Camshaft comparison question !!! HELP PLEASE
Dear friends,
I have encountered the above 2 spec sheets , for 2 sets of camshafts. I was told the 2 camshafts were actually the same, it is a matter of setting up.
Furthermore, I was told that the XXR 01 would rev to 6,500 rpm, while the XXR 02 would rev even higher to 7,000 rpm.
And yet, I was told the 2 sets of camshafts were of the same.
Could someone please help shed some light on me !
(Please find the attachment sheet)

Lash affecting cam timing
A very simple answer to your question:
The clearance (valve lash) changes the opening and closing events, thus changing the amount of fuel/air flow that the cylinder "sees".
This changes the rpm range that horsepower and torque is produced.
There is a lot more to this, but I hope this gives you some insight.
