As far as fuel goes, I believe VP recommended C12 race gas @ 113 octane when I spoke with them, but to be sure I would have to dig thru my notes. MSD's preferred recommendations are #8201 pro power,which appears to be very high output short duration use, oil filled coil. Also, the 2 HVC square box style coils #8251 &#8261, one of these is made for longer duration use. My car is strictly a drag car with no street use. I am leaning towards using one of these 3 coils, just not sure which is best suited. It will be used with 7al2 ignition box. Thanks, Bill
