Need A Little help Please

I have a similar problem with my 72 Dart running a 382 stroker 360. I'm running W2 race ported heads, with a Comp Cams full roller with gross lift of .654 intake, .655 exhaust, duration at .050 269 intake, 276 exhaust. Lash is set at .022 int & exh. Running 5.13 gear in a D60. Holley 1050 Dom in Eddy Victor intake. MSD 7AL with crank trigger. 727TF built by LJ Transmissions in Colebrook, NH. Supposedly a 4400 rpm Turbo Action Converter, but have already determined the stall is no where near that. 60' times between 1.49 to 1.52, running a 14X32X15 tire. 1/8th mile ETs 6.70s at 104, best 1/4 ET 1.49 @ 124.
Having the converter loosened up to match the cam over the winter. Lou at LJ transmissions is going to go through the trans and install a transbrake for me, he's also going to go through the engine for me as this is a combo he developed some years ago and according to him with how my car is set up it has high 9s potential.
