FBO or MSD what do you use?

Just a good quailty cap and rotor should do fine. The dist itself is not going to help rotor burning. Jacobs makes a box called milage master (I think). We installed one on my sons 72 360 swinger. It helped start up, mpg and power. These computer ignition boxes must be full of PFM to do what they do. (pure freaking magic) lol ray
