Dwayne, glad you joined in! I mainly posted this to raise the level of awareness of the issue for those,like me, who were not aware of it. Since I never ran a Hyd roller, I never paid much attention to them, and even though I read almost all of the engine building posts on Moparts, I don't ever recall one talking about the high noise issue. I know for me, I am sticking with what I have the most experience with and that is solids. It is interesting to get all the feedback, and it mostly confirms that it can be a crap shoot. Not everyone wants extra horsepower at the expense of having an engine that rattles loud enough to scare small children and dogs! Switching to a hydraulic roller can be a significant investment, only to find you are one of the unlucky ones and then it is just tough luck. I hope we see more contributors and they tell us what brand of lifters they are running.
