help with cams
 

Hey guys new here. I need some help with a set of cams. I don't know sh!t about them. I am looking at buying a set of heads with these cams already installed. Could anyone tell me if they are stage I,II, or III. Here is the info that I have: Grind 267/282, duration @ .050 226/235, valve lift is .540. Thanks for the help.

I think they are stage 2 by the numbers you provided

stage numbers are arbitrary and not indicative of any actual level of performance in the real world. That said, the duration and lift would say that the cam you listed is about mid-level aggressive probably something like an XE268 from comp. The lobe separation angle will tell you how aggressive the idle will be and will define a lot more of the RPM window and powerband characteristics than the duration and lift alone.
