Actually, part of the reason that JWT cams are better then BC is due to the fact that JWT designs a modified lobe centerline into their cams to advance or retard the cam a specified amount from the stock centerline without having to use gears. To my knowledge BC did not put that much R&D into their cams to modify them like this, so using gears with BC cams can bring your powerband down into a more useable range. As we all know that has been the main complain with BC cams. They do give gains of up to 15 hp or so, but its all in the top end of the RPM band. If you already have the cam gears, it will waste nothing but your time to play around with settings, however if you do not plan on dynotesting after each setting, I would just say run them straight up. The butt dyno is very rarely accurate.
