ALUMINUM HEADS ADD BIG POWER!
Our engineers took the tough 454 HO and matched it with a set of higher-flow, oval-port aluminum cylinder heads
to pick up an additional 30 horses – while still delivering an awesome 519 lb.-ft. of torque. It’s an affordable high-
performance Big-Block for your project vehicle!
Aluminum oval-port cylinder heads with 2.19/1.88-inch valves process the airflow through this big-power Big-Block
and save weight over iron heads. They’re mounted on our latest-generation block casting with four-bolt main caps,
which is filled with an all-forged rotating assembly for exceptional strength and durability. There’s also a high-lift
hydraulic roller camshaft for excellent drivability and a broad performance range.
The crate engine package includes a water pump, balancer, aluminum intake manifold and a 14-inch flexplate. Your
Chevrolet Performance dealer can hook you up with the carburetor, starter, ignition system and other accessories
required to get this big-power Big-Block up and running.
