buick 231 even fire motor with odd fire points distributor..

just got this 1970 cj5 motor had been changed to a buick 231 even fire according to the engine code. it has a points distributor with what i belive is a odd fire with a even fire cap! also i was told it has a mild cam installed so.... i have the old cam and also a hei even fire he was going to throw in but its not vac. advance its elect. advance, so i was thinking it may have been the stock distributor but now this motor has no computer to control it.
so if the stock cam was even fire could they have intalled an odd fire cam on accident? then used this points setup to fix the problem?
would a even fire motor run decent with a odd fire distributor?

If it runs well, then maybe the cap is the exterior change needed? Just a guess.

thats what i was thinking. does anyone have pics of a odd and even fire points distributor? i know its supposed to be even spaced lobes for even fire but its hard to tell without pulling it out. iam sure its an even fire cap. and from what i see this never should have had a points distributor.
