Good point ... not sure that I was aware of it until I saw

The 'A' already has the 'snout' ... there is an 'air duct'
(metal tube) that penetrates the radiator support on both
sides ... on both sides a hose runs from the grille area to
the front side of the radiator support ... on the right hand side
a hose runs from the rear of the radiator support to the heater.
IOW, the 'A' does have a 'cold air hose' for the carbies, but it
stops at the radiator support. My thought was to attach a
hose to the rear of the radiator support (the flange is already
there) and extend it to a 'cold air box' fitted to the carbies.
Do you think the additonal hose and 'cold air box' will provide a
measurable improvement in performance? ... or is the existing
'cold air hose' adequate?
