is this possible?

Sam, 8388, does seem to be a knowledgeable guy. I don't think he is trying to BS you. It may be his car is just a factory freak. Or maybe he isn't the original owner, and someone else had the intake off. Or maybe he uses a rather gracious dyno. Who knows.

I think it's safe to say that the average owner won't make that kind of power with simply adding a Desert Development exhaust and timing the cams.

And I've never done it, but watching the videos on the cams, aren't they basically timed by the process of installation? Which is to say you have the assorted crank and cam pins in place, and voila it gets timed? I didn't know there was much room for error in that other than perhaps play in the pins.

What I am fairly sure of is that if there was a huge amount of power to be made timing the cams, then the folks that make their money selling performance to ZR-1 owners would get on board with that.
