WATER PUMP DIFFERENCE

HOW CAN YOU TELL A SHORT WATER PUMP FROM A LONG WATER PUMP?     WHERE IS THE DIFFERENCE?               THE ENGINE IS A 305.

The biggest difference it the short one is right up against the timing chain cover while the long one there is a good amount of clearance, around an inch.

The easiest way for me to tell is that the long water pump has provisions on one side for the power steering pump mounting and on the other side a provision for the lower alternator bracket.  A short pump has neither.

No 73-87(91) trucks ever used a short water pump, and no 305 ever had one either from the factory due to the fact that all used the new bracket system.

thanks for your responce, but it just hectic every time i ask for something on my engine salesmen always ask this question...... dam-mm it they both seemed identical to me. I was on the verge of installing an electric water pump. if i do this what are the ups and downs on this conversion?
