Any way to adapt for use with a 6cyl? Or does anyone know of another aftermarket tach I can stuff in my cluster?

Connects to coil (or HEI distributer w/ a tach connection), and does not have an internal option for 4/6/8 cylinders. Would have to be an external solution.

Look them up on the web and give Rick or Butch a call. They'll tell you what info you need to give them along with the tach and an estimate of the cost.
