water pumps? How many different water pumps are there for the LS engines? Maybe we need a thread for them like the one for the oil pans. I know the truck pump is different than the Corvette but I am sure there must be others too. I am looking for the one that is the shortest and so far it seems to be the Corvette pump. The LS4 is shorter but I put it in a class of its own. Any suggestions?
I found the w/pump from an LS3 crate motor was the thinnest/shortest after measuring quite a few. I needed the thinnest one to gain as much room as possible for my '32 Ford street rod project, there is NO room in the engine compartment. I also had to get the LS3 balancer as well. I got lucky when I found someone putting the LS3 in his F-body and needed to use his original LS1 w/pump and balancer, they literally had zero miles on them.
I agree, a thread or a sticky about various water pumps with dimensions would be nice.

Yes, the Corvette pump is shorter than the truck/F body pumps and has no threads for a manual fan. I bought the Vette pump for looks and room. Now after reading Mike52s post it looks like I should have bought an LS3 pump!

Here is some good info on the subject http://www.nookandtranny.com/Info_LSx.html
Rick brings up a good point about the t-stats too, the Gen III and Gen IV are different.
txcar, I'll get you some measurements tomorrow from the F-body pump and the LS3 pump. I assume you are more interested in the engine mounting flange to the outer most point on the pulley.

What are the differences in the thermostats? The LS1 and truck have the thermostat built into the inlet housing.
I'm running an F body pump, aftermarket swivel thermostat housing and the separate LS2 thermostat. No problems.

It should also be noted, there is a LS2/3 style pump out there that has the inlet on the RIGHT side of the pulley - I have one. I'll post the picture - someone can feel free to steal it as who knows how long I'll have that pic on my photobucket site. Yes, its for sale if someone needs that - I had to get a Corvette LS2 pump as I needed the outlet on the left side. I'll take $175 shipped for it, its brand new, never been used,(was on a crate motor).
Here's a picture of the differance from a ebay company
What changes had to be made on yours?
[QUOTE=Rick Speed;13104971]You kinda got lucky... as I just found out I bought the opposite set up and there is some modifications that needed to be done to make it work.

You can use the Vette pump w/ LS1 accesories (what I did) by simply pulling out the Vette pully about 3/8" as I read about on here.
I had to weld on something on the pulley to attach the puller to but then cut / ground and painted. I also put a small tack weld inside the pulley bore after this. Can't tell it's anything but stock now.

Do you know what the application is for this pump with the upper connection on the other side of the pulley? I noticed a photo in the latest issue of Street Rodder where the upper hose connection is on the left (drivers) side of the engine. I am collecting information about various pumps for different applications and I haven't seen this one before.

Thanks for the replies. The photos that I have seen of the E-rod engine show the older pump with the top connection to the passenger side of the engine. I will do some more research on this and see what I find out.

I want to revive this thread, as I am really struggling to find a part number or application for this water pump:
Everyone refers to it as "an LS3 water pump" and several people have said that they come on LS3 crate engines. Someone above says it is the 2009 Corvette water pump but I haven't been able to find a definitive picture of this application. It's important to me that it is exactly like this - outlet on the driver side of the pulley.
Anyone know for sure the GM part number?
Thanks in advance!
