Current Stock:

Whether you use it for your drag car or competition pulling truck, the value-driven 502 HO crate engine offers affordable performance. It’s rated at 461 horsepower and 558 lb.-ft. of torque, for pulling power that exceeds anything ever offered from Chevrolet’s production Big-Block engines. It’s real power that only comes from a Big-Block!
To support all that torque, we built the 502 HO with a brand-new, latest-generation block casting with four-bolt main cap. We complement that with an all-forged rotating assembly for exceptional strength and durability, while a hydraulic roller camshaft is used for excellent drivability and a broad performance range. Our crate engine assembly includes an aluminum, dual-plane intake manifold, a water pump, 14-inch flexplate, balancer and more. You add the carburetor, starter and
ignition system—all available from Chevrolet Performance.
