Most likely the problem is a weak battery connection to the instrument panel area. The xtra current used by the HEI in your ignition circuit plus the current drawn by your directionals is causing a voltage drop in your battery feed harness. As a result your tach does not get enough voltage to work correctly.
Look for a bad/weak fusible link or a corroded fuse boxignition switch terminal. Regards, George

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
