i mounted mine on the side of my back seat wood. my back seats face each other and the side that is by the engine worked out just fine.

they are supposed to be waterproof i hope. i have had mine mounted there for a year and no problems yet

mine is mounted to a plate on my head.

mine is on the front bulkhead

There are no issues with running the wires for longer distances, by mounting it in the front?

Marc, do you have a picture?  How did you attach the box to the wood?  Did you use the rubber mounts?

i used one size larger wire

I am doing the same setup 6al, promaster coil, Magnetic pickup, and have been wondering the same thing. I was thinking of making a clear plexi-glass waterproof box atatched to the transom (where my exhaust used to go through) but I am concerned about the longer coil wire. My first choice would be as close to the distributer as I can get, but I am worried about the heat/water exposure, not to mention the engine vibration . Then comes the other issue, the new dual carb setup.......what heat range spark plugs!!!
Brad do you have a chevy or olds?.... 

So no issues with vibration by mounting it without the rubber feet?

You can run a long wire for the the mag pickup, and having long primary wires, as long as they are a good gauge, is also OK. The shorter the coil wire, the better. However - it's better to run a 4 foot long msd 8.5 (50ohm/foot) than a one foot Mallory Sidewinder (600 Ohm foot) or heven forbid even an inch of those pep boys / autozone factory replacement cables (10,000 ohms / foot)

Here is mine. It is mounted on the left side of the back of the seat. Tucked in there pretty good. I might box it in with clear plastic.
