I just bought, as a kit, a Jackson racing supercharger with a bbk and Crower Stage II cams. Will my car still be reliable with this combination. Or would it be better to stay with the stock cams or buy some Stage I cams. Also if I use the Stage II's can I use the stock valve springs and retainer, if they do have to be changed do they have to be Crowers (very expensive) kit. thanks for the help.
