Electronic ignition question

A follow-up. The distributor on the Fury does not have a vacuum advance pod on it. Does this mean that it was originally a lean-burn system on the car? I am not sure what was meant by the breather can that Redfish mentioned.

So now, what distributor would y'all recommend. Please keep in mind this is just a driver - no racing, not even... future plans may include an MSD box after it is running right though.
Thanks,

pick up a distributor from a dodge truck from the years of 1976 or so up to 1985 that way your guaranteed the distributor you want trucks come factory without lean burn, infact the ones from napa work nicely and there only around $60
