Ok so I like my carbs and I thought hmm wouldn't it be neat if I could hook up a crankfire system. I mean really I've got the msd installed, so whats next? I need a magnet set on the flywheel a magnetic pickup on the fan housing and a coil pack right? Wont the MSD handle the coil switching? I dont want to go full blown Megasquirt or anything like that just want crankfire with the carbs. I have a buddy who was going to design one for me but he still has a couple of tug boat diesels ahead of me and it looks like it may be awhile.

Thoughts? Can of Worms?

the standard MSD box has no logic, all it does is get a signal to fire and it gives juice to a coil, for crankfire (wasted spark I'm guessing you want), the MSD will not be able to switch back and forth, you'll also need a device to control spark advance....for a pure race only motor, you could just setup max advance and it'll work if you ran two MSD boxes

the cheapest method I've seen is using the ignition from a pontic sunbird, no tuning, you are stuck with the factory advance curve, but it works (Clay did it years ago), next would be EDIS or find another 4 cylinder car that you can salvage parts from.

if you want to spend real money, Electromotive is the next step...
