Free Shipping!

What will you do with 450 horsepower and 550 lb.-ft. of torque from Chevrolet Performance's value-driven 502 HO crate engine? Whether you use it on the street, strip or even pulling a trailer with your workhorse truck, its performance range offers unlimited possibilities. In fact, it makes nearly 500 lb.-ft. by only 1,500 rpm, meaning it has all the low-rpm grunt you can use! To support all that torque, this Big-Block starts with the latest-generation block casting with four-bolt main caps and built with all-forged rotating assembly for exceptional strength and durability. A hydraulic roller camshaft is used for excellent drivability and a broad performance range; and an 8.75:1 compression ratio is suitable for regular pump gas at all altitudes and engine loads. This crate engine assembly includes an aluminum, dual-plane intake manifold, a water pump, 14-inch flexplate, balancer and more. You simply add the carburetor, starter and ignition system.
