“Our next generation LS6 engine pushes 409 cubic inches of jackhammer fury through the tailpipes,” Mike Kociba, assistant chief engineer on the Next Generation V8, boldly said. “Combining large displacement, modern technology, and proven Small Block V8 heritage will deliver a bold new chapter in performance.”
The Next Generation V8, debuting with the 2027 Corvette, is bigger, more powerful and more durable, according to Chevrolet.
It displaces 6.7 liters over the 6.2 of the Corvette’s predecessor powerplant, the LT2. It delivers 535 horsepower and 520 lb.-ft. of torque over 490 horsepower and 465 lb.-ft of torque. A new lubrication system, forged pistons and rods, and revised exhaust manifolds improve durability in extended high-load, high-temperature environments, Chevrolet says.
Other changes, the Next Generation V8 uses dual fuel injection (port and direct) rather than just direct. The throttle body increases from 87 mm to 95 mm, and the engine incorporates a tunnel-ram intake with high-velocity ports, all of which increase airflow into the V8.
The new next-generation LS6 remains naturally aspirated, with the automaker saying it produces more torque than any other naturally aspirated V8 before it.

Is “jackhammer fury” the new name for “engine self-destruction” that GM has been providing as a recent feature?

I'm not sure I'd have chosen those words. "Jackhammer Fury" does nothing to suggest smoothness.
Nope, the rocker covers are wrong.

Quite the opposite, actually
I sense an advertising tie-in featuring The Beach Boys: “Giddy up, giddy up 409….”
Nice to have both port and direct fuel injection.

Makes me think of a 12v Cummins.
The 318 in my Power Wagon sounded like it had a case of the "Jackhammer Fury" right before I yanked it for my 360 Magnum swap. Pretty much every bearing inside that engine was smoked. It sounded like a busy blacksmith shop, or, like a current gen Chevy V8 trying to idle into a dealer service bay. They definitely could have chosen better words there.
That said, if they fixed the premature explodey issues with better oiling and dual injection, that's cool.
So is it a pushrod or DOHC motor? That didn't seem to be explicitly clear in that release and they've been playing with both on the C8 platform.

Flathead. Better displacement to external volume ratio.
