What would be a normal general (PSI) range expected on a cyl compression test on a stock Hemi




That is what I was trying to figure out however I think I know it should probably be at least in the 130-140 psi range. I get 100 on all of the left bank cylinders and 85 on three of the right bank and one more cylinder at 75 psi. This is cranking with the starter motor, 3-4 revolutions. Obviously something is wrong, the engine runs but not a good idle and lot's of hesitation. It does go wide open throttle with no back firing. I am wondering where to start. I know nothing of the engine except it was supposed to be rebuilt 3k miles ago, maybe the cam is worn but there is not excessive clatter?
