I wanna switch from the CD box I now have to an MSD 6AL. Summit has a pretty good price on the box but what else do I need for the installation?

Thank you very much...

When I put mine on I also used the high vibration coil, 8.5mm wires and a points eliminator. I get about 15K volts at the plug at idle read with a SnapOn high voltage tester for spark plug voltages.

You should check jegs.Com, I just bought a 6a from them, they have the 6al for $35 less than summit. You also need the tach adapter. Also, you can get the rev limiting rotor for our distributor for around $20 at your FLAPS, & then get a 6a instead. 6a is $148 from Jegs. Pelican has a tech article on this subject & author included the part numbers for everything you need.

I just need to know what all I need...

I can buy the box from Summit with a 10 percent discount or get it from Jeg's. I just want to make sure that I have what I need when I swap it cause I'll be somewhere else....

mallory cdi is nicer...

digital vs analog, and a rotary switch for rev limiter vs a pill like MSD....

You need a high vibration coil and new higher-rated plug wires.

I also want to dump the points and install a pertronix. Do I need the 3 ohm or 1.5 ohm coil?

Will the Pertronix Flame Thrower 40,000 Volt Coil work?

allan you need a CDI specific coil. they are even less than 1 ohm resistance...

i tried a cdi with a blue coil, and it would have a flat spot. run great, and die at 4500 rpm, went to a 1.5 ohm coil and it died at 500, called mallory tech and they reccomended a super low impedance "e-coil" for a cdi setup. msd will most likely tell you the same...

pics of my setup are in my blog.....

Many people are running MSD with a bosch blue coil and no issues. The six I just bought was running a "Flame Thrower" 1.5ohm coil and it didn't run all that well. They are oil filled and should never be mounted upside down as this one was. Oil filled coils can have a bubble (try to shake them) and when upside down the bubble will rise to the top and potentially allow the exposed part of the coil to overheat.

I'd go with the MSD epoxy filled anti-vibration coil, that way you could mount it any way you like with no worries.

Go to Pelican Parts 914 parts page & go to the ignition parts where you'll see the MSD ignition stuff. In the listing is a link to a tech article on installing the MSD ignition & lists everything you need by part number.
