E350 Ford Chassis

Here is the site I found for the 2011 E-350/E-450 Chassis Specifications (along with a lot of additional info). I tried to copy and post but it is much more readable in the side by side format at that site. Every year the numbers change albeit not much. As you can see they are far more alike than different and some of the options, like the 55 vs 40 gallon fuel tank allow for further customization between the two.
