Default Cam with no tune??

I was just wondering if I can start my car after the cam install with the rear o2's unplugged and stock programming. I only want to do this so I can heat cycle to retorque everything and make sure all is well before I get it tuned. I was also curious if you can pass emissions with the rear o2 sensors tuned out?

depends how agressive the cam is... any mild cam will run and drive no problem its when you start getting into the wild cams that will have a hard time running on a stock tune.
