Default stock cam and lift question?

here we go!! i measured the lift on the pushrod side and it came out to be exaust side #1 .295 #3 .300 #5 .295 #7 .250
now could this be a bad lifter or cam lobe on #7?

I'd guess something is wrong there, bent pushrod, worn lobe, etc., worth investigating further. Does anyone know the specs on a stock LS1 cam? I've been wondering myself.
