Did you run a search yet? There are pulleys from ATI, ASP, March, Powerbond, SLP (same as Powerbond), and maybe some additional. They're all going to add about 10 rwhp 10 rwtq to any given setup, except for the ATI which is 10%, not 25% underdrive. Most people change them out when replacing the cam, because the pulley has to come out anyway for that.
