  • o2 bung plug?

    Any idea what to use to plug the holes for the o2 sensor's? Need to plug them until I go EFI.
    Thanks

    I used O2 sensors I got from pick and pull. Just cut off the wires.

      Or... just get oxygen sensors and leave them in until they have a functional purpose. You will need them anyway and you have a pile of parts sitting there ready...

          Gasketed type (not tapered seat type) big thread spark-plugs also work.
          Cross-threaded is tighter than lock-tite

                      Only thing I see wrong with running new sensors in that hole while you run a carburetor, is if you run them longer than you expect and maybe your tune is not really all that great anyway, you might just foul up your new and expensive sensors.

                      I'm all for the old spark plug routine.
