Engine - GM (19433162)
OUR MOST POPULAR BIG-BLOCK
The ZZ502/502 is one of the industry's benchmark crate engines, offering excellent value with a proven combination of performance that is suitable for the street or strip. With more than 500 horsepower and 580 lb.-ft. of torque, it demands your full attention and a chassis that is strong enough to harness its frame-straining twisting power.
Thanks to a combination of high-flow aluminum oval-port cylinder heads with 2.25/1.88-inch valves and a hydraulic roller camshaft designed to support low-rpm torque production, this torque monster tops the 500 lb.-ft. mark by approximately 2,500 rpm and doesn't dip below it until about 5,000 rpm. It also features a latest-generation block casting with four-bolt main caps and an all-forged rotating assembly for exceptional strength and durability.
Our Deluxe package comes complete from the oil pan to the carburetor, including an HEI distributor, plug wires, starter, water pump, balancer and an aluminum intake topped with a Holley 870-cfm four-barrel carburetor.
