I sent this question to dynamic converters but they dont answer. Maybe you knwo the specs and can answer it? I jsut want some more punch off the line but dont want to change rear gear.

Hello, will the 11” street converter fit mopar 383 combo with 9.6:1 CR, 3.23 rear end, 727 tranny, lunati 60302 hydraulic cam (214/220 @ 0.050, 140 cranking psi, 17in vac at idle/neutral), stock intake, manifolds, ignition and heads. Car will be street driven, total OEM resto. For the time being I have the mopar 10 ¾ histall converter but it brake-stalls @2000 rpm and the car is very lazy off the line. I also suspect it makes a big slippage at highway speeds (400 rpms higher than calculated using wheel dia and rear end ratio).

Will the mopar 10” flexpalte (small one) fit your 11” street converters?
