The Classic 454 Big-Block topped with Aluminum Heads and Intake, Mated to a Stout 6-Speed Gearbox!

The Chevrolet Performance engineers started with the tough 454 HO and added a set of better flowing, lighter weight, oval-port aluminum cylinder heads to pick up 15 additional horsepower. Don't worry though, that meaty torque is still there – all 500 foot-pounds of it! It is all housed in the latest-generation block casting with four-bolt main caps that contain an all-forged rotating assembly for superior strength and durability. The ZZ454 is an affordable high-performance Big-Block Chevy ready to take your hot rod project to the next level. The 4L85-E four-speed overdrive transmission channels that Big-Block torque with exceptional strength and precision, while keeping the revs manageable for highway cruising.

The Connect & Cruise lineup even includes several emissions-compliant E-ROD systems in both automatic and manual.

We did the work to design and calibrate perfectly matched powertrain systems and covered them with a 24-month / 50,000-mile limited warranty.
