Dumb water pump question

This is going to sound pretty stupid, because it is, but how can I tell if I have a short or tall water pump on my engine? I want to replace the one that is on there now but I don't have a clue.

Re: Dumb water pump question

What car, engine, year? Do you have one in place?, Short pump is just that, very little clearance between timing cover and back of pump, say early years to about 1968 or mid 68 or so, then the long water pump was on after that, Lots of space between back of pump and timing cover.

The short small block water pump is about 5-3/4" from the back of the pump to the pulley; the long pump about 7".

Re: Dumb water pump question

Thanks Dan. I'll take some measurements in the morning. Am I correct in thinking that if I change from short to tall or vice versa then my ps pump and alternator will not line up with the pump pulley?

Re: Dumb water pump question

You are correct. If you switch the waterpump length, you need to change ALL pulley's and ALL your accessory brackets. With a stock short water pump the alternater is on the driver's side. With a long water pump the alternater is on the passenger side.

Re: Dumb water pump question

And don't forget that Chevy made THREE, short, in-between and long!

In-between is for the 'Vette's if I remember right.

Please check Alan Groves site for more info if not mistaken.
