small block pulleys

thanks for all of the replies i havent had a chance to check back on here in a wile. it was a original 340 ac car i got all of the pulleys off of and i plan on hooking the a/c back up in the summer and it had the 318 balancer on the 360 when i got it and i didnt know until i put it in and it shook so bad it destroyed the rod berrings and the entire engine was out of balance about 500 grams so the machine shop completly rebalanced the engine and it runs smooth now as for the pulley problem i went to the junk yard and found a different 318 crank pulley with 4 grooves that lined right up with the p/s pump and water pump pullley with two groves that also lined up

again thanks for all of the help.
