My car came with the rallye pack gauges and I would like to know if there is a way to make it work with an HEI distributor? I bought the car from the original owners son and he put in HEI and said he couldn't get tack to work so he just left it as is. Can I make it work somehow?

thanks

Unless he fried the tach,
there is a provision on the hei cap
marked "tach." If you know which wire
coming from your tach going to the old coil hook-up,
it should work. I think it is a brown wire? Not sure.
