Big Block Crate Engine - ZZ502/502 Deluxe

The ZZ502/502 is one of the industry’s benchmark crate engines, offering excellent value with a proven combination of performance and all-forged durability that is suitable for the strip or packed clay dirt pullers. With more than 500 horsepower and an amazing 580 lb.-ft. of torque, it will grab your attention!

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 holds above it until about 5,000 rpm. Chevrolet Performance's ZZ502/502 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.

INSTALLATION NOTES

• Clutch linkage bosses are now drilled and tapped. When using cast-iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads, for clearance
• 502 engines now have a mechanical fuel pump boss! (NOTE: There is a fuel pump lobe behind the boss.)
• Comes with an externally balanced 14" automatic transmission flexplate; Use flywheel P/N 14096987 and 11" clutch assembly for manual applications
