AN AFFORDABLE POWERHOUSE!
What will you do with 461 horsepower and 558 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, we build this Big-Block with our latest-generation block casting with four-bolt main caps and complement it with an 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 gasoline at all altitudes and engine loads.
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.

PRODUCTS ON OUR SITE should be viewed as a Catalog of Genuine GM OEM Auto Parts & Accessories. They are subject to availability and may be discontinued or have a superseded number without us having been updated by the manufacturer.
Some Parts are “On-Hand” or “in-stock” and come from our physical location. Others are sourced from our direct GM suppliers. On occasion, some items become unavailable or are understocked without our knowledge. GM provides us with updates continually, but this is not always reflected immediately on our store site.
We make every effort to communicate with you via email regarding any questions, updates or changes about your order throughout the process. If an item cannot be supplied, you will not be charged or a refund will be applied for that particular part or order as needed.
Shipping prices quoted on your final order may be subject to change based on actual packaging box size + delivery logistics. The dimensions x weight seen on a product page is for the actual part or accessory itself, not necessarily the packaging box used. This can affect the later shipping rate calculations. We make every effort to give you the best rate on your order and will consult with you on changes.
Orders with a VIN number provided are recommended and verified for accuracy.
