Oem pulleys usually have the water pump pulley smaller than the crank pulley to obtain the proper ratio to keep the water pump spinning fast enough to move the water through the system. I know you changed these pulleys with the new motor and the old motor overheated with the old pulleys but I still don't know what kind of pulleys you had prior to the rebuilt motor. I would suggest that you use a smaller water pump pulley, about 6 inches or less in diameter, and a larger crank pulley, as close to 8 inches as you can find. At least you will then have optimized the water pump rotation speed.

sorry sir, meant to respond back to that. the pullys i had on it were stock and then i replaced them with the same diameter just aluminum and dual so i could run two belts. everyone else, i def appreciate all the feed back and would like you guys to give me your opinion on the fans that they recommend because i have the spare funds to just go electric and heard that it would cool a bit better. although i am open to clutch options if anyone can show me. would a pic of the motor and fan set up help at all?
