Has anyone converted to a msd 6al or similar cdi box on their 84-86 302-351? Looks like a pretty straight forward swap other than neither of my manuals show me how to tell the difference between the duraspark II or III. Or where the ballist resistor is

 

Well i ordered an MSD 6AL box, Blaster 2 coil,wires,cap,rotor, And plugs. I will post my findings and any gains if any

 

Well It's all done. She starts right up and runs GOOD! I opened up my plus to 055" an jetted it up 8 percent rich. Improved takeoff power and crispness. Improved economy and no more raw fuel smell. Pics soon to follow. Shoot me a pm if you are considering this upgrade. It has been well worth the investment

 

Interested in the MSD install, photos would be great. I too have an '84 302 with rich running.

My plugs, wires etc are all new and it starts/stops fine but just has a
lot of unburnt fuel.

Am waiting for my rebuilt 2150 2 bbl to arrive and hopefully that will cure
the rich mixture.

 

I sent you a pm, but i'm not sure if it went through. Your replacemnet wires will cripple this system and will most likely need to be upgraded. I was also instructed to use the MSD cap and rotor due to the oversized termnals and special coating. Sales pitch or not its cheap insurance when converting your ignition to a CDI unit

 

Ok here are the few pics i have of the install. Wire are still long and need to be wrapped and loomed. I will get to that as soon as i find some more wire loom. I seem to have bought it all in my area
