    My t-case is dropped so my stock distributor is so close to the firewall. Anyone running one of those smaller diameter MSD distrubutors? If so which setup are you using and how do you like it?

    Although I haven't turned the key on it yet, I'm going with the small diameter MSD Pro-Billet distributor for the clearance with my fuel-injection manifold. I've run many other MSD distributors in the past, and always had good luck with them.

    Hard to go wrong with MSD products, IMO. You'll hear some people questioning the boxes here, but I've also run those for many miles/years with success. Using a 6-Offroad for this buildup.

    My mechanic suggested I go with the Pro Billet (the small distributor) and the 6A or 6AL box... I'll probably go with the 6AL to get the revlimiter.

    As most people will tell you.....don't expect a HP gain. There won't be one. But you WILL notice a crisper throttle response, smoother idle quality, and easier starts.

    It seems like one of those things that just make the motor "feel" nicer, but can't really be measured quantitatively....I'm sure that makes spending the $500 or so a little tougher too!!!

    I don't have MSD on my 4x4 yet, but I do have a pro billet distributor &amp; 6AL box on my 2wd truck and they work great. Another thing I like about it is the mechanical advance, don't have to worry about vacuum.

    Sinch,

    As the name implies, it prevents you from getting too excited and over-revving your engine. There are plug-in modules that allow you to select the maximum RPM you ever want to go, and the ignition will start removing spark from the cylinders to keep you from revving past that point.

    I would imagine situations in sand or mud, where you might get the tires spinning and forget what RPMs you were turning....until your motor let go and sent hot oily pieces everywhere....[​IMG] Seriously, it's just cheap insurance, and really doesn't cost THAT much more than a standard MSD 6A box....seems like a sensible upgrade to me.
