost.

Its not a lesser V8 (6.0 in HD), its much more durable than the 6.2 1500 engine.

Peak power output maybe less, but the 6.0 meets a durability spec that the 6.2 likely couldn't come close to.

The 6.0l is one of the best engines ever built if you ask me. Ive had many of them used as service vehiles over the years. They are bulletproof. Probably one of the most underrated engines out there.

6.0s are less compression as well compared to the 6.2s, it's a work truck engine through and through.
