setting up mgb with camaro 3.4 stock motor changing pully sys and cam which direction of stock water pump thanks barry

 

If the pump is driven by the back of the belt it is a reverse rotation pump, CCW rotation. If it is driven by the front of the belt it rotates CW. Being that you are changing pulleys you will have to figure out how the pump is going to be driven. If using V belts, the back of the belt is not going to be able to drive the pump.
