Here is how it reads just so you see what I am seeing:

These Specs are for cam installed @ 107.0 intake center line

Duration @ .050 Intake 226 Exhaust 234
Lobe Lift .3200 .3320
Lobe separation 111.0

post #37 i showed what lift would be with a 1.5 rocker or a 1.6 it is the rocker that add to cam lobe lift the cam has a lobe lift of .320 x by 1.5 or 1.6 what ever rocker Ratio must be added to cam lobe lift

I was reviewing the earlier post:

"you posted that the cam was .498 ex lift---that will be at the valve of course and with a 1.5 rocker means that cam lift will be aprox .332------ put an indicaror on the lifter and see how much lift your getting"

Just out of curiosity - if I am measuring from the pushrod side, I would look for .498 - yes?

And Pat, I have been trying to find the time to call you around 9am my time so that it's around your lunch, I just have not had the time to do that from work - seems like something always comes up and by the time that I look at the clock, it's closer to 3:00 your time... By the way, I checked out your site, very nice!
