Re: can u mount an MSD upside down?
Highly encouraged not to if your mounting it in the engine compartment and will be washing the car or driving in rain. The circuit board for the box is in the top ( in reference to the label) if it gets even the littlest bit of water in there your done. MSD does not recommend it. Not like it's going to be ok if you get water in it while it's right side up, but your chances are better. If it's in the glove box or in the car, go for it.
