The tach wire has some nasty electrical transients on it with noise going up to hundreds of volts. Tach inputs suppress these transients but the wire itself can be a really good transmitter.

Would a shielded wire help with that? Using distributor ground and tach ground for the ends of the shield.

Interesting idea Clay, possibly would help. And you've known me long enough that I'm not bashing or discounting the idea but I gotta believe there's probably something basic going on here. Many of us use HEI hooked up tachs with decent stereo's and don't have this issue.
