In today’s age of aluminum engine blocks and high-tech valvetrains, the naturally aspirated 6.6L V8 L8T gasoline engine is seen by some as the last breath of American iron-block engines. Generally speaking, iron blocks can handle more power than their aluminum block counterparts, making them the choice for high-horsepower applications. With this in mind, Lingenfelter recently announced on social media that it’s working on a supercharger system for compatible Chevy Silverado HD and GMC Sierra HD models.
In a post to Instagram, Lingenfelter revealed that it has a 2024 Chevy Silverado 3500 HD High Country getting fitted for a supercharger as part of an upcoming package. In the description, the aftermarket tuning company commented that heavy-duty pickup truck was receiving a TVS2650 supercharger. Unfortunately, no power figures were detailed.
It’s worth noting that Lingenfelter offers a TVS2650 supercharger for the Chevy Silverado 1500 and GMC Sierra 1500. When equipped with the 6.2L V8 L87 gasoline engine, this combination develops 650 horsepower and 630 pound-feet of torque. As such, it would stand to reason that the Silverado HD and Sierra HD models would produce more power.
As a reminder, the naturally aspirated 6.6L V8 L8T gasoline engine is rated at 401 horsepower and 464 pound-feet of torque from the factory, and is standard across the Silverado HD and a majority of the Sierra HD lineup. The optional 6.6L V8 L5P turbodiesel Duramax engine, which has been uprated to 470 horsepower and 975 pound-feet of torque for the 2024 model year, stands as the only other powerplant option.
In conjunction with the 2024 Silverado HD and 2024 Sierra HD, the L8T is paired with the Allison-branded 10-speed automatic as standard fare. Previously, it was mated to the GM eight-speed automatic transmission.

If you need more torque, buy a diesel!
They should make the SC intallation for the Blazer
more available in the shop instead.
They need to put a whipple on the duramax. Banks Lockjaw concept was incredible and it eliminates most the issues with the duramax. Better power, quicker response, even less fuel consumption. Simpler, awesome sound. Would be cheaper from the factory and lighter with less required cooling.
The L8T was previously mated to a six-speed automatic transmission, not an eight-speed that was cited in this article.
Plenty of room in the engine bay for it.
