Re: Erson Stage 2 Buick 455 Cam? WHAT IS IT?
Keep in mind that the factory Stage 2 cam is late 1960s racing technology. It had relatively low valve lifts, and very long durations on a narrow lobe seperation angle. Overlap was high, and vacuum was low. Probably too low to operate power brakes. It was more likely than not, designed to be used with an open exhaust. I am not saying that it is not a good cam, but agree with motorman that it's greatest value would be to someone building a vintage (iron head) Stage 2 motor. With all the cam grinds available today, I would view the factory Stage 2 cam as a nostalgia part.
