Put the old "Edel-Brick" on to test for non-carb problems, and lo and behold it actually runs pretty well, so I am back to "it IS the carb". Edelbricks are easy to tweak, I stepped up 2 stages rich in power mode with a rod change, and fattened up the idle mixture and darned if the old brick isn't in a reasonable state of tune for the new motor. I was getting pretty desperate to just get the thing out of the garage and on the road since I have to test every major system on the car, so I'm glad the Edelbrick is there as a backup. Now I can take my time trying to debug the Holley. I'll take everyones advice and get rid of the sight glass and have another go.
