i run 3 12's and 2 amps and the pulley didnt make that big a difference but because of my camshaft my car idles higher than yours so i guess i am the wrong person to give advice on that subject. as far the belt, the goodyear part number is 4060855. however, goodyear is somewhat hard to find unless you order online but give that number to the parts guy at any auto store and they can cross reference for one they have in stock.
