Pulley help

[Blue68Camaro]

I need to order some nice pulleys for my motor but not sure about how many grooves to get on each.
I only have the crank, water and alt. Do i use 1 belt around all 3 or 2 belts ect?

Any info would help, thanks.

anybody?

I am thinking about 2 groove on the crank and water pump and 1 on the alt. Sound about right?

march has great setups but you pay!!!! (serpentine system), 1 belt I believe. 1 belt is kool for looks, seperate belts you dont have to loose everything if it jumps, or brakes. its kind of up to taste. drag, its v-belts or gilmer belts.David.
