Help Please!!!! engine wont run

Thanks for the input, I will take a really good look at the cam and lifters tomorrow. anyone have an idea on where to start troubleshooting the ignition? I don't have money for the trial and error method so are there ways to check the components individually? my plugs, wires, cap and rotor are good for sure. Can something go bad in the distributor, box, or coil to cause this?
