Lets talk Roller Cam Lifters.

next question.
What is this reverse roller lifter i keep hearing about.
what does it do and why/!??

I went and tried to find the thread that it was take about in. But couldn't find it. should have asked the question them.
I think it was a Jones solid roller lifter???????
Something about that lifter would have changed the cam spec a little?????????
Hope that jobs someone memory on that? Maybe i was just dreaming.......not it was on one of these thread in the past week or so.
I tried to use the search button also and got nothing so the spelling could be way off as well.
