ZZ454/440 (MUST CALL TO ORDER AND TO GET CURRENT PRICING) - Classic Muscle (12498777)
- Product ID: 12498777
Chevrolet Performance Parts took the venerable 454 HO, swapped the cast iron production heads for a set of oval-port aluminum castings, and created 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. These oval-port aluminum heads use huge 2.25" intake and 1.88" exhaust valves as well as small combustion chambers to add to the efficiency of the 454" big-block. The bottom end includes a Gen VI four-bolt, a forged steel crank, forged connecting rods, and forged pistons. A roller camshaft with a .510/.540" lift specs deliver a big-block loping idle as well as add to the high performance punch of the entire crate engine.
The ZZ454/440 is delivered as a complete assembly including water pump, balancer, intake manifold, and 14" automatic transmission flexplate. All you need to do is add your carburetor, ignition, and starter to complete the project.
