I have purchased a Mopar Performance P4286681 camshaft but i haven't received any card with it.
Does anyone have a the card for this cam? Can you send me the specifications for it? Maybe a scan.

Also, do you know the operating RPM for it?

On the web i have found this information about it but I don't know if it is accurate:

Duration 276/276
Duration @.50 ???
Lift .490 / .490 (1,5 rocker ratio) .523 / .523 (1,6 rocker ratio)
Overlap 64
Lobe separation 106
Instaled Centerline 104
Intake Opens 34
Intake Closes 62
Exhaust Opens 66
Exhaust Closes 30
Intake Valve ash ????
Exhaust Valve Lash ????

Any help? Regards! Martin

Go about 1/2 way down this page and you'll get all the info Mopar put in the catalog. The lash numbers are there at least.

I have found that the recomended valve lash from MP is:

Intake .016
Exhaust .020

But I wanted to confirm all the other info, specially the cam events.
