    Allrighty. I've decided it's time for an ignition.. I'm tired of having the engine almost not turn over in the morning when it's 20 degrees out. The question is, what ignition should I get? I was thinking the MSD 6-off road.. along with the over-rev controler and some kinda distributor.. unsure of what kind though. I could really use some help here.

    I like the MSD series of Electronic Ignition compenents. The MSD-6 offroad is great. it has some of the feature durablity found in the MSD 7 for racing. I would look into getting the blaster coil as well, its almost bomb proof. When you install the unit put it up high and dry and mount it on the vibration dampner bolts they have or make one out of a sheet vulcanized rubber matting( heat tolerant). Jacobs also has a nice set-up with these features too, its just too pricey.

    I'd recomend MSD like you mentioned. Have had real good luck with them in the past and plan to use them in the future. They have excellent tec support & help you out in any way they can. Had an MSD 6 Offraod box in my last truck and it did wonders. Improved the cold starts and throttle response drasticly, plan to put one in the blazer as soon as funds allow. Haven't personally used Jacobs products, but have heard less than raving reviews. Stick with MSD and you'll be one happy customer. - Jay

    I used to have a MSD and it was great. My stock distributor fried it though, but I plan for another one in the future when I'm a lot less broke.

    Make sure you use regular old fashioned copper plugs. All those fancy Splitfire/Bosche/platinum/high temp/multi spark/multi prong/etc plugs don't jive with the aftermarket ignition boxes because they were designed to use regular plugs.
    Look into the MSD distributors, they are pretty expensive, but I've heard great reviews from people who use them.
    All I've got so far is the MSD GM TBI coil and a set of 8.5mm Super Conductor wires, and they are high quality stuff. I'm going to slowly build the whole system up.
    Hope this helps.
