It is a 94-97 exhaust cam with the back lathed off. I have a predrilled cam gear that goes with it. All you have to do is plop it in your car, set it according to factory specs, and you are golden. I think there was someone making 137whp with this. With a megasquirt, this cam, and i/h/e I ran a 15.5 quarter in my 95. Never dynoed it though. I would estimate the same numbers though.

This is the thread referencing it.
