I don't try and keep all the small block nomenclature in my head. This new one is of course still "push rod", which is a thing I find rather interesting. Nearly everything now of course is DOHC, I realize the PR has some advantages.

I kind of agree that this GS version might be a value sweet spot in the range available, which now is almost ridiculous. I'd still like a manual, but whatever.

I might have named it the LS67

the LS6 is the most powerful naturally aspirated V8 GM has ever produced, other than the flat-plane DOHC marvel under the glass of the LS6’s current Z06 stablemate, but that’s graded on a different scale. Even with all of the above bragging rights, horsepower isn’t even the LS6’s most impressive trait. That distinction, if you missed the title and opening quote, goes to its massive torque figure.

The LS6 torque curve peaks (“peak” is used lightly, here, because we’re talking about a mostly flat line) at 520 lb-ft. Chevy claims that’s more twist than any other free-breathing production V8 ever made, and we’re going to put that statement to the test below, but the fact that it equals the first (LB7) Duramax’s – which is a diesel with a turbo built for effortless torque-y towing – torque rating means Chevy should be pretty confident in its boast.

Well, you know the purists. "If it's not a front-engine RWD push-rod V8, it ain't a real 'Vette!"

They could only change one of those at a time. Baby steps, you know.

The sole advantage of pushrods I've ever read is it's shorter in the bay, the DOHCs are toller and need more space.

I'm amazed they can get this kind of power using pushrods and 2 valves per (with no forced induction).
