Everyone seems to like the pulley upgrade for extra horsepower. What exactly does this upgrade require? Is it a job for the moderately capable home mechanic? How much $$$?

I'll leave the do-it-yourself advice to those more experienced but have a caveat for you. If you intend to put a camper on this rig or tow anything substantial, you might think twice before going with the power pulleys. I have a 98' 4.6 f250 super cab and experienced severe overheating problems when traveling with my camper on going up hills at 3k rpms. In all fairness I have to say that without the camper on, I never had any problems although i have to say i never noticed any pwer difference either. YMMV

Boss 46.... The job is easy. Probably the biggest problem is changing the alternator pulley. This can be tricky on the truck and/or if you don't have an impact wrench. I just took my alternator off and had someone switch them out. For reference, I used a 3 piece set from Ford Racing. The main pulley on mine took more effort than the water pump pulley, but I think mostly just because you have to do it from below. I don't experience any cooling problems. When you put the new pulleys on, use a piece of string to measure the size belt you will need. This can save trips to the parts store.

 

My pulleys came from Steeda, which require switching to a Mustang (6 rib) belt. Had it done in the d---e dealer where I work. Haven't noticed any difference though & if I bought another truck , wouldn't do it again. I'm interested in knowing what a lower temp thermostat does, however. My truck is listed elsewhere under ENGINES, so I won't bother here.
