How do I tell the difference between a long and a short water pump? I have a Chevy 350 V8, a crate motor the same size is going in very soon. How do I tell which one I have so that I can get the correct brackets, accessories, etc.?
till it truly is made formerly 1970 it incredibly is an prolonged pump. bypass to a various factors place. the fast pump suits tight against the timing cover. The long pump has approximately 3/4 inch between the bck of the pump and the timing cover.
Dude's lengths are incorrect.. The short pump is 5-5/8'' long and the long neck pump is 7'' long . That's with a V belt short block chevy....
The short water pump body measure about 3 1/8, while the long pump measures about 4 3/4. That's measured from where the pump bolts to the block to the outside part of the casting. Not including where the shaft is. If you're looking straight down over the motor and it has a short pump, then the front of the timing chain cover and the rear of the pump are almost on the same line. If it's a long water pump, then looking down there would be about a 7/8 space where you can stick your finger. But don't do that, you could hurt yourself. :-) Hope this helps.
Make it simple. Use the brackets and pump off your old engine. If you don't have one, go to a junk yard and buy all the front stuff with the pump off any 350 that looks clean to you.
