rumor had it that you could use the stock belt but that is not true, So my belt is not fitting with my supercharger, i do have a aftermarket water pump pulley which is much larger then stock and all the other pulleys are stock size with a 3.33 vortech pully. The water pump is the same size as the aftermarket underdrive pulleys except i left the stock harmonic balancer on there, anyone have any idea what size it could be? it looks like its off about 10 inches

My stock belt is 102 inches, i dont have 80$ to risk on belt size, what the size of belts are from N/A to supercharged.

you can return them if they dont fit. I had to go back and forth when i went 8 rib and different pulley sizes.

i didnt think you could fit the underdrive water pump pulley with the stock crank. they must be super close

With a 3.33 pulley, a 108" belt will fit. A 108" belt will fit from a 3.12 to a 3.6 pulley. I use a 107.5" on my 2.87, but a 107.38" would fit good too.

windsor blocks are way better than romeo blocks its just your water pump is diff than the romeo's. you can swap out your entire water pump for a better one for fairly cheap. then you can use a romeo pulley.
