Harland Sharp Rockers and Comp R's I did a search for this, but I found so much conflicting information I decided to post this.
I have a trex cam in my car and it is not making power past 6000 rpm. I have found on the board that the Comp R lifters are to blame, and I have found that the Harland Sharp Rockers are to blame. I need some fresh input on this.
I thought the Trex should make power to at least 6800. Any and all help is much appreciated.

Neither is to blame. The problem is that you are using a non-adjustable rocker with a lifter that requires an adjustable rocker. You are puting excessive preload in a lifter that isn't designed to have a lot of preload and that alone is killing your top end power. Those lifters are only supposed to have .002"-.004" preload.

a guy at Thunder Racing told me I should just use stock rockers and an O.E. Replacement lifter, I guess like a standard comp. Anyone out there using stock or equivalent lifters and rockers on a cam as big as mine?

do you think that I would be better off to use stock rockers with stock or stock equivalent lifters? I'm kinda confused as to my best course of action. What exactly do you think I should do as far as my lifter and rocker choice together?
well as is there will be a lot of work to do to change the lifters. With the RPM you are wanting to turn with that cam, I would change out to some adjustable rockers versus going back to stock pieces.
