Mark, with the resistance to change you have on some items, and your normal recommendation to stick with V-belts, why are you even thinking about a dual-belt serpentine setup? Are you missing some of your original parts at this point? Is the new engine going to be a 28oz or a 50oz engine?
If it's just to keep with a standard rotation pump and fan, then why not stay V-belt for less cost and more fan clearance? If it's just to keep the mechanical pump, then why not stick with V-belts for the same reasons?
As has been said, the V-belts work fine for most situations. If you need more grip due to a larger alternator upgrade (you are not planning that as well, are you?) then workarounds have been figured out for that two. Just run a larger alternator pulley, or a dual-groove alternator pulley.
I'm just asking because adding serpentine at this level seems like a huge waste of money just to have less, or certainly no more than normal, room for your fan near the radiator.
Seems like there was a discussion about this just a couple of months ago with pictures and discussion about clearances. Was that your thread Mad? If not maybe someone's got a link to it if you missed it the first time around.
Maybe I'm off base and the clearance issue is not that big a deal with certain kits, but it seems like it would be on most of them.
March Performance used to be the go-to for serp systems, but at least back in the day they were too long for Broncos. I've heard that since then they have added some lower profile kits that would offer more fan clearance with the radiator, but have not looked into them.
