Marvin Sambur, the Air Force's top acquisition official, wrote to the investigators that the program is within its cost, schedule and contract guidelines. Lockheed Martin has started delivering planes which meet Air Force specifications and the necessary upgrades have either been completed or scheduled, Sambur wrote.
While some of the facts presented in the DOD/IG report are accurate, the findings and conclusions ascribed to these facts cannot be supported," Sambur wrote in response to the inspector general's office. "The Air Force fully endorses the C-130J program."
It sounds like the USAF are complaining here on the C-130J, and they are the customer are they not?

The customers, if not happy, are satisfied. That includes the foreign ones too, and they have used them in combat support roles in Iraq.

<i>The new C-130J has the familiar silhouette, but it is a brand new airplane with the performance to prove it. Compared to the earlier production C-130E, maximum speed is up 21%, climb time is down 50%. Cruising altitude is 40% higher, range 40% longer. With new engines and props, the J can reach 28,000 feet in just 14 minutes. And for tricky low altitude maneuvers, new avionics and dual head up displays make it easier and safer to operate. It also offers reduced manpower requirements, lower operating costs, support costs, and life-cycle costs.
While continuing to upgrade through modification, the Air Force has budgeted to resume fleet modernization through acquisition of the C-130J version. This new model features a two-crew-member flight system, 6,000 shp Allison AE21 00D3 engines and all-composite Dowty R391 propellers, digital avionics and mission computers, and improved reliability and maintainability. </i>

I don't think it is possible to substitute the T-56 for the AE2100D3 engine. There are too many differences.
The J model also holds many obscure aviation records for its class. It is a big improvement over previous models.
