Symptoms of wrong cam installation

Ok, so I have a question about degreeing the cam. My 360 is not running right, and I have come to the conclusion that the cam is probably retarded. It idles ok, but it seems like it is just not making any power. The car has 4.10 gears but will not spin the tires. Period. If I open the throttle in park, it will rev up, but it is slow to respond, and always smells rich, even with the idle mixture screws leaned out. I have an MSD 6 plus and MSD billet distributor in it, I have played with the timing, both retarding and advancing, and while it clearly prefers advance, it is still a complete dog. I ran a near identical setup in my last Dart, and it was a screamer, even with 3.23 gears and stock Mopar electronic ignition.
Any thoughts or suggestions are welcome, I installed the cam "straight up" at least according to the marks on the timing gears.
Thanks
I will have to look up the cam specs and post them later, can't remember off the top of my head and I'm on my way to work.
