dual belt (serp and v) pulley

[RootBreaker]

Ok so I have been googling and I know I saw it while browsing from work but cant find it now.
I am going to put the cs144 Pontiac trans sport alt in my truck and it has the serpentine belt pulley. I was just going to throw a V belt pulley on it but from what I'm reading up here is the V belts struggle to keep the higher amp alts running.

so is that true or will I be ok with a V belt? and if not.. where can one source the dual belt pulley or is there a special name I can search for?

Best quality belt and keep properly tension-ed they work. V belts just don't have the surface area required when that alternator has a heavy load. I went thru several belts shredded by a v belt drive before converting to serpentine belt setup.

Would double v belt be better?

twice as much surface. It will last on one is there is no slippage. The belt will not live long once it starts to slip.

See if you can't find the "semi serpentine" (I know, a misnomer, but whatever) setup from some of the mid-late 80's cars and trucks.

The ribbed belt goes on the alternator/crank/waterpump, but runs a v-belt for PS.

FWIW, I've slipped even the semi-serpentine belt when the CS130 alternator started trying for max output due to a bad adapter pigtail.

I believe you're looking for p/n: 14088683 crank pulley and p/n: 14088685 water pump pulley. I just did this on my truck and you might want to upgrade the alternator mount, the long bolt broke off in my passenger side head. I got a cheap turnbuckle style on Amazon, but I had to grind the case on my cs144 to clear the turnbuckle.
