    Idle in neutral when cold = about 1000 rpm
    Idle in gear when cold = about 700 rpm
    Idle in gear when hot = about 800 rpm
    Idle in neutral when hot = about 1400 rpm

    What could be causing the overly high hot idle? Carb in chokeless. Engine is BBC w/procharger. Timing advance is about 8 deg initial.

    Read your plugs. It sounds like it maybe leaning out upon warmup. I don't know too much about pro-chargers, yet with forced induction there is a need to richen the system up I believe. Contact ProCharger for specific info is all I can recommend. It might be a simple jet change.
