[Reed Granrt]

First lets make sure that we understand. You cannot make the rocker arm have any more rocker ratio than what it is. If it is a 1.7 then it is 1.7. None more nor non less. If you want to delay the full ratio to come in later in the lift, then yes you can have the cam read too large on lift, but only if the cam is GROUND wrongly to start with. By wrongly, I mean it was not ground correctly to start with to get minimum scrub pattern and minimum friction losses thru out the variable ratio of the rocker arm. The cam grinder ground it to have the pushrod some length other than perfect use of the rocker geometry. Is that what you want? I dont know any good cam company today that doesnt use a CNC cam grinder some place in their facility. And believe me they can repeat within a couple of tenths of a thousands. I have worked in a facility that would grind a 100,000 shafts per week and hold +/- .0002 per shaft. That camshaft will be much closer in tolerance than you will ever be able to measure. If you want the camshaft to your spec, they can grind it. If they cannot, why are you purchasing from them? One thing I do know, you never ever get what you do not pay for. If they cannot hold the accuracy, whether it be master or CNC, on one lobe, then what makes you believe that all 16 lobes are exact. No matter what push rod length you have, the lobe has to be correct to start with and no matter what lift you have, YOU want to get to that lift with the least amount of frictional losses available. TO ME any thing else is unacceptable.
Damn here i go again on my .02 cents worth. Geez I sorry
