Big Block V8 502 Crate Engine - GM (19433156)

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 They are subject to availability and may be discontinued or have a superseded number without us having been updated by the manufacturer.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. 

Any illustration is a simple rendition of the part and where it is located on the vehicle; it is for reference only. Factors such as trim, color, and options are not depicted in the illustrations. Check with us if a part or accessory stock photo shows a color style to make sure what is ordered will be that color.

Product descriptions may say “Left” or “Right”.  Left=Driver’s Side | Right=Passenger Side

We work constantly to update our site for accuracy, but some items displayed such as large auto body parts, hazardous materials, heavy parts and other delivery-dangerous products may not be available for shipping. We will email you about anything you ordered which will be too difficult to send safely and refund any order made in error.
