As i was looking through mu Summit Catalog for which ignition to buy i say the Jacobs Off-Road ignition "system" that includes the computer, coil, and an angle sensor.. Seems like it is just like a MSD, don't know the exact specs but i suppose it to be like a MSD, lots of sparks low rpm for a certain crank rotation. Also, will it work with a ford, i know ford uses a TFI coil, the jacobs seems to use it's own. i'm going to email jacobs and see what information i can get from them on specs and if the system works with a ford. I was wondering before i make my final decision, what does everyone recomend for an igniition?
