Hello ACOArch - Yep!... "cold air" vents in the footwells. My car has them, though the ductwork runs through the engine compartment, where the "cold air" gets nice and toasty before it actually gets to the footwells. That, too, will be changed by re-routing the ducts through the wheel arches (where they were subsequently placed in later models).
Emmanuel will be doing bonnet modifications to facilitate the flow of air through the engine compartment ( therefore eliminating back pressure, hopefully improving air flow through the radiator and reducing hot air flowing into the passenger compartment). Also we hope to fashion a subtile way to bring denser, cold air to the Carb. Making the decorative side vents actually function will be a part of the endeavor to pull air out of the engine compartment.
An odd thing about CFX29 (my car) - all the dated engine parts and transmission were from 1967, just late enough to have been 1968 model year parts. Yet my car 'left the factory' in 1969 and was shipped to Montreal, Canada (subsequently shipped to the USA as a 1970 Ford). Was it fabricated in England earlier, then held up by the Strikes in Italy? Or were the engine and transmission ordered in 1967, then held in stock? Might it have been for another purpose (an AC 428 big block?). The block is a "Police Interceptor" reinforced block with a scratched letter "C" - the same block used on Shelby GT 500 and "Cobra Jet" mustangs. The heads are not "cobra Jet", though the original Intake manifold could be.
We ARE having fun. It's a real benefit that parts (original and reproduction) are available a fairly plentiful. The original "Cobra" guys are still alive and still working. Excellent!
