Bogged down While In Gear And Sputtered During Acceleration

So the update is this:

New Timing chain, timing tape, and reset everything to TDC.
New Rotor, Cap, Plugs
New Carb (Mentioned Already)
3rd ignition box

Fuel Pressure is still 6.5. Did a wet compression test last night and got 170 +/-7 on all 8. Checked all lash.

Fired it up today and still same symptoms. The vacuum wants to stay at 15 and bounce +/_1 when timing is below 20Btdc. At 20 BTDC the vacuum smooths out and goes to 19. I reset the air gap in the Distributor and noticed the magnetic pickup and the plate it is attached to has some up and down play. I'm starting to think the distro is not triggering the ign box correctly when the timing is set below 20 Btdc. Also timing bounces around below 20Btdc but smoothes out after 20'

Any thoughts?
