it broke the belt, i got a new on and put it on, all seemed well, an hour later i went to pick up my daughter and got about 3mi. down the highway around 60-65 and heard what sounded to me like spun bearings(loud squeling but no metal on metal type crash) then it stalled.I won't know the extent of the damage until i get it out and apart. I promise i'll report exactly what i find. In the mean time i've got to either get the 320 engine/block to work or i'll have to rebuild mine(if it's salvageable).
