Pulley set up ideas- need to buy a set

[randlej]

I am building a 351 W and want to run a billet aluminum serpentine system with only an alternator, crank, and water pump pulley. I have seen the March setup and would like to run something like that, but for less money.

I'm sure someone has come up with a good solution. Any ideas helpful. Still need to buy a water pump too so can go either rotation to make it all work.

Thanks.
