..........by use of the old fashioned road draft tube.
Was there a good reason for this, from an engineering viewpoint?

Re: Lack of PCV on L88...............
No PCV system only applies to the 1967 model year L-88. Remember, it was a racing engine - not meant for road use. In fact, the lack of a PCV system made it illegal to register for road use anywhere in the United States. PCV systems became a federal requirment for road use beginning in '63 and 1961 in California.
Most racing engines of that era had liberal crankcase vents and most sanctioning organizations required that the crankcase be vented to a "catch can" to contain any oil that was expelled from the system, so the draft tube would have had to be replaced with a catch can system.
The '68 and '69 L-88 had a PCV system.
Chevrolet provided a basic racing engine,suspension, and brakes that could be installed at St. Louis, driven off the line, and through the transportation system to the dealer. It was up to the buyer to prep the car for racing by adding appropriate safety equipment, racing tires, and a racing exhaust system.
If you bought a Cobra you could get all the racing goodies installed by Carroll Shelby at the plant.
