[Already Gone]

I want to replace the water pump in my truck. Looking for some real world experience with this. My truck is a 72 C10 with 350/350 with factory working A/C. The truck is stock and I don't plan on any wild cams or roller rockers going into it. The truck has 87,000 miles and I dont know if the water pump has been replaced. I plan on doing the long haul Power Tour within a few years so want to prep the truck by refreshing, even if they are working good, parts like a water pump that can fail without warning. Looking this morning I found an Airtex Brand, a little pricey, all aluminum water pump and am wondering is anyone is using one of these and would it be overkill for my sedate stock 350 truck. Any and all posts and ideas are appreciated.
