We haven't set definitive pricing yet, but it will be a little more than the current 408's, in their similar versions. There's more machining/cost in the roller setup. However it won't be some crazy increase. Usually when we do a roller, and flat tappet version of something, the roller version is what i'd consider "a hell of a deal" for the roller cam upgrade. You guys will be the first to know when we have it online, and pricing, etc.
