I am building a 400 that originally had AC on it. There will be no AC on the car it is going in after the build so I need to get a two groove crank pulley and a single groove water pump pulley for it. Can someone tell me what combination of diameter and depth of each pulley is that I need to get? Thanks in advance.

The pics on Bouchillon's site should help. If you need re-pop pulley's they have you covered. When I needed pulley advice they were helpful on the phone.
