Holley is known as the "LS-Swap" company supplying everything you need. They now offer water pumps covering all non-supercharged applications and all belt alignments. Maybe your donor's engine has a questionable water pump, or after you started fitting that LS under the hood you notice the accessories interfere with things you didn't expect.

Holley's 22-102 gives a quality-reasonably priced option that fits under your hood AND works will all the truck accessories. Holley just keeps making swaps easier and easier.
