Who we are and what we do...

440 Source is an American owned and American run family business. We are located in Lancaster, California (about one hour north of Los Angeles.) We are now in our fourth location, a two story warehouse with a combined total of over 10,000 square feet of space. At any given time, we keep in stock hundreds and hundreds of crankshafts, connecting rod sets, pistons, and 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.

Believe it or not, we have been in the "big block Mopar only" business since 1992. We first started out (originally under a different name) as a core supplier of used engine parts specifically for the big block Mopar engine. This was back in the days when building a high performance big block Mopar meant rebuilding and/or modifying used factory parts. Hardly any new aftermarket components (cranks, rods, heads, etc) were on the market, and the ones that were available were often priced so high, they were well beyond the budget of  98% of people interested in building a high performance engine. Many of the well known machine shops and warehouse stores offered high performance engine kits, either as "long block" or "short block" kits, or early "welded" stroker kits, where shops would take a stock Chrysler crank and weld extra material on the outside of the journal, and then offset grind the crank to increase the stroke (and therefore the cubic inches) of the engine.  

Throughout the mid 90's, we built up a nationwide distribution network, and a large percentage of the original factory parts for the early "welded" stroker kits and 440 block kits being sold by well known nationwide shops and warehouse stores were getting the parts they were using from us. Here's some pictures from one of our older locations:

Head storage racks.

Misc Blocks, water pump housings, crankshafts, intakes, etc.

Some older short blocks in storage waiting for teardown.

And, core engines out back during during teardown.

As the years passed, it became increasingly harder to find used factory engine parts for an engine that had been out of production for over 2 decades. At the same time, the aftermarket was starting to fill the void with much higher quality performance parts, and the cost was coming down to a point where it made building a high performance engine from aftermarket components a realistic proposition for those of us who don't get driven around by a chauffer.

We started to rethink our business model, and in 2002, we decided to add a division to our wholesale core supply operations. We saw a need for a retail mail order warehouse, specializing in sourcing and/or manufacturing the highest quality, lowest cost parts available for the big block Mopar engine. We called this division 440 Source, and by 2003 www.440source.com was online. Because we keep our overhead costs low, (combined with our large buying power,) we are able to supply very high quality parts at what seems like unbelievably low prices.

While we have grown steadily over the years, we still remain a family owned and run business. We are as passionate about America and the big block Mopar engine as we were when we first started in 1992. We'll never get greedy and start selling small block Chevy parts. We provide a level of quality in our engine components and specialty service the big warehouse stores could never dream of. This isn't just some job for us. Give us a call and you'll see for yourself. You won't find some kid on the other end of the line reading off random part numbers they know nothing about. We don't just sell Mopars, we own 'em, we race 'em,  and we work on 'em. We know our parts and cars backward and forward, and have for many, many years. We look forward to serving you now and long into the future, as we expand our product lines and release many more new, exciting and affordable parts for the big block Mopar engine.
