Just wondering I noticed this the other day but the pulley on my 351w (it's a 74 block) are V-Belts but the accessory pulleys from the 5.0 are 6 ribbed. Do I have to purchase a new pulley for the 351w? I live in Arizona I kinda need the A/C
Yes, you "can" make your v belt setup work. You would need to source a different length belt from your local parts store. As suggested above, it would be best practice to convert to a 6 rib serpentine setup though. Either way will work though.
