Big black Distributor

I wonder if anyone has used a Mopar electronic distributor from a newer car with the original box form a 1970.  Are they compatible or do I need to replace the box as well?

The Box will work with any Mopar electronic dist .
You may get better response or higher RPM capability with a different ECU though such as Rev-n-Ator

If I don't have one in my stash my MO is to get a 75 440 distributor from the parts store, check the bushings, weld up the slots to shorten them and install light springs. Good to go for cheap. I've never spent big bucks on a distributor in my life.
