Water Pump Pulley Help Please
 
1 Attachment(s)
On our 86-91 BBC trucks the alternator belt is a serpentine belt. I was wondering if anyone has the part numbers for the water pump pulley that also has the single v-belt groove as well? Im trying to convert my Pro-Street BBC over to this to ease my charging issue. Pic of setup For reference..

I have the later model long nose pump and currently have a double groove v-belt pulley. What I'm wanting to do is keep the double groove but make the alternator a serpantine belt like the 86-91 motors have. If that makes sense.

This is a pic of my setup but it has a cs130 amp now and has been rewired.

Ok so you have serpentine belt. on the out side, but you have a two belt pulley on the water.
If I got this right now. You want a serpentine belt on the out side of the water pump pulley and a in side V belt. Wright

Then you are looking for the 84-86 Firebirds / Camaro could be the V6 305-350 set up. I got one of these for my 76 Lemans . NOT Know the #'s on them of hand not sure where I put it to look at them. Think the Monto Carlo had this set up to but can't remember what year and what motor set up.

Close. I just have v-belts now but want to replace the alternator belt with a 5 rib serpantine belt just like what's on the 454 setups from 86-91. The first pic of the black truck is my 86 that had the setup I'm looking for. The red truck is my pro street that I want to copy the serpantine setup from the first one. I can find the matching crank pulley but I can't find the water pump pulley but I think it may be the same as the sbc like you mentioned earlier but I can't find any part numbers to prove that one way or another. I found a smaller wider pulley for the alternator v-belt so I may just scrap this idea and go with it.

Found that one to but says 305/350 so not sure it'll fit on my bbc. But it's as close as I've found to what I'm looking for.

Try to look in the scrap yards junk yards for the 84-86 Firebirds / Camaro could be the V6 305-350 they have the set like this if you find one grab alt or ( just the alt Pulley ) if you have a Batt impact gun, water pump pulley, belt or mark down the size, keep eye on e-Bay for them.
