Picked up this cap the other day and was trying to figure out what it fit. I had a assortment of rotors and believe this may be for it, what's your thoughts? Thanks.
Nash twin 8? https://www.jalopyjournal.com/forum/threads/nash-twin-6-and-twin-8-distributors.1166797/
Fire trucks back in the day had redundant ignition systems so you could switch from one to the other, but usually had twin distributors.
Never seen a 16 on a Fire truck, but 12 were very common! All the trucks I worked on had twin distributors. And you could run on one or the other or both. The neat thing is you could check the condition of either system , by noting the rpm on #1 then switching to #2, if the rpm stayed the same, both systems were in good shape! Kinda back yard check. But….. every time I would switch to “ Both” systems , the rpm would increase! I guess that kinda proves two plugs per cylinder are better!?!?! Also notice that the rotor bug has two….” Thingys” ! That means that it either ran an eight cylinder with two plugs or two eight cylinder engines , trying to run identical! Also notice that they are not exactly 180 degrees apart! Bones
