It's been several years since I messed with my cooling system when I installed a Stewart waterpump. I'm confused as to whether it's a short or long pump. It's installed on my Vortec crate using Camaro serpentine brackets. I remember when I ordered it I got a Corvette pump with CCW rotation. How do I determine whether it's short or long?

Do some measuring & compare to this: http://www.dalesplace.com/htm/information/water_pumps.htm And then post your results. I need a pump for my serpentine system too!

Upon visual inspection next to another El Camino with a truck serpentine system rather than a Camaro , I can positively state I have a short water pump.
