By far the most popular interior features of any year of the SS427 are undoubtedly the round "pod" type of instrumentation used in the 1967 model year. The type of cluster shown in the pictures above is the most prominently mentioned reason for an owner preferring the 1967 cars to the other years.
The interior of the 1967 Impala SS427 received no special "SS427" ornamentation, but instead retained the "Super Sport" emblems above the glove box and on the steering wheel. Shown above and to the left is the optional wood grained plastic steering wheel (RPO N-34). As you can see, when ordered on an SS427, this type of wheel retained its Chevrolet bowtie horn button cap as opposed to receiving any type of special "SS427" decoration. The picture above and to the right shows how the standard wheel in an SS427 would appear. This wheel is from a 396 powered 1967 Super Sport convertible.
Also shown in the pictures above is the optional "Special Instrumentation Package" (RPO-U14) that was very well laid out and featured the afforementioned three large round gauges that included a tachometer, speedometer and clock. It also included four smaller gauges, two on either side, that consisted of the gas gauge, ammeter, water temperature and oil pressure indicators. The picture to the far left shows the tachometer that redlines at 5,500 R.P.M., which is the correct setup for the 385 horsepower 427 V-8s.
