Did I slip a tooth?

Dang car won't start.
New distributer, new cap, rotor, wires and coil.
I pulled #1 plug and the valve cover to make sure I didn't put the distributor in backwards and it still won't fire?
Not even a pop, she just cranks. Carb is pumping fuel and I have fuel pressure.
Battery is also new and cranking fast.

The only other thing I can think is that the timimg chain slipped?

Any ideas on what to check or what I should be doing?

71 dart, 318.

I'm at my whits end whit this.

Thanks again for your time and advice.
