Got some more done, got the radiator in and filled, 3 3/4 gallons of antifreeze coolant, thirsty B _ tch.. Did a re-start and roughed in the timing and did the cam break-in. Started "playing" with this new distributor. All electronnic, even the centrifugal and vacuum advance! It all based on engine rpm and under the distributor cap is all circuit board. 3 rotary dials set max rpm, "vacuum" advance & "mechanical" advance, plus 3 settings to lock up all advance and startup advance retard, pretty cool imo..
