Ala the  Mallory special-perf dual-point/dual-coil...?   Got one of 
them  too, for a 383 Mopar, not sure what I'll ever do with it.   I'd  
run it on Ebay if I thought anybody would buy it.   Interesting  
sucker, 4-lobe cam with gentle slopes, lots of dwell time, probably  
turn 7500 rpm and not float a point set.     I understand  Mallory 
made one of these dual-coil/dual-point setups for a Corvair engine  at 
one time.   Not seen one but I'd like  to.

With the early Mallory Dual Point, both sets of points fired one coil, they  
just alternated. The three lobe cam was strange. Setting the dwell was  always 
a series of compromises. Changing the point gap on one set changed  the 
firing point - relative to the other set of points. You had to check the  timing on 
cylinder #1 then again on cylinder #2. It was easy to have one side  set at 
12 degrees BTC the other side at 16 degrees BTC. The was a piece of  hardware 
begging for a distributor machine, usually called a Sun machine, mine  was an 
Allen brand. - Seth
