Well, I must admidt, I was not 100% sure if the 2500 would have the "upgraded" Hemi, but in my mind I thought it should. Today the 1500 reg cab and HD trucks are built under the same roof, back in 09 though I do not think they were, was just another factor though in my thinking they would not have two engines. I googled, and while I do not trust the source I tend to believe this is correct and means, yes, it would be the newer Hemi. Numbers just slightly smaller than the 390/407 1500 numbers. Probably a tune thing.

Pull the hemi hat and snap some pics of it, we will be able to tell from that.

 

From this link, below the summary is a link to "read more" and on that page it states...

New for 2009

With a new truck coming for 2010, Dodge trimmed down the Ram's heavy-duty lineup for 2009. The Power Wagon is available only in Quad Cab. The Hemi has been upgraded to 383 horsepower and 400 pounds-feet of torque for 2009, but that engine is no longer offered in 3500 models. The Hemi also loses the six-speed manual transmission; it now comes only with the five-speed automatic. Other changes include remote start available on diesel vehicles, limited-slip rear axle standard on 3500 models and larger front and rear brake rotors for all models.

So your ahead of the 2008, just a wee bit behind the 2010 according to this.
