If you're pushing 200#'s of compression..I doubt timing is off on cam. When you jump a tooth or two and cam retards, the intake valve closes so late (if nothing is bent) that compression drops.
You've still got something out of whack.
We've got compression...we've got fuel....we've got spark ..right?
Does it ever sound like it's trying to crank? Does it kick back or anything? Pop out exhasut/carb? Sure it's definitely in time on distributor?
There's something real simple here that's not adding up right and we're all gonna smack ourselves on the forehead!

you know make sure the gear on the crankshaft didn't break that key thats holding it on.....that would account for a noise and would account for the timing shifting .....

,,, nothing to add because everything I've thought of so far has already been talked about,,,Maybe it's time to just forget everything that you know (mechanically) and start from scratch. Go at it step by step and stop second guessing about this that and the other,,,,,kinda walk away from it for a day or two if you can and dont even think about it. We have some VERY knowledgeable people on this forum and sooner or later it'll be solved, but I bet yer anxious to hear it run again 
Peace,,,Moosie

Before I removed the cam/valvetrain/timing set it would only turn over. Didn't even grunt like it wanted to start. Like I said before, it'll probably be something so simple I'll be embarrassed to admit it...but I will!

I wouldn't worry about putting all that stuff on. No reason you can't crank it and let it run a few seconds with no water. Won't hurt a thing.
Just leave bare minimum stuff there to crank it. It doesn't need all that stuff so you don't have to mess with it later if you have to go back into it.
