Who we are and what we do...

440 Source is an American owned and American run corporation. In business since 2003, we have recently moved to our fifth location, a 10,000 square foot warehouse in Carson City, Nevada. Our warehouse is filled with floor to ceiling shelving racks of nearly every part you could need to build a big block Mopar engine. We are the only business in the world with an entire warehouse dedicated to nothing but big block Mopar parts.

Informational Pages:

Below are pages we have setup for informational purposes, covering factory original parts. Many of the pages contain pictures of the parts, as well as tables which list the original factory part numbers, and what years and engine sizes those part numbers were used for. Many of the parts listed in these pages below are available from us in new reproduction versions.
