LS3 495hp T56 6-Speed Manual Connect & Cruise Package



Chevrolet Performance’s innovative Connect & Cruise factory-matched engine-and-transmission combinations reduce the time and hassle of picking the parts to power your project vehicle.

Each system matches one of our performance Small-Block, Big-Block and LS/LT crate engines with a complementing transmission, as well as the supporting calibrated controllers, torque converters (for automatic transmissions) and installation kits.

With Chevrolet Performance’s Connect & Cruise combinations, it’s never been easier to pick your project powertrain!

Mixing the capable LS "Hot Cam" with the powerful 6.2L LS3 takes affordable performance to a great, new level - 495 horsepower and 475 lb.-ft. that will wake up your vintage Camaro, Chevelle or "shoebox" Chevy. The T56 Super Magnum Six-Speed Manual Transmission backs the LS376/480 with strength and durability. Put this combo to work in your classic cruiser and enjoy a great balance of performance and efficiency!
