I too have an aftermarket tach in my 84, it uses the alternator pickup. I remember reading about how they work, it picks up a certain signal from the alternator. Can't remember exactly what, my guess is it won't work. You could temporarily hook it up and try it I suppose, see what happens.

if i remember correctly the stock tach reads off a magnetic pickup on the timing gear. 1 revolution on the gear reads one revolution on the tach sensor. the alternator style tach reads different and will not work.
maybe contact the tach manufacturer and see if there is a difference between the reading and how it will work switching from a 1G and a 3G alternator
