The BB is positioned at 5 degrees before TDC on a 216 flywheel and 2 degrees after on a later 235 which alone may be enough difference to make it not want to fire. Secondly the BB shows up in the window both when #1 is at TDC and also #6 so being 180 degrees out is also a possibility. Try this procedure to set timing for startup:
