Hi Doug,

It is actually a '66 K20 with a power pak 283 in it. it should have the 12vdc wire connected to the start post of the starter to provide 12v for easier starting and the resistor lead from the ignition switch to the run post of the starter to provide lower volt.age to the coil while running.

I am hoping to avoid a visible ballast resistor in favor of an almost invisible length of resistor wire, but cant seem to find it. i was just going through a Blue Streak ignition catalog from 1972 and don't even see it listed.....

Thanks
