What are the cam specs for an nhra 500ci prostock engine?

They are insane. Over an inch of lift and the duration at fifty is high 280s low 290s. But they use a lot of lobe separation angle (116-118). They will idle at a decent rpm. Those cams KILL valve springs. They go through a set maybe every two/three runs. $4000 a set?? But you are lifting a very large valve an INCH @9000 rpm.
