electronic ignition and tachometer

[kinleydog]

I have a '74 Javelin with a 360. I'm interested in converting to the MSD Ignition system and coil. I also want to replace the standard instrument gauge with the tic-toc-tach instruments. Will the tachometer still work if I replace the ignition, coil and distributor? Is the tic-toc-tach a mechanical or electrical tachometer?

The AMC tic-toc is an electrical connection.

Many thanks donsjave for the info. This at least takes one impediment out of the equation.
