i just installed a newer motor, and its idling a little weird, and bogs when i hit the throttle. Every time you try to idle upit runs rough. im going through checking vacuum lines. im still searching google for a vacuum digram, but could it be cps? or dist? anything else?

Dist off a tooth or two.

Low fuel pressure.

It would need to be a LARGE vacuum leak. Small vacuum leaks will raise the idle.

I would re-check the dist.

Getting old, I had to go look at your other thread to see what year. Is the EGR hooked up and is the valve intact and sealing?
