what stall torque converter do I need?

I am finishing up a 393W stroker. Trick Flow heads. Performer RPM. 10:1 compression. Hooker headers. Comp cams solid flat tappit cam . .584 lift and 237 degree @ .050 intake and 248 degree @ .050 exhaust. Rocker arm clearance .020 with will lessen the duration slightly. Holley 750. I am going to get an AO Dominator transmission with wide ratio gear. 1st gear 2.84. Non-lockup torque converter with a strong 1 piece shaft. I am guessing the engine will put out 450 horsepower. It is all going in a 1969 Cougar convertible that weighs 3600 lbs wet without me in it. I know I am probably leaving something out. Thanks in advance

I know what i forgot. Rear end 3.5 gear locker. Tire height 26". I can bump that up if needed now that I am going overdrive. Thanks.

Not trying to be a ****, (which is easy when I am one), anyway, but go to all the different torque converter websites. Most ALL of them have places on their sites where you type in your info, for converter suggestions, prices/availability, etc.
The more pertinent, EXACT info you have on your vehicle, the more EXACT/correct they can be on ideas for your combo.
Personally I highly recommend TCS. (located in Canada).
A bit spendy, but you get what you pay for.

Thanks Drag79. I asked TCI and they suggested I go with a 4000 rpm stall. I think that was out in left field. 99 percent of my driving is on the street and I live out in the country so alot of 55-70 mph. That is why I want an overdrive. But I am not looking at a lockup converter because I am told that the two piece input shaft is a major weak link in a higher horsepower situation. I was thinking between 2500 and 3000 stall.
