The time is nearly upon us. The 2023 Corvette Z06 supercar debuts tomorrow, October 26, and you can feel the Chevrolet Performance community jittering with anticipation. Lucky for them, there’s going to be plenty of ways to watch the C8 Z06 reveal. One can watch it from wherever, via the Chevy website. One could make your way to the nearest Chevy dealer that’s likely putting on a reveal party. Or, you could make a trip to LA, and witness the Z06 in person on display at the incredible Petersen automotive museum. Yet even as the storm is about to come to tomorrow, there remains no quiet. YouTuber Emelia Hartford, who was looped in by Chevrolet to help promote the new Z06, teased a video of the supercar’s engine at full pitch on a dynamometer, showcasing its 8,600 RPM redline from its LT6 V8 engine.

By the way, it spits fire.

2023 Corvette Z06 LT6 Engine: 8600 RPM Redline, 5.5L DOHC Flat Plane Crank V8

The 2023 Corvette Z06 will feature a unique engine that shares little to no parts with any other General Motors engine before it. The Chevy team decided that an off-the shelf supercharged LT4 or LT5 V8 simply wasn’t the right fit for the spirit of the C8 Z06, and as a result, the LT6 was born. This screaming V8 features a 5.5L displacement, a flat-plane crankshaft, eight cylinders, and is expected to push out north of 600 horsepower without the assistance of turbochargers or a supercharger.

The LT6 V8 engine has largely been validated on the racetrack up to this point, as a variant of it powers the IMSA championship-winning Corvette Racing C8.R race car. As a result, the architecture of the LT6 has undergone the grueling cycles of a 24 hour race, as seen at Daytona and Le Mans.

The new engine also saw racing action at Spa, Road America, Watkins Glen, Laguna Seca, Circuit of the Americas, Sebring, Mid Ohio, Lime Rock and Virginia International Raceway. The 2021 IMSA Calendar concludes with the 10 hour Petit Le Mans taking place at Road Atlanta in the state of Georgia on November 10, finishing two seasons of validating the LT6 engine architecture.

Now, this info on the 5.5L LT6 V8 engine won’t officially be disclosed until tomorrow, but being as we at MC&T disclosed more information on the C8 Z06 than any other publication out there up to this point (see: the tires, the aerodynamics, and the center-mount exhaust), we figured we might as well keep the trend going.

Be sure to check in tomorrow at noon for all the details surround the fire-spitting 2023 C8 Corvette Z06 and its LT6 V8 engine.

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.
