I have here an article from Australian Hot Rod Nov 1966.
It shows a deluxe set-up on a red motor.
You can see in pic how the long thin casting
with "norman" cast into it, is the intake manifold.
It comes out from 'under' the unit to the
'elbow with the flange', which can be swiveled to level
the carby when the unit is swiveled to tension the drive belts.
Your unit looks to have a custom manifold, which allows the carbs
to sit 'over' the unit, which must have been turned upside down
in a custom instillation.
