According to FCA, they did not change the pump from a CP4 to a CP3. They did, however, change the from an asymmetrical to a symmetrical cam design. A CP3 would not look identical to a CP4.

Drivingline article on 2021 Cummins
TFL says 400 horsepower, Drivingline says 420 and Ram says 430. They all say 1075 lbft of torque but no one says at what rpm max torque is produced. Then on the Ford side some Ford publications say peak HP is obtained at 2600 rpm whereas other Ford publications say 2800. the same goes for peak torque ... is it 1600 or 1800? If these numbers are so important you'd think they would get there ducks in a row before publishing them. They used to publish torque curves. At least if they gave us rpm along with peak torque and power values we could speculate what the torque curve looks like.
