did he put a msd box in it? if so you'll need a tach adapter from msd.

Could need to be calibrated. How high does it read?
I once had a tach read double the actual RPMs. I lived with it until one day the car wouldn't start. The resto coil was the culprit. A new coil and the car started...BUT - it also solved my tach problem. Must have been an internal short or break in the coil, I don't know. But the tach reads correctly now with the new coil, FWIW.
