Stalls in Gear, Automatic- Restarts Good- Can Slam it into Gear! EEEK

Could use some old school help on my 76 Dodge Dart 318 Automatic. I've been trying to figure out why the engine stalls when I put it into gear (restarts immediately) and I've run out of ideas. There isn't anyone around that knows how to work on this thing that I can find, dealership, aftermarket garages other than me. Here's what I have done up until now and not only to correct this problem.
Compression good, new spark plugs, wire set, rotor, distributor cap, ignition coil, ignition module, set pick up gap because reluctor was touching pick up, ballast resistor, pcv, fuel electric pump, 7 psi pressure checked, new fuel filter, rebuilt carb, double checked float level and for holes, idles mint, starts mint, sweet spot with timing light, no vacuum leaks other than small one at egr which aprears that it was designed that way but replaced intake manifold gaskets, cleaned grounds, fluid levels up, . If I reve rpms high I can slam into gear and take off. Coming to a stop stalls but restarts. Doesn't seem to shudder just stalls. I can turn idle screw all that way up no difference. Cleaned firewall electrical connector real good. Doesn't have a lock up torque converter and a transmission guy said he didn't think that would be the problem unless bad shutter coming to stop. Good ground to distributor. Vacuum is good on my gauge can't remember the reading right now but its in the green kinda thing on the gauge (20 inches).
Any help would be much appreciated.
