General spacing applies for the water pumps as well. You can NOT
use any water pump on any LS based engine. Yes they will bolt up, but
spacing is very important, same as pulley size, ect. However there is more
adaptation for the water pumps with our water pump spacers.
Example: You can use a (-2) spacing LS1 water pump on a (-3) 5.3 truck
engine.
What this means to you?
The ability to use different style water pumps will allow the build to be
more universal. Most swaps are done to be as cost effective as possible.
Instead of buying a brand new water pump for your spacing just use ICT
Billet Water Pump Spacers to make the one you have work! Make sure to keep
in mind where the heater hose will run into the water pump when deciding
on what water pump to use, what intake manifold, which ICT Billet Bracket
to use, ect.
