I built a crank trigger some years ago for a 440 but in the end I had to buy an expensive aftermarket "brain" to be able to set the parameters. It works very good and the ignition was as good as I expected, if not better.
I don't remember where I found it or the manufacturer and I don't care because it was so expensive and I like to be cheap.
My question was if it would be possible to find something usable on a junk yard? Wheel and sensor you can buy anywhere, but the rest?
I'm not going EFI, I just want an excellent ignition that sparks exactly where it should be, I know how much better my crank trigged 440 runs!
To get a timing point for all eight cylinders is very difficult via timing chain - cam/distributor gears - play in distributor and that tiny reluctor wheel. And upon that phasing. Ever experienced a scattering timing mark using the timing light? No more. Steady as a rock.
After hours googling and just getting "MSD Cranc Trigger" results I found something interesting.
I have just ordered a Megajolt Lite Jr:

and then a Ford Edis-8 module complete with coils on ebay for $75. A friend had a trigger wheel for $20 so all I have to buy now is the pickup.
I will get a fully programmable crank trigger ignition for less than $300 plus a little fabrication of mounts and weld the wheel to the crank pulley.
I will get fully adjustable timing curve, rev limit and also vacuum advance. Even data logging is possible. And if the day comes I can connect an EFI to it.
Maybe I have missed something but I don't see any advantages with MSD crank trigger system?
I really don't understand why I'm so alone on this path...
