Yeah, I know exactly what you mean. The timing definitely seems to be retarding. I am sure that the camshaft is in proper timing with the crankshaft. I've checked both physically and with a timing light, it wasn't my timing light so I can't check and see what the timing is doing when it's bogging. The bogging only happens when at idle and giving it more than 20% throttle. If I want to drive, I have to barely touch the gas until the motor reaches 1500~ RPM and then I can apply more gas. Once I am driving, it is completely pointless to give it more than 20% throttle because it doesn't produce any more power than it did. If I do it is only for a second and then it picks up again.

As I mentioned in another post, it seems similar to the symptoms for a bad Crank Position Sensor (as listed here), but Tony H said that it would sound different.

I'm going to the junkyard today to get parts for a fuel pressure tester. Hopefully this will shed some light onto something.
