Looking for info on the 440 4BBL Torque Converters

I agree with Rusty. I just put a 5.9 Magnum in my 66 Barracuda and called PTC (Performance Torque Converters) out of Muscle Schoals, Alabama for a converter. I am amazed at how well their converter acts. Drive normal, it acts normal, pedal to the metal and it flashes to just over 3000.

Kenny, the owner, is a Mopar guy. Give them a call and see if Kenny is around to talk to. I spoke to Tommy, the sales guy, a couple of times and Kenny once. I wouldn't hesitate to buy from them again.
I filled out their online spec sheet, but i'm not looking to spend over $250 on a TC and I doubt theirs will be in that range.
