Hello,
I'm slowly starting to go through my relatively stock 440-6 setup in a '70 Super Bee. The only modification I know that it has the "silver box" Mopar electronic ignition. I am not too familiar with all of this, but am learning.

A mechanic I know told me that I should think about adding a MSD ignition box to this setup. He said that without it, getting the proper distributor timing (or curve??) to run the six-pack well would be a lot harder.

I'm not familiar with MSD systems. Can anyone shed some light on whether they would be beneficial to a 440-6 setup like mine? Any downsides to them or special tuning requirements when using one?

Also, if not using MSD, are there improvement suggestions to the distributor itself for a 440-6 with Mopar electronic ignition?

Thanks very much!
