mag 44
if you are running msd components the tach can be picked up off your timing ciontrol, if you do not have that component get a msd tach adapter for a mag 44. it wires to the coil P/N 8132. msd also makes a shift control that will work with a mag 44 P/N 7559 they both work well with the mag.. make sure you do not overload the tach port with a lot of items, shift control, data recorder, tach...
