Sinitro, good info. My take on this is to use a matched coil/ballast combo preferably an E coil & maybe one (FBO?) that I believe needs no ballast to get a hot of spark with however much decreased longevity your comfortable w (more power=less life) and a $15 parts house 4 pin ECU to switch it tho the ECU is just a switch it can only switch so much current on/off just like the points it replaced
