I'm going to adding a powerbond underdrive crank pulley with my cam swap here in a few weeks. For those running the powerbond crank pulley what serp. belt are you using?

Try to look these part #'s up using the website.... Besides If I'm not sure on what size belts to order then why would I order them online? Too much of a hassle shipping back incorrect parts. Thanks anyway though

I'm confused. Bluefire provided you with the p/n's.

***edit*** What underdrive will you use?

The company selling you the pulley should also have the belts. Youll also need a a/c belt from what I remember.
