No spark when with the key on run or on start while cranking?I believe in 1966 they probably ran the wire for the ignition coil from the R terminal of the starter solenoid but since this has been converted over to HEI, there should just be the one connection marked B+ at the distributor cap if this is in fact the coil in cap HEI, then that could either be coming straight from the battery positive post or like some people including myself like to run it off the fuse box from a spot that is hot only while the key is on start and run.
