A couple of days ago I described the method I called something like the "symmetrical center roll over method" for selecting push rod length for best valve train geometry. Well, even though this meth

It seems to me that changing push rod length can satisfy one or the other criterion, but not both at the same time; either you get maximum extension at half lift (the 90 degree angle point), or you

I should clarify that I think it is possible to get the contact patch symmetrical with this approach but half lift will not occur when the tip is at the centerline of the stem but rather somewhere pa

This part bothers me. Wouldn't the movement be highest and equal at lowest lifts and again at highest lifts? Your working on equal parts of the arc on both sides of 90 degrees in this method. Frank

Yes, Comp Cams is who I was refering to as my push rod vendor. That is the method I used which I now believe to be incorrect. the second method I described and that Bob posted a description of seems

Hello Listers, I use roller rockers manufactured by Precision Valve Systems as recommended by the guy who set up my heads. They are a true mid lift or net ratio at zero lash design. The top of the ro
