    The motor is a 327/250hp 130k mi un rebuilt as far as i know and stock except Edelbrock carb and intake and HEI.
    the idle is all over the place it jumps between 600 and 1200 rpm in gear.Other than that it runs fine. The carb is about 8yrs old with 50k on it

    What could this be,Timing chain,carb or what?

    Vaccum leak? maybe? Try using a small propane torch unlit around any place Vaccum could leak from, If it is leaking the propane will pick the idle up,

    Could be the advance springs in the distributor too.
