Magnum swap questions

Again go back and read my post, I say in it that it might not be advantagous but probably will be. I mention nothing about anything negative about going to 1.6 rockers from 1.5. The only reason on my second post I say that it could lessen performance was in rebuttal to you making an insinuation that I was saying the effect would be negative and was trying to give an example of how it could be negative. I didn't say it changed the duration I said that if you are at the limit of the duration the higher rocker ratio could effect the performance this is because of the added rocker ratio the opening and closing rates of the valves are faster which makes the engine think it has 2 to 4 degrees more duration. Again the gain might not be there but it probably will.

FWIW, Comp's catalog lists specs with the 1.6 rocker ratio on their Magnum specific cams not 1.5
