In the 80's Only the 305 and 4.3 had the ESC system. It is possible that is the case even with the newer trucks.

Also, if the knock sensor was disconnected and a fault was detected, it would revert to a 'safe' timing curve, or fixed timing. I doubt thats what caused the overheating.

The water pump type used is dependent on if its turned by a v-belt or serpentine belt. serpentine belt would spin opposite the engine rotation while a v-belt would spin the same direction.
