At idle, close to 19 in/hg.  Probably not much lower than that when running in park around 2200 rpm.

The Beast lives! Fired up and ran for a half hour good oil pressure,  with both fans on the temp never got above 188. Still doesn't run real smooth getting a malfunction code 34 it doesn't like the MAF from my car plan to start switching Parts back now like coil, computer, maf one at a time... also the power steering pump is shot and squealing but other than that no leaks anywhere and I'll count today as a huge success, step forward!!!!

Note the comment at the bottom of the page about 1400 rpm

Damn, you work fast!  I faintly remember being young and fast!  LOL

That is great progress.  I would check for good, steady vacuum at idle.  Also, if the injectors have been sitting for a long time, then they may be gummed up.  A couple of cans of Chevron Techron may help that.  

Check for vacuum leaks around the bases of the injectors caused by dried up o-rings then check all the usual spots including the bottom of the egr where it bolts on the intake, around the vacuum block on top the plenum, back of the plenum, throttlebody, pcv, and so on...

Working to fast I guess, had the MAF backwards...du mb...flipped that around, restarted, runs much better but at idle it still wants to die after a couple min and still throws same code. Vacume gauge at idle is steady 19 so that's good. Maybe the intercooler has a leak so tomorrow going to start it and shoot some flammable brake cleaner around it and see if idle increases. Also crossover had a bad leak on drivers side so that's cleaned up and high temp siliconed and tightened back up. One step at a time I guess. Oil is all oil and water is still nice and clean so thumbs up there so far. I have a can of Sea Foam on hand so was going to throw that on the tank for injectors.

Seafoam is not very strong. Look for the Techron. Is your maf reading 4-6 at idle?

If the maf is 4-6, then check the O2 reading

Are you using a translator?

Don't hook up the timing wire with that one

Can't find any instructions on line. If I confirm the white timing wire is not connected, and if it is disconnect it, would I have the switches and knobs set correctly?

As I recall, the regular knobs were set just like the standard translator.
