Default DD Converter selection help from Australia

So I've got a 3600lb L76 with full bolt ons, a 3.9 rear and a 4L65E - stock cam and heads (for the next 6 months) will then be a 21x/22x with 11.1 comp. I'm in Australia and theres nobody that can promise me a converter that will cut a 1.5 60ft and be able to DD.

I'm looking at a Yank or Circle D 4000rpm stall. Is this reasonable for a daily driver? I do about 30 miles a day mixed driving. I'm really unfamiliar with the torque converter companies that are Stateside so any feedback is appreciated!

Circle D, FTI and PTC are all great. 4k doesn't bother me at all cruising around. It doesn't flash to 4k every time you take off. more like 1800-2300 depending on gear and weight.

Circle D makes great converters. I run a Circle D 3200 stall in my daily driven Silverado with cam/headers/4.11 gears and it drives like a dream, stalls when I need it to. I wouldn't hesitate to run the 4000 stall either. Obviously I'm not cutting a 1.5 60ft because I don't make enough power, but I'd be willing to bet the Circle D can do what you need for both a daily and track duty. Also just put a Circle D in my girlfriends LS1 swapped Silverado with heads/cam/headers. I've also heard good things about PTC, but I don't have personal experience running their converters.

My 3800 converter in a 4000 lb car with an L77 and 6l80e and 3.45s drives fine. I actually wish the converter was looser. Like the dude above said, it doesn't slip to 3800 driving normally.

Just to update this I've managed to order the Circle D 3800-4000 stall. Will bump this up when it's fitted!
