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.

GASP! 😱
What could it be?
Yes, we have received two blocks. These are the prototypes that just arrived this morning, fresh from machining. We understand that everyone is excited, and we are too. Thank you for being patient while we make sure the QC is right on point. We will be installing cam bearings, intermediate shaft bushing, checking lifter bores, etc. and we will post another update soon. We are probably looking at 2-3 months until we have stock on the shelf which you can order. Sorry, we aren’t taking pre orders until we can deliver. We do have a waiting list if you want to call and add your name to it.
