    The Chevrolet Performance ZZ454 was developed taking the venerable 454 HO, swapping the cast iron production heads for a set of oval-port aluminum castings and creating the ZZ454. Not only do the aluminum cylinder heads flow more air, but you also drop almost 100 pounds off the nose of your car dramatically improving performance. The aluminum heads of the ZZ454/440 account for 15 horse improvement over the iron-headed 454 HO. The bottom end includes a Gen VI four-bolt, a forged steel crank, forged connecting rods, and forged pistons!
