Borg Warner Trans Question

Maybe someone out here will know this. I've got a 69 Javelin, 343, Borg Warner 11B trans. Are there any companies out there that make aftermarket torque converters for these, or any companies that can modify an original? I'd like to have a higher stall speed converter (stock is just too damn low in my opinion).

Thanks in advance.

The B-W auto is generally considered undesirable for performance use. Do some looking, there was a lot of AMC's equipped with a 727 Torqueflite that will accept any standard 727 parts, from torque converters to shift kits to stronger gears, etc. etc..

Trust me, I thought of that. Problem is that bellhousings/bot patterns changed in 72 when they went to the 727 transmissions. Cranks (from what I hear) are different as well.

The BW trans works fine, and was rebuilt less than 5000 miles ago (before I bought the car). I don't have any complaints about it other than wishing the stall speed was a bit higher.

Should have bought a car with a manual trans, I guess.... Those are more fun to drive anyways...

News to me, I am pretty sure bolt patterns are the same all years....

OK, did more research. You're partly right. '72 still had the same bolt pattern, you have to machine the crank for an adapter to use the torqueflite.
