904 band adjustment for a 408 stroker???

Thank you all for the input! I had my transmission thouroughly checked by my transmission guy, and he said It was in really good shape. I also had him install the Transgo TF-2 reprogrammer kit. I forgot to mention, the 2300 stall torque converter I was talking about I had completely rebuilt at cottman transmissions in woodbury heights, NJ. I told them what my plans were and they said now that they knew that, they would "install the necessary parts for that application"...Im guessing that would extend the life of it..? I am also installing an inline trans cooler also, but should I tap it in before or after the fluid flow direction going through the radiator??
Thanks,
