From the looks of it seems as though the I had the crank snap on me..... half throttle let out of it in traffic and got about 1/2 down on the throttle and the truck just died. Opened the hood to see the blower belt missing and pulled on it only to hear something moving.....daylight showed the crank pulley/lower blower pully and a piece of teh crank all connected along with the empty hole in the block.....pretty pissed considering it was under no stress what so ever.
