I would guess that he is looking at forced induction cams in general. With a turbo setup, the shorter exhaust lobe is sometimes used to help with reversion. Same is true of the wide lsa. I believe blower engines are usually more happy with an equal or higher exhaust spec. You do want the wide lsa, though. I would look into competition cams. They have several forced induction and nitrous(same as forced) cams available. Remember that all cams with the same specs are not created equal. Comp. supposedly puts alot of time into lobe design, ramps, etc.
