One of the reasons i love DC is because they almost always deflate thier hp and torque numbers.
DC correctly rated the HP numbers of the 4.0 but they did underrate the torque by about 15lbft. The early HO 4.0 XJ should have been rated at 190hp/240lbft and the later one slightly higher, but definitely not 210hp. A '00 XJ is not quicker than a '92 XJ so I think the 210hp claim is just wishful thinking.
As for other Jeep engines, DC correctly rated the 4.7 V8 for HP and underrated it for torque, underrated the 5.9 V8 for both, and correctly rated the 5.2 V8 for both.
They didn't underrate every engine though. They somehow managed to grossly overrate the 3.5 V6 in the Chrysler 300M. They rated that one at 253hp but the performance suggests that it has about 30hp less than that.
