MSD coil installation

I don't have the paperwork here but a ton more zap. I thought it was 50,000v I could be wrong. I was going to p/u the msd distributor but a race buddy told me about a better one with rubber wires coming with it. If anyone is interested let me know and I will put up the supplier. ir3333, all I know is my 340 is running so good now. My cam is a purple shaft that is 2 above stock and this extra zap seems to allow the cam to work sooner. Sounds funny but instead of waiting to hit 2,800 rpm for the cam to kick in it appears to engage sooner. Anyway, the blaster coil has me sold. The dragsters with rope sized wires, watch out. The zap from these coils can kill you.
