As further evidence that this does work, take a look at
        motorcycles.  These are some of the
        highest power per cubic inch engines in the world and the
        carburetors are coupled directly to the
        intake ports on the heads.

   Paul, and Hennie,
   The Motorcycles using the carbs almost bolted to the head, (actually
   rubber mounted in circular rings) are all designed for max power at what
   we would consider surealistic RPM. Even the street middleweight
   performance bikes are redlining at near (or beyond) 14,000! The super
   short intake is the correct length for those RPM's. The LeMans engine
   still has one of the highest outputs for a NA engines and the short
   length on the super trick variable length manifold is about 18".  Proper
   tuning depends on your intended max RPM. If you are willing to lose the
   benifit of tuned intake you can make the manifold as short as you wish,
   but HP will suffer and BSFC even more so.

While a carb probably damps that organ pipe effect, doesn't the
configuration of the airbox (plenum) on the cold side of the carb come
into play?  So, the hot side of the manifold is very short, the cold
side is often quite a bit longer...
