When Ford announced the 7.3L Godzilla V8 engine last year for the F-250 and F-350 Super Duty, the arousal of big-displacement hot rodders could almost be heard. A cast iron block V8 built to take a beating seemed like a desert oasis in an optics-based landscape where rumors of the death of the internal combustion engine is being shouted from every post-modernist rooftop. Not to be outdone, Chevrolet, the deity of crate engines, may have given GM performance enthusiasts just what they were looking for: an L8T V8 option.

Well, it’s just the block. A sweet, sturdy cast iron V8 block. This gives the customer a clean sheet template, opening up a universe of possibilities as to how and what kinds of immense power they can harness for any project this thing will fit in. Currently, this is all Chevrolet is saying about the new offering, ahead of SEMA360:

Chevrolet Performance has introduced a L8T cast-iron GEN V engine block that is very likely completely new to even the most knowledgeable enthusiast. This 6.6L production block is the foundation for your direct-injected performance engine that may see more horsepower than a lightweight aluminum block was designed for.

The 6.6L L8T V8 can currently be found in the 2021 Chevrolet Silverado HD as well as the 2021 GMC Sierra HD as the standard engine. Pushing out a stout 401 horsepower at 5,200 RPM and a stalwart 464 lb-ft of torque at 4,000 RPM, the L8T makes just over 11 percent more horsepower and over 21 percent more torque than the 6.0L L96 V8 it replaces.

By comparison, it’s a little down from the Godzilla V8, which pushes 430 hp and 475 lb-ft of torque. But the Godzilla is an optional engine, where the L8T is standard. Ford still has its 6.2L gas V8 engine as the base unit for its Super Duty trucks. It produces 385 horsepower and 430 lb-ft of torque.

We hope to have much more on this exciting new addition to the Chevrolet Performance catalog in the coming days, as SEMA360 ramps up from November 2-6, 2020.

Muscle Cars & Trucks was founded by Manoli Katakis - an automotive media veteran that has been covering the latest car news since 2009. His journalism has uncovered dozens of major product changes, updates, plans, and cancellations long before automakers were ready to make things official.

Some highlights over the years of his reporting include the uncovering of the Zora trademark before anybody else reported on the coming of a mid-engine Corvette, as well as the dead-accurate reporting of the coming of the Chevrolet Colorado ZR2, two years before it hit the market, and even before the debut of the concept vehicle. This type of reporting has immediately continued here, with reports of the original seventh-generation Camaro plans being shelved, as well as what's in store for the Chevrolet Silverado.

Some of his work can be found on massive automotive media outlets, such as Motor1. He also has been a guest on the 910AM Radio Station with Detroit News auto critic Henry Payne, as well as the enthusiast-oriented Camaro Show podcast.

Over the years, Manoli has interviewed various automotive industry titans, leaders, and people that make things happen otherwise. These include figureheads such as GM CEO Mary Barra, GM President Mark Reuss, automotive aftermarket icon Ken Lingenfelter, Dodge firebrand Tim Kuniskis, along with various chief engineers of vehicles such as the Ford F-150 & Mustang, Chevrolet Camaro & Corvette, and many more.

At MC&T, Manoli is taking his journalism expertise, deeply planted sources, driving abilities, and automotive industry knowledge to new levels, covering more vehicles and brands than ever before. This is the place where you will continue to read groundbreaking stories about American performance vehicles, pickup trucks, and sport utility vehicles. Here is where you’ll also read insights and quotes from various automotive subject matter experts on the latest relevant products, as well as some of the latest official news from their manufacturers.

Fun facts: he also once beat Corvette Racing driver Tommy Milner in an autocross with a Chevrolet Bolt EV. The biggest vehicle he’s ever driven is a John Deere mining truck. Besides a go-kart, the smallest vehicle he’s driven has been a Hyundai i10. He’s also spent time in the cockpit of various American performance vehicle icons, including the fifth-generation Chevrolet Camaro Z/28, Dodge Challenger Demon, and Ford Mustang GT350R. He has reviewed dozens of trucks, SUVs, and performance vehicles over the years.

One of his favorite new vehicles on the market today happens to be the Chevrolet Colorado ZR2 Bison. He is also a card carrying member of the Sports Car Club of America, and regularly participates in Detroit Region autocross events.
