Re: torque converter ?
If you plan on leaving your truck stock turbo forever I would use a stock converter and take comfort in the fact that your tranny should shift hard and operate properly for a long time.
If you are likely to race and upgrade to larger turbo and modify the motor I would compromise now and get a 2700-2800 stall, it will be a little big for your stock turbo but not overkill, and still work well when you upgrade the turbo. Just MAKE SURE it's not a shitty loose N/A converter and MAKE SURE it can handle the BIG BLOCK style TORQUE our engines put out. Otherwise you'll lose 5 tenths and a ton of MPH and your motor will sit at high RPM all the way down the track and you'll never feel it shift.
