I'm in the middle of a 6.4 cam swap in my R/T and before pulling the cam out I had a few questions, most of my searches have come up with non-VVT info. I was planning on leaving the oil pump attached as I did on my LS2 GTO but can't find crank timing mark that way, has anyone else done it this way ? It appears when I'm at TDC the crank keyway is at approx. 1 o'clock or so and I've marked that very well, is that true ? Also is there anything special when pulling the phaser and cam sprocket off ? Just pin back the tensioner and pull it from there ? Any help would be appreciated, thanks !!
