hey, welcome to the site. Scroll to the very top of this page and click on the "performance trucks" link, use you same login and password. That site has more truck-specific help.

The stock pumps are good. LS motors don't have cooling problems based on poor pump performance. The only detail to consider is if you are planning to go to an LS1/LS6 intake which is a popular swap for some truck people. I believe you have to go with an LS1/LS6 type water pump and pulley/accessory package.
