Don't wait weeks or months for a custom drag race engine. The ZZ572/720R is the king of all Rat engines from Chevrolet Performance! Make no mistakes, this engine is built and intended to propel your bracket racer down the drag strip with ferocity. The ZZ572/720R is fully assembled by the horsepower gurus at Chevrolet. You simply bolt it in, add fuel and power. Its ready to rumble.

The 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 .714''/ .714'' lift and 278°/ 282° duration specs works great with the 310cc rectangle intake ports, 118cc raised exhaust ports and 118cc combustion chamber aluminum cylinder heads. Moving big air through the engine efficiently makes huge power!

If you're building a dual-purpose street and strip car, the ZZ572/720R is suitable for some limited street prowling. It has a 12.0:1 compression ratio, so make sure you've got access to 110-octane fuel before hitting the local cruise nights!
