Chevrolet Performance 19433410 - ZZ454 Crate Engine

The ZZ454 packs a serious punch. Chevrolet Performance installed a set of high flow racing inspired oval port aluminum cylinder heads on top of a fully forged 454 cubic inch shortblock and the results are nothing short of awesome - 469hp and 519 lb-ft of TQ! You should note that it's all build on a latest generation 4-bolt main block - so you know it is strong. The high lift hydraulic roller camshaft provides a broad TQ curve with excellent street manners.
