i dont know much about cams but from what ive read and heard from many people is that there are much better choices out there than any of the alphabet cams. With a turbo setup i would go with a custom grind cam and not an off the shelf one.
....anything will work. The issue at stake is really how well will the B cam work vs the F. I think that the F would work much better. Alphabet cams are very good. Don't listen to to all the "haters".
