measure valve lift at retainer
I'm measuring for pushrod length and have a dial indicator set up on the valve spring retainer. I'm using a solid lifter, adjustable pushrod, Proform full roller rockers, the real valve springs I will be using.
When doing the pushrod length checking the most valve lift I'm seeing is .448 and that's with a pushrod that's way too long. I've tried 3 different rocker arms from the package and got .444, .446, .448.
When using a pushrod length closer to what I'll need (roller rocker tip pattern located in middle of valve tip), I'm getting only about .439 lift.
Cam card states .311 lobe lift (.467 with 1.5 rocker). I've previously checked this by placing the dial indicator on the edge of the lifter and it's ok (.311).
I'm thinking I'm not placing the dial indicator properly on the retainer.
Is this lower lift I'm seeing to be expected or do I have a problem?
