    Mine has been mounted right here on the left front fender apron for ~130,000 miles. Car is a daily driver and sits outside year round.

    Maybe Radio Shack still sells those nice brushed aluminum hobby boxes in various sizes that would look much better than a bulky plastic battery box. I built the electrical portions of bucket trucks and digger derricks for Altec Industries at one time and some of the stuff we built was in housings such as this type.

    Put the cover on and everything disappears :dance:

    Do these boxes give off any heat?

    They don't realty give off any heat but if I'm not mistaken the msd instructions say it souls be mounted away from heat and moisture.

    B.S. Where'd you get that info ? Mine's good to the motor's rev limit of 7 grand. I've seen a Duraspark throw a spark three feet across a 400.

    OK....If....You want clean? This is where Im going. 302ford380x285.jpg If one considers the cost of all the MSD components, this set up is cost effective. The stats on spark duration and amps are way better. IMHO. This is one step below a crank trigger. "We dont need no stinking Rev Limiter"!

    I run a 6AL just for the rev limiter.Being a stick and the fact i drive it hard it's nice insurance.Car runs 12.80s with or with out a MSD box makes no difference on a mild engine.A MSD distributor uses a Duraspark magnetic pick up, the only advantage is tighter tolerances makes a more accurate distributor.
    A good friend of mine has a 69 Nova 427 bracket car runs very consistant 10.70's with a MSD 6al and distributor.One big event the car had ignition problems and we had limited time to fix,he pulls out a HEI dist from his trailer with welded weights in it ,stabs it in the Nova and the car runs the same 10.70's.
    Now with that said i'm not saying the stuff is junk just not always needed

    WOW!!!:thumbs2:

    I am sure your motor will turn 7,000 rpm, with the duraspark box. But, what you are failing to realize is, the voltage of the Duraspark box, dropping off after 5,000 rpm, where the MSD, does not. I stand behind my previous statement 100%. So, what we have here is, a case where you haven't done your homework. So, I am not B.S.

    That's your opinion. Mine doesn't miss a beat above 5000. Try it. As long as the fire is lit, when it needs to be lit, voltage doesn't matter.

    I'm sure you get fire above 5,000 rpm, but it is not what it could be with a superior ignition system, such as MSD.
