Larry, I had previously provided information on Newells with 600+ HP engines based on your specifications. Bill is correct that torque is as important or more important factor than horsepower. Another consideration is vehicle weight. The GVWR on a P2000i is 63,600. A 2002, 2000 model had a GVWR of 55,000 so the lower horsepower (typically 500) and torque (typically 1550) of the Detroit Series 60 is about half offset by the weight difference.
If you back into the Newells with the 500 HP engines (predominately Detroits), changes include:
During the 2003 model year Newell changed from using HWH hydraulic slides to Valid electric slides,
In the 2004 model year Newell changed to the ZF suspension with the steerable tag.
During the 2005 model year Newell changed from the 2000 series body style to the 2000i (enhanced) body style.
