Under Drive Pully's

[wvstang5.0ho]

Well Im getting ready to put a new water pump on the Stang this week and thought it would be a good time to install the under drive pully's. And I was wondering if when installed do you still use the same belt ? Also any tips on the installation of them ?

thanks Brandon

The pulley kit says what belt most of the time if not, when i put my underdrive crank pulley on the belt was i believe 4 inches shorter. If that helps.

Damn Link !!!!! on the belt size. No one seems to know the exact size, so I had to thread a rope around my pulleys and take it to the auto parts store for sizing.

Well the one that was on it seemed to work fine, I measured with rope before and after and was the same, looks like to me on mine the only thing different as far as the pulley's were they reversed the water pump & Crank pulley size and the alt pulley was the same size as original. So any way got them on and WOW did I notice a gain in excelleration immediatly, I couldnt believe the difference. But thanks guys for all your help.
