I'm having some issues with belts at the moment, I have a Gatorback on order from the States, supposed to be pretty good as far as multi-v's go.
The overdrive kit you are talking about must be purchased with the water pump pulley and yes, the same belt is used.
Have a look at the distance between the water pump pulley and the back of the blower belt as it lies on the crank pulley, there is 8mm at best. This is why the water pump pulley must be changed. Also comes with 2 new idlers, one smooth, the other one ribbed due to their positioning.
It will give you another 2 psi at the manifold.
