I've also been toying with this same idea, and the filtration part is
relativly simple.
 By using a flat air filter from (I believe) one of the Sabaru models, it
could be placed in a fabricated "box" facing the air stream with the
tubing exiting the rear. 
 My big hang up is the carb calibration. 
 The fuel/air calibration now has an added item in the equation. Ie. the
velocity of the air entering the carb throat is a function of road speed,
as well as engine speed. The result would be that the mixture that is
right at, say, 4000 RPM in 1st gear is not the same as 4000 RPM in 4th. 
I doubt very seriously that the SU's abilitiy to compensate for varying
conditions will stretch to that extreme.

 My sentiments exactly!. So the "ram tuning" will get passed over in
favor of the Rover V-8 hanging on the engine stand (with various and
sundry parts on order or in boxes)
