The Deve setup uses an obsolete trigger wheel and pickup coil for a MOPAR six cylinder ignition system that was only produced for a short time, to trigger a Delco ignition module. It would make a lot more sense to use the whole GM system adapted to a stovebolt housing. It only works on 12V negative ground, also.
