help timing a Gen IV 6.0L
So I've ran into a problem with timing a Gen IV 6.0L. There's two marks on the cam gear. With the motor in TDC of compression stroke neither mark lines up (obviously out of timing) there's an arrow and a line on the cam gear. Which one lines up with the crank sprocket gear? I've never had issues timing a Gen III ls motor. The cam is a center bolt style....

First, there were no center bolt cams in LS2 motors. The only thing I can think of is it's a VVT cam/ cam gear which is suppose to have a phaser on it. It's easy to determine though... With #1 cylinder at TDC, both lifters/ cam lobes for #1 should be on their base circles (closed) and then look at the cam gear timing marks. With a VVT cam gear, I believe the arrow is the mark that needs to be aligned with the crankshaft gear dot. That's some kind of bastard set-up you have there. Do you have a picture? Is it a 1X cam gear? Maybe someone else will chime in here.
