CnP = Coil-Near-Plug. Similar to G3 hemi which has coil-on-plug.
Andy's setup will have the coils mounted near the plugs (maybe on the valve covers or located in an array on a bracket somewhere) with short plug wire leads for each.
Essentially, there will be 8 coils with short plug leads, 1 for for each cylinder.
Yep, I'm still trying to figure it out. For the dyno engine I think I'll mount the coils on brackets on the valve covers. In the car I might put the coils on the frame rails or something like that.
The nice thing about the CnP setup is that you get rid of the MSD box, the big coil the distributor and a bunch of ignition wires. From a performance standpoint, each coil only has 1/8th of the job that the big coil had before. At 7000 rpm and 15:1 compression the MSD ignition had to really work.
