Hi kikkegek,
I don't have a diagram for the Calif emissions feedback carb wiring, but I'm pretty sure that white wire off the distributor runs to a control module mounted under the dash (behind the glovebox).
Since you removed all the emissions stuff, I think you can safely unplug that white wire from your HEI and replace it with the wire going to your tach. Try that instead of tapping into that wire as I had mentioned earlier. Although unlikely, there might be something in the control module at the other end of that wire that's keeping the tach from getting a good signal.
