I don't know what a 7,4 I is or that type of supercharger, but I do know a bit about engines and wide belts, from OH-13 helicopters, to sb chevy superchargers, and my Harley with open belt drive. Normally a notched drive belt needs no tensioner, just the right size, it should not just slip on, it should be tight enough to have to be installed pushing or tapping with a flat board a little at a time top then bottom. If tension were a problem it would wear the belt down quickly the cause it to start slipping. If it is "throwing" your belt, it is most likely an alignment issue requiring shimming of your sprocket, with no retaining plates and your belt on turn your engine over without starting it, If your belt starts "walking" out from the sprocket, add shims or remove shims until the belt remains exactly on the sprocket where you placed it (a marks a lot pen helps). If you are not noticing the front of the belt wearing down, you are way out of alignment causing it to jump rather than break.
