It may look unassuming, but strap this new 440 Hemi in your car and find out otherwise.
It's a statement made by non-Mopar wannabes for as long as many of us can remember: "Yeah, that's a 440 Hemi, my dad had one of those." OK, maybe it's not exactly like that, but we've all heard mention of a 440 Hemi by someone. What would you say if I told you that we now have to be careful how harshly we correct the people that make that statement?
The newest version of the Hemi was always a well received engine, and the aftermarket has really started to embrace it and make a lot of good, performance-oriented parts for it. A couple of reputable engine builders have even come up with crate engine versions that feature more stroke, and better-than-OE parts. But still, a 440 Hemi?
Arrington Engines in Martinsville, Virginia, has been affiliated with Mopar racing for a long time. It all started with Buddy Arrington wanting to go fast, and ending up starting a career in NASCAR, where he had a 25-year storied career. Following in Buddy's footsteps is his son Joey. Joey learned early how to make power with a Hemi engine, and when the Third Generation of the Hemi was born, Joey continued to find ways to make the latest version a true performer as well. With that said, let's say your Magnum, Charger, 300, or even your new Challenger has served you well, but now that you've driven your car for a while, you realize it's time for more power-it happens, we understand. Well, all you need to do is call Arrington's and order your 440 Hemi at a special price with no core charge. What you get is 575 hp in a box shipped to your door that is ready to drop in your project with everything you need from the wiring harness and sensors, all the way down to the dipstick. This 440 is built from all-new components, including the NASCAR-grade prepped 6.1 block. Well, enough with the explanation about what it is, let's get into what's in it.

The heart of making 440 cubes...
The heart of making 440 cubes is the stroke. Arrington Engines uses only quality parts proprietary to them, to make this all happen. One of the things the AE does differently than many, is done during the balancing of the crankshaft.
Instead of drilling holes...
Instead of drilling holes in the counter-balances, the crankshafts are placed in a lathe, and metal is removed from the counter-balance. This not only lightens the crankshaft, but makes room for stroke.
The small ends of the H-beam...
The small ends of the H-beam connecting rods are bushed, and we all know the benefits of bushing rods and floating piston pins.

We just thought we would show you this image to give you an idea of the difference in rod length between a new 440 and a new 426 late Hemi. Yep, Arrington also manufactures Third Gen Hemis into 426 cubes.

The forged pistons are also proprietary to AE, and feature support gusseting.

The pistons are lightweight, and the top ring land is located lower than on a stock piston...

Each engine is hand assembled, and here one of the guys is torquing the crankshaft in place.

It's a time consuming process, but all aspects of the 440 build are done by hand, and file fitting the rings for each cylinder is part of that process.
