Mike,
Check with Theo Smit. He has created an electronic alternative to the
analog bits of the tach. You can either buy the board from him, or send
him your tach and he'll modify it. I've built several of these and
they've worked very well.
Here's a link to all the info you'll need:

Hope this helps,

Subject: tach tech
Hey gang:
I have an MSD distributor, but without the capacitor discharge box (I
may add
one in the future) . The tach in my tiger is reasonably accurate up to
about
2500 rpm but after that it's erratic and goes completely nuts above
3000.
I know the stock tach is only compatible with points or with Pertronix
unit,
but would prefer to stick with this distributor. Read the article on the
STOA
site about adding a capacitor and other mods, but am wondering if
anybody has
another resource or recommendations for getting the tach modified or
rebuilt
to work with electronic ignition.
Mo Ma says they can rebuild it to work with electronic ign. for about
$200,
which sounds pretty much like replacing the entire guts. Nisonger says
it
can't be done and recommends the Smiths unit for a 427 Cobra.
