Going with a problem with the cam after today's tests. At the long block stage, we put the rocker gear on one side & it took 105 lbs on the torque wrench to turn over. Removed that side & did the other bank & still had the same result. The cam bearings are good, I gave them a polish with the scotchbrite when I was cleaning the block. But I'm pulling the cam & going to get it checked for straightness. Although it spins easy, it didn't spin easily unassisted, I had put that down to a burr on the bearing from a lobe catching during installation. Stay tuned.
