The 5.7 2009+ and 6.4 2011+ are both VVT engines which have the timing set spaced further from block face and use thicker timing covers to accommodate the the VVT setup. All 6.1 cranks will work in ALL engines with 2 caveats,
For use in VVT engines, you need a crank sprocket spacer.
Also 6.1 cranks use a unique to them,4 bolt IIRC, trigger wheel that you need to make sure has the right tooth count for your type of engine management.
To use a VVT crank in a non VVT engine you would have to have it machined to let the crank sprocket seat deeper on the snout.
