Not 100% sure of the difference, because I don't know the emissions requirements for the original Cobras here in CA, but I used to own a 1966 Corvette Convertible with a 427ci/425hp (solid lifter) engine. There were two 427's offered by GM in 1966. The other 427 offered was a 427ci/390hp (hydraulic lifter). While the 390hp Corvettes had smog (air) pumps in 1966, the 425hp Corvettes were smog (air) pump exempt and only had to have a PCV system.
So, maybe the 1966 Cobras here in CA also had the smog (air) pump exemption, similar to the 1966 Corvette 427ci/425hp cars. Just my guess.
