Water Pump

Hello,
Still building my LS7 440 engine seen in my sig. I will be using all my F-body pulley accessories set up and I am now looking for a water pump. If i buy pump "19180610" will that line up correctly with my belt?

For some reason I am thinking I have to but the stock LS1 F-body pump so it all lines up.

Thank You!

That pump is spaced for corvette accessories. The 98-02 f body accessories, crank pulley is about 3/4" farther out. You'll need the f body pump.

Thank you for the reply. Can the LS1 water pump work with an LS7 block? Hope it flows enough for this motor and can handle the RPMs.

Not sure if there's much of a difference in water pumps. Same pump used on 4.8 to 6.2 trucks. Lots of big cubic inch strokers using stock pumps.

I don't know specifically the ls1 but I have a LS6 in a 04 CTS-V that I replaced the water pump from an 09 LS-7 with no material changes. I have converted the plumbing for the heater lines but that I know has no bearing on your questions.
