with my 350 - mild cam - I run the in gear idle at about 700-800 RPM. That makes the 'park' idle at around 1100 rpm depending on temp of motor.

I'm not sure when you should feel it kick in - depends on your TC. I feel mine 'thunk' into gear as soon as I drop it into gear - it immediately starts to pull the car in the correct direction - at idle - in third, if given a long runway my car will pick up quite a bit of speed - say to 20mph or so - but I have really tall gears.

Get two people - start it up - have one person under hood with a screwdriver - other puts car into gear and holds break - don't run over your friend - adjust the idle until it's smooth. Drop back into park and check again - make sure it's not too high (above 1200? - just a guess).

Of course there could be timing issues as well that would affect the idling.
