The Chevy ZZ572/720R crate engine assembly is all-business, starting with a brand-new, latest-generation block casting with four-bolt main caps and an all-forged rotating assembly for exceptional strength and durability. A unique mechanical roller camshaft with 0.714/0.714-inch lift and 278/282-degree duration specifications complements high-flow aluminum rectangular-port cylinder heads with massive 310cc intake passages, 118cc raised exhaust ports and 118cc combustion chambers, moving big air through the engine efficiently to make huge power!
If you’re building the ultimate dual-purpose car, the Chevrolet Performance ZZ572/720R crate motor is suitable for limited forays on the street. It has a 12.0:1 compression ratio, so make sure you’ve got access to 110-octane gasoline before hitting the local cruise night!
