For several years, I had the coil mounted vertically on the RH fender apron near the alternator. The coil wiring isn't long enough to reach that position, so I'm thinking of mounting the coil on the intake in front of the carburetor, like stock. Putting it there will look cleaner and the wires will reach. The instructions that came with the MSD coil are a little vague. They state that the coil is designed to use the factory mounting brackets but later it reads that mounting the coil vertically is recommended. All the factory coils were mounted horizontally, right? What could be different about the MSD coil to warrant a different position? Who has actually had trouble with their coils by mounting them on the side? Yeah... I could just solder in longer wires to reach the fender apron, but I sorta like the idea of cleaning up the area to look less cluttered. Opinions?

It didn't say it was mandatory, just recommended. The factory coils were oil filled too, so what the heck?

Any oil-filled coil has a tiny air pocket (to allow for heat expansion.) When mounted on their side, the air pocket can expose some of the windings, causing impoper cooling and damaging the coil. Many coils are mounted sideways (including mine)and are fine. But upright is ideal. Epoxy coils do not have this issue. 1969 Dodge Coronet Super Bee 383 A4 1970 Plymouth Road Runner 440 FC7 (sold)

topside Too Many Posts Joined: Jan 2003 Posts: 20,813 A collage of whims	Over the last 40 years I've mounted coils vertically & horizontally, and the only one I can recall leaking was on a SB '57 Chevy I'd bought and it was vertical. The MSD B2 coil on my Roadrunner has been horizontal in the stock location since 1988.

They have a black anti-vibration, epoxy filled coil that can be mounted in any position. peel the label off and it looks stock
