Any truth to mounting a Coil in a vertical position? Were the factory Coils oil filled like these aftermarket ones. Just picked up a Accell 8140 (yellow) Coil and I'm wondering about positioning
I never knew what original coils were, oil or epoxy filled. I would assume old cars like ours were oil filled. I recently had trouble with an oil filled that was horizontal. I replaced it with an epoxy filled coil. The only Mopar that I know of that was vertical was my 58 Fury 350 engine with 2 four barrels because there was no room to place it horizontally. Probably other multiple carb engines had to place them vertical.
Horizontal is fine, seems good to keep terminals horizontal too. That keeps them in oil. A leak at tower is sometimes a loose screw, in tower terminal.
