    Rated 5 out of 5 by from made big difference Have not driven many miles since installation along with MSD distributor and coil but made an immediate difference. For me worth the price. Nice looking addition to the engine compartment.

    Rated 4 out of 5 by from Easy Install The MSD installed with ease. I installed on a Ford FE390 in a 61 Starliner, trying to improve it's road manners and warm starting issues. I also got some very good help from JEG's tech support dealing with a Mallory 9000 series distributor.

    Rated 3 out of 5 by from I have had problems This is the 3rd MSD that I have purchased for my 1981 Jeep CJ-7, and less than 10,000 miles. The first was an offroad model and when I contacted the MSD manufacturers in El Paso, Texas, they said it could not be repaired even though it barely had 1000 miles on it. The 2nd was a MSD 6AL that had 7 or 8,000 miles on it. It would just quit and then you could let the vehicle sit for a while and cool off and then it would start again and then run for a while and quit. I bought a new coil thinking this might be the problem, same thing. I just recently bought another MSD 6 because I use my jeep to plow a little snow in our yard and I also pull my boat sometimes. Luckily I have a K&D tools ignition bypass that has its own coil and I was always able to move my jeep if I got stranded . I am running a 401HP engine with a Turbo 400 Trans full length header, Edelbrock performer intake and cam. It runs great, just wish that I could depend on the MSD to not quit on me at the most inopportune time.It has a fiberglass body but I made sure that the MSD unit was grounded to the engine and rubber shock mounted. I ran MSD in my 1966 426 Hemi charger with no problems, but not much luck with my jeep. I cannot recommend this unit very highly. I did not contact MSD Manufactures on this latest failure, because they pretty much blew me off on the last one. Also I habe been running a MSD 6 on my 1990 supercharged Mustang and I did have one failure with it years ago and had to replace it with another. The 2nd one does not have many miles on it and is working fine.

    Rated 1 out of 5 by from MSD 6A Sucks This has been my second MSD 6, The latest one I used on my 1964 Ford Thunderbird, It was hocked up for about a year before it started making my car cut out while running. I thought maybe its the coil. Luckily the MSD took a total dump while in my garage so I did not have to tow the car. After unhocking the MSD and just running my electronic ignition the car now starts fine and runs fine. I do believe the multiple spark ignitions are a gimmick. My car runs better with the electronic ignition distributor but no better with the MSD also hooked up. All I need is a good spark and that is what I currently have. No more fancy ignition boxes for me. What a waste of time and money.

    I have a 6A. New tach does not work properly. Do I need a MSD tach adapter or would switching to a digital 6AL take care of it?

    Asked by: Domo
    YOu will need to use the gray tach wire output with most aftermarket tachometers. SOme of the in dash factory tachometers will need a tach adapter.

    Is there a rev limiter that will work with a Digital 6A to save me having to buy a 6AL? Thanks

    Asked by: RufusB
    No, you will need to upgrade to use a rev limiter on your vehicle.
