Default Chevrolet Performance Adds 6.6L L8T V8 Engine Block To Catalog

Chevrolet Performance Adds 6.6L L8T V8 Engine Block To Catalog

Classic car builders, racers and other enthusiasts will now be able to purchase a GM 6.6L L8T V8 engine block directly from Chevrolet Performance.

Chevy announced the addition of the GM 6.6L L8T V8 engine block to its official performance accessories catalog this week ahead of the start of the SEMA360 online trade show on November 2nd. The automaker says the iron cylinder block can serve as the “foundation for your direct-injected performance engine,” and also claims that it “may see more horsepower than a lightweight aluminum block was designed for.”

The L8T engine comes standard in the 2021 Chevrolet Silverado HD and GMC Sierra HD and is optional in the 2021 Chevrolet Express and GMC Savana utility vans. The 2021 Chevrolet Low Cab Forward 3500 and 4500 cab-over trucks also offer the engine as standard. The V8 serves as a replacement for the GM 6.0L L96 V8 and produces 401 horsepower at 5,200 rpm and 464 pound-feet of torque at 4,000 rpm in fully dressed production guise. It has a 103.5 mm x 98 mm bore and stroke and a 10.8:1 compression ratio.

This product is intended to serve as a foundation for engine builders, with Chevrolet Performance also offering a variety of other off-the-shelf production and specialized performance components to help customers complete the motor. The production version of the L8T V8 has aluminum heads, a forged steel crankshaft, forged connecting rods and variable valve timing.

GM also announced a new Electric Connect and Cruise package ahead of SEMA360, a turn-key electric powertrain with a 200 horsepower motor and 60 kWh battery. It also debuted the Chevy Blazer-E, a 1977 K5 Blazer that appears mostly stock and features this same Electric Connect and Cruise package. While Chevy may be looking to satisfy earth-friendly enthusiasts looking for a greener solution for their classic, the addition of the L8T V8 block to its accessories catalog shows it’s not abandoning traditional customers, either.
