360 LA engine crank no start

First make sure that the engine is on TDC, I use 15 degrees before TDC.
then check rotor is pointing to number one spark plug terminal.
If this is correct, is the carb pumping gas? should be able to see it when you pump the linkage, the accelerator pump should squirt
Put a phillips screw driver in to one of the plug wire and have it be touching a ground
crank it over and see if there is a spark from the screw driver to ground, if not then there is something wrong with the wiring, check the start cycle for spark and then the run cycle, mopar has the two cycles of flow of electricity. Use a light probe to check this at the ballast resister terminals.
Good luck
