Mine was about 5750, now it's 6000.Yes ,that was a surprise for me,the RPM blockade,no more then 4000 wow

The lack of lube on the roller bearings is a well documented shortcoming of the current OHV design, failures resulted when they raised the camshaft and didn't allow sufficient lubrication on the cam-roller interface.
I've got about 250 idle hours and 60kkm's, i inspected my roller bearings when I pulled the cam at 55k km's and they seemed fine, but I changed the rollers as cheap insurance. It's really hit and miss with these hemi's.
PS There no such thing as a "hellcat lifter", the part numbers are all the same.
I didn't do it for that reason myself, I did it because of the sound I didn't like and it did nothing for my fuel mileage that I could tell. Also something else that doen't have to work and go bad. There's a lot of things that came on my truck I don't need or use so I'd get rid of them also if I could.Curious if someone will provide a mechanical explanation of why disabling MDS will have a positive impact on cam/lifter failure. I’m seeing a lot of anecdotal input related to it but I can’t seem to find the mechanical reasoning behind it. Thanks.
