**71 Dart wont start after CAM, Timing Chain and HEAD Cylinder install** HELP

OP, when you lined up the dots, was the crank sprocket dot at 12 o'clock and the cam sprocket dot at 6 o'clock? You need to use a straight edge to make sure the dots are truly aligned with the centers of the cam and crank.

The mark on the damper a should have been within a few degrees of the 0 mark if you put it on with the dots on the sprockets still aligned.

If the dots are aligned as above (crank dot at 12 and cam dot at 6), then both #1 and #6 cylinders are at TDC, but it is # 6 that will be firing with the dots aligned this way, NOT #1.
