Thanks! That was some informative reading re: the V10. So, according to what I read, the stock rocker arm for the V10 is a 1.6 ratio. I also read the comparison between the V10 rocker arm/pedestal and the V8 5.9L rocker arm/pedestal. I would love to know if the mopar V8 pedestal (#53008283) which is readily available from many different sources, would be compatible with the V10 rocker arm (#5245335). Has anyone tried this combo setup and did it work?
