GM HEI on Mopar,Does it work?

interesting thread here on HEI vs the Mopar module.
I have seem most of the HEI conversion threads, but have not made a change yet,

fishy68,,, what HEI upgrades do you recommend, any particular coil work well with HEI?

dgc333,,if I go with a Mopar system,, what are good coil options , with / with out a ballist resistor?

motor is ( will be ) a warmed slant six, I have a slant electronic / vaccum distributor, to start with, but I am open to suggestions there to.

thanks
