If I was you I would be putting in a tight 265mm.
You need stall speed even with big cubes and a blower. Given its street use you want flash speed to be below peak torque by a decent margin, but due to the way the truck has been built your torque curve is going to look like a shelf... so if you stall 3k-3200 wide open you wont wish for any more. By the way its going to take a really tight converter to only stall 3000-3200 - DON'T ASK FOR A 3000. Ask for a 2600ish.

I got a 2800 rpm 310mm torque converter from Summit. Hughes brand. I am hoping that their guess of 2800 RPM is as accurate as Circle D estimate of 1600 RPM. When I stomped on the gas with the Circle D, my tach went to 1800. I doubt it, though. Circle D could probably be more accurate with their estimate because of the similarity of my torque and a diesel's torque. I think Hughes' guess is a lighter vehicle and less torque. I will find out soon, I hope. I hope I don't get stuck in another work and weather cycle keeping me from getting it installed. And I hope my stall speed is well below 3000 rpm.
