    nice setup. I'd recommend it. My dad has the setup on his dirt track car. I did the install from start to finish. Everyone else looked at the wiring and said no way. Its really easy to setup if you just read the right set of instructions(there are different ones for different setups). Best feature has to be the rev limiter. Dad's car is set somewhere around 7300 or 7500 and you can't even tell its hitting the rev limiter, its the smoothest limiter I've ever heard.

    Thats about what I wanted to hear.

    Just how weatherproof is the 6AL box? Will it withstand daily driving with the elements? I was thinkin about mounting it in the cab behind the dash or in the glove box.

    Am also kickin around the timing controller as well.

    I'm not runnin any serious HP but once my drivetrain is set its on like donky kong and I'll build a mild 350

    I'd stick it under the dash. Thats where it is on my dad's car, but thats cause they aren't suppossed to have them in his race class ;) So I have no idea about weather proof. It seems to be very well sealed up. I'd still try and put it out of the way if I could. I wouldn't worry about spending the ching on the timing adjust setup. I think you may need a MSD distributor for that anyway. I have

    msd info

    i had a 6al with the rubber mounts and killed it in 6 months . i had it under the dash. i upgraded to the offroad box in excange of the difference and the warrenty on the 6al. the offroad is water and shock proff . you half to buy the off road rev box to go with it tho. all the conectors on the off road box ar the gm wether pack kind. other than that its great. it would burn oil of the plugs in my old 350 smoker. it used 1.5 quarts in 40 miles , and after the install i could get about 5k miles more from a set of plugs.

    MSD ROCKS BEST BANG FOR THE BUCK!!!!!!!!:saweet:

    I ran the MSD external coil setup for awhile. Worked well for me. I used the HEI dust cover, Blaster SS coil, and MSD coil wire.

    As for the 6al box. Don't let it get exposed to the elements if you don't have to. They will take some stuff but they are not weatherproof. Do not keep it under the dash. You need to keep it in a place where air can flow around it to help keep it cool. If you do put it under the dash get yourself a little computer fan or something to blow some air on it.

    If you buy the 6 Offroad box you MUST keep it cool. The heat will kill that box faster then it will kill a 6al box. I had the MSD 6 offroad box in my truck and it died once from being in the heat of the engine bay on the firewall.

    Some say yes, some say no. I am a yes man. My MSD made my truck with a carbed 350 run alot better. It gave me all the gains they hype up. Gas mileage, easier starts, more throttle response, etc. I really liked my MSD. I don't think it would help a fuel injected motor as much as a carbed motor though.

    It seems kind of hit and miss with whether it helps or not. It did help me. You could definilty tell the difference.

    Yeh the marine box is the 6M-2. I read they are not exactly suited for trucks because the spark burns longer to keep the plugs from fouling and they can actually mess up plugs in a truck. Also becuase marine applications constantly see high rpm -vs- street driving low-mild rpm range.

    I am thinkin about goin with the OffRoad box becuase its weather tight. Back home there is alot of water crossings on many of the trails I run which is why I need somethin waterproof.

    Any comments on the OffRoad CD box?
