is anyone running 8 coils on a bbc like the ls motors? is there any advantage of running 8 coils for spark instead of one coil?

vrooom3440 Oct 19th, 10, 2:27 PM It can be done... just need the right crank and cam position sensors and EFI controller. The advantages are pretty much the same as they are for any engine... reduced duty cycle for the coil(s) leads to less heat, elimination of the distributor, more accurate ignition timing, potential to individually adjust ignition timing on each cylinder. If you get really advanced you could run ion sensing on each cylinder and really optimize ignition timing for each cylinder... but I am unaware of any commercial EFI controllers which can do this yet.

It would emulate a seven pin HEI module and therefore would work with most any EFI ecu ? I dont have one done yet, I have two other electronics projects to finish first but this is on my list.
