BJR. Shrinking cams(?) possibly so. That's why it should always be checked(measured) also rocker ratio isn't always true. What I am saying is... we loose lift from what the actual lobe lift measures, and what the pushrod measures or "see's" from the lifter. The rocker ratio has NO effect on the loss of "motion" transfered from lifter to pushrod. regardless of lift or "shrunk" cams. I measure ALL of my cams as installed and I can tell you that whatever the lobe lift measures...less .010...X rocker ratio, is what you will see at the valve (hyd.) or less lash (mech). If the rocker measures 1.46...then use 1.46 x lobe lift less .010 and that is what you will see at the valve as installed. The fact remains..small mopars do loose lift(motion) from the cam(lobe) because of design...lifter is not in plain with pushrod..now introduce off set rockers (W2, W5 ect.) and the loss is compounded. Does anyone remember what DLI. did to remedy this? Terry.
