Old magnum MP cam info

You guys said something about "just" an R/T cam this is the one, they had that and the one I'm talking about is the "R/T+10". I don't remember or have the specs of the regular R/T cam here. But the "+10" was supposed to mean that much more HP over the R/T one. Don't know that I'd go thru a cam swap for a measly 10hp, I wouldn't swap between these, but if starting from stone stock and had to get one or the other as compared to that, and was given the choices of "cam 1" with "x" amount of HP and "cam 2" that claimed "x plus 10" HP and they were similar money id probably go for the 10hp bonus. ... Though the seat of the pants probably wouldn't notice the difference between "only" 10 hp
