It also depends on your transmission too. Do you have a manual or automatic? For a manual try 500 RPM in drive. For a manual try 750 in neutral. Before you adjust the set-screw on the Throttle body, see if your TPS sensor is out of adjustment.

The TPI instructions from FIS says 450rpm for 283-305.
400rpm for 327-400.
Above is for automatics when in drive.
For a manual car, 500rpm in neutral.
400rpm for 327-400.
