Truth about roller cams.... BEFORE you make the switch......

I probably put 20-30k on it in that time.

Between my Ram , Barracuda , Dart , Dual Sport and the motorhome I doubt I will put anywhere near 300k on all of them in the next 15 years

I figured they are overstating the problem, and remembering what a Ford and Chevy distributor drive gear look like, I don't blame them. Obviously yours are well maintained and I do hope they last forever.
