Hotrodrobert,
Good to know.
I assume the 1bbl on your 70 Nova was an MV?
Mine were the earlier B/BC/BV carbs.
Seems you saw the same trend - the 1bbl, whether BV or MV, is not as good on gas as the later design 2bbl (or 4bbl) carbs.
I thought this might have improved with the MV design but looks like it didn't.
