Coil position

Is it true that a coil should not be mounted vertically with the wires on top?
Seems to me someone told me that one time (something about an air bubble)?????

The only thing that i know of that would make any difference is if it's oil filled or gel filled. JMO And IIRC this only matters if you are mounting it on it's side. JMO

The Chevy's were on a little slant. that's what the guy told me that there could be an air bubble that would float to the top of the oil and then bad connection????

He is full of hot air. Only problems that arise from coil mounting is laying an oil filled coil on its side, the air bubble will cause the windings to overheat on the upper side of the windings. An oil filled coil has to be mounted vertically(or close to it) to keep the windings fully covered in oil for cooling.

Ford v8s used to have them on their sides on the intake....Were they not oil filled....or was that a problem with them?

It is crap, you can mount it any way you want. If it is oil filled it is full so position does not matter. I can remenber seeing just about every orientation of factory mounted coils with the exception of upside down.

I think you should mount it with the coil wire pointing down so the electricity will fall out faster and your car will run better

You can't do that...all the sparks will drain out overnight

I couldn't resist....

I thought that if you made sure the points where closed they would hold the sparks in! I hadn't thought about the resist

Laying the coil down didn't seem to bother Ma:

Then you consider the old pre '49 Ford coils mounted on the distributor, or might want to look at the HEI caps. In other words, what is up or down. Those fat old Mallory coils, the ones with the resistor around the secondary cover, I mounted mine on the firewall after I went to a 'Y' block in my '53 - and I never lost any sparks, even with my dual point distributor point wide open

If you're not convinced, you can switch to an "E-core" type coil. It doesn't have an oil in the first place, so it certainly doesn't care how it's oriented.
