It will depend on the motor. If it's a 302/351W you will have to get a different water pump since they run the opposite way with a serpentine belt. If it's a 460 you can use the same water pump. I will be attempting a serpentine conversion on my 460 this summer.

I did it on my Cobra Replica several years ago..289 Hi-Po. Seems that a couple bracket fabrications...idler pulley... and a water pump is all I needed..Worked great..

Why wouldnt you want the v belt system? I liked it because if one breaks, you only lose one accessory, whereas if you break a serpentine, everything stops. Also, a v-belt is cheap compared to serpentine belts.

Thats only partially true. One serpentine belt may cost about $30, but if you replace all your v-belts at the same time at a cost of $9 per belt times 3 or 4 belts, the cost is practically the same.

You are right about lose one belt lose all accesories. I do make sure I have a good belt on my serpentine equipped vehicles and always keep the old belt as a spare in the vehicle should such an incident occur.

I am trying to convert my 460 to eliminate the annoying PS setup which causes squealing at high rpm. It squeals with old belts and new belts so I am hoping an entirely different setup will work. The 460 setup uses 2 small serpentine belts, so if one does break I wont lose everything.

best way is to go to a u pull it
strip the pulleys and brakets needed from a donor
you can also look to a 3G alt upgrade while pulling the parts
