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

• Hi, I recently in stalled a new Cam with lifters, Pushrods and Aluminum Heads. Car was running prior to installing these new parts. Engine is cracking, but that's all its doing! also carburetor shots random fuel mist when I crank.
• Here's my question when I installed the timing chain I made sure the two dots lined up and piston 1# one was at top dead center. However the indicator line/Timer mark on the harmonic balancer was not aligned to the zero (0) mark on the plate tab. Was this also suppose to be aligned?
• Secondly, I didn't have to remove the distributer as the intake manifold was not obstructing it. I made sure to label my spark plug wires to the corresponding cylinder. Will TDC change even though I didn't remove the distributer?
• It has new spark plugs, fuel pump, spark plug wires and I've tried running it hours and even a day later in case it was flooded.

Any feed back would help please.
