start with something simple like the set screw that hold the rotor in place or the order you put the spark plug wires back on...see:

"and I am wondering if I could have installed the cam 180 degrees off when I put her all back together? What would happen if I did?"
The cam runs at 1/2-speed of the crank. Turn the engine over one full turn and the cam will be in the right orientation. Verify #1 cylinder is at TDC by putting a pencil or chopstick down the #1 spark-plug hole as you're turning the engine. Then check TDC of the crank with the notch on the bottom of the bell-housing. Then verify that the distributor rotor is pointed to #1 cylinder. There should be TWO bolts that holds the rotor to the front of the cam. A lot of people forget that 2nd bolt and the rotor ends up spinning so that it's aimed somewhere else when the spark fires. |

Been througth all of that. Rotor is tight, everything lines up at tdc. Getting spark at the plugs, noid light flashes, I even pulled the fuel rail and watched the injectors spray. This is bizzare. I've got 150 psi compression across the board (±5 psi), hot spark, and fuel. It SHOULD run, right? But I don't even get a back fire or stumble, nothing, nada.

It sounds rather like spark timing to me.
150psi sounds good enough. Since you have fuel, even if the fuel timing was wrong or something, it should still start. I had the firing order out on my car. It would turn over endlessly, not even start to catch. I was worried I had something seriously wrong.
