Variable hydraulic lifters for 440 engine

Giving the engine a little rev to 1000-1200 makes the tires rotate a bit but after stop turning again and just creep a little every now and then.
I set the idle rpm to 800 rpm, which still keeps the tires stationairy.

I also seems temperature sensitive as well, if the car has been off for 10 minutes and i start again it will not idle as good, throwing the tranny in Neutral will rotate the tires.
After just letting it get back to temperature and not changing anything it idles better and the tires remain stationairy in neutral.

I am quite sure now that either the torque converter has a problem or is the wrong type.

Edit: Giving all that a thought here...
As the torque converter likely drags on the engine too much in Park/Neutral already, this makes me have to increase the idle mixture screws more than i should compared to a "better suitable converter".
This obviously makes it to run rich and idle and cruising speeds.
If a proper 3000 stall TC does not apply any torque transfer during idle and when in Drive i should barely see any rpm drop when going in gear, the mixture would stay near enough the same and does not require to be enriched as it is now due to the load that is applied to it.

That's where i am at now, but please correct me if i am wrong.
