69MOPE Once again (you made my 8.25 3.55 SG swap happen) you are here to the rescue. I have done the timing belt on another 3.5 (2000 Intrepid) so I am familiar with the swap. In that case, it was a preventative change. In this case, my biggest question is, Can the slave cam (the one without the cam sensor) be off my a tooth or two without valve clash? No one seems to know for sure. All info just says that in '99 when Dodge went with the all aluminum 3.5 it became an interference motor. But my math / logic skills tell me 1-2 teeth should be only 12-24 degrees and that the valves COULD still be fine. As I said in the OP, there is no bad bangs or clangs when cranking and my son told me he did not hear anything when it died.
