from here i can calculate dimensions and order one-piece aluminum spacers from aluminumspacers.com...
the water pump pulley lined up to the crank pulley with 3/16" of spacing behind it, the alternator needed about 11/32" of spacing and the power steering pump required about 15/32" of spacing.
hopefully, nothing got pushed too far forward.

now i need to determine where the belt tensioner pulley will have to go, and how i might have to shape a bracket to mount it.
i have found various resources online which cover the basics behind this kind of modification.
there seem to be various opinions about whether or not power gains are possible with a serpentine conversion, but to be straight up... i'm just hoping i'll never have to fiddle with the v-belts again.
please feel free to chime in with your comments at any time.
thanks for your interest!

Great idea on the belt conversion. The setup looks very similar to the accessory layout on a LS Corvette. The only issue I see with what you are doing is that the water pump pulley is often smooth so the belt can wrap around it on the driver side so you get more belt contact on the balancer. Can you get a Pontiac water pump set up for reverse rotation? You'd need that if you swap to the smooth WP pulley.
