well, i just got back from marine boot camp and have some time and money to mod the stang a bit more. On the way is the 255lph and an ignition box and coil. I was looking at the MSD 6al and the Crane hi-6. They are almost identical except that the msd has analog circuitry and the crane is digital. what is the difference between the circuitry types? Pros and cons? And your reccomendation of boxes. I know that if i get the MSD box i will get the blaster 2 coil. But if i get the crane box, which coil should i go with?
