Can't start my 408!

to turn it over with the plugs out is not a good plan for a couple reasons. Intake valves will let more fuel in the cylinders. Explosive vapors escaping through plug holes. Best to just let it dry. Hope thats all the problem is.
Meanwhile check the ignition again, i.e. the drive dog in rotor button, proper wire location on cap, etc.. I
if you have all stock components there you can set the distrubuters spark advance vacuum port square to the block and it shoud start/run there.
