I put a newly rebuit 440 in my Challenger. The engine turns over freely by hand.( I know this from putting priming the oil pump and turning the crank. Also I know this from putting it in time.) The car rolls freely in nuetral. I have a new battery in it as well as a new mini starter.

I went to try to start it for the first time and do the "cam break in", and all I got was the infamous starter "clunk". I put a battery charger on the battery and it didn't seem to matter. I made sure all of my connections are on and tight. I have lights and radio when the battery is connected. I tapped the starter with a small hammer and it still didn't make a difference. Does anyone know what could be keeping it from turning over? I hate the thoughts of pulling the starter back out and I am thinking since it is new, that shouldn't be the problem. What do you guys suggest to try? Thanks, Jason
