Continental converters in CA has 11" Torque converters for AMC Borg Warner Transmissions. I have a pretty stout combo for my 343 and was wondering if a 11" 2500 stall converter would make the AMX faster?

Heres the combo:

68 343 Bored .030 with 70' 51cc dogleg heads. 1/2 head bolts, reed 272/276 torque master cam(491/501 lift 110 lobe sep), harland sharp rollers, titanium retainers, rollmaster timing chain set, 750 competition series AFB Carter, Edelbrock R4B intake/blocked heat risers, hooker headers with full mandrel bent 2.5" exuast to bumper. M12 390 trans with a BIG auxiliary cooler. 3.15 gears.

My thinking here is rather than go with tearing down the rear end and swapping low gears in the 11" 2500 stall would help the car accelerate quicker than with the stock converter and still keep the stock rear gears?? they are either 2.87's or 3.15's.

It will be a LOT easier to just slip on a converter and change gears in the future if I decide. Any input on this is great!
