Crane 308B Fireball cam. I told my man that ease of starting was paramount (just thinking of you guys...) so I hope he didn't steer me wrong with some high-lift/mucho overlap bumpstick.
Apparently Bones likes 308 because it's got an indexable gear; you can run normal timing, or retard/advance the cam timing 4 degrees which would move the power up or down the rev range...
