In response to 427SS65
Here is a tad more information. It appears 65 is a toss up and may have been an appearance package also. The VIN decode below states the car is an ss.
I will check the cowl in a little bit.

In 1961, the Impala SS (Super Sport) was introduced to the market. The SS badge was to become Chevrolet's signature of performance on many models, though it has often been an appearance package only. The Impala's SS package in 1961 was truly a performance package, beginning with the high-performance 348 in³ (5.7 L) engines (available with 305, 340, and 350 hp (230, 255 and 260 kW)) or the new 409 in³ (6.7 L), which was available with up to 425 hp.
The package also included upgraded tires on station wagon wheels, springs, shocks and special sintered metallic brake linings. Starting in 1962, the Impala SS could be had with any engine available in the Impala, right down to the 235 in³ 135 hp inline-6. With one exception, from this point until 1969, the SS was an appearance package only, though the heavy-duty parts and big engines could still be ordered. From 1962 on, Super Sports were limited to the hardtop coupe and convertible coupe exclusively.
The exception was the Z24 option package available in combination with the standard Z03 Super Sport package. Starting in 1967, through 1969, buyers of Z24s Impalas got cars badged as "SS427" models. The SS427 included heavy duty suspension and other performance goodies, as well as a Turbo-Jet 427 in either L36 or L72 variations. Special SS427 badging inside and out were the rule, but few were sold, since muscle car enthusiasts were looking toward big-block intermediates like the Chevelle SS396 and Plymouth Hemi Roadrunners, which were lighter and subsequently faster off the line. Interestingly, Z24 cars could be ordered without the Z03 SS package, which meant SS427 equipment but no bucket seats or center console.
The Impala SS could be identified by SS emblems on the rear fenders and trunk lid. The Impala SS became its own series (separate model rather than an option package) for 1964. In 1968, the Impala SS once more became an option package rather than having its own model. 1967 and 68 SS427s got a special domed hood and body emblems, and the '68 featured gills on the front fenders in front of the wheel opening, possible to remind people of its Corvette cousin. In 1969, the Impala SS was only available as the Z24 (SS427), coming only with a 427 in³V8 of 390 or 425 hp. This was the final year for the Impala SS until 1994.
Another plus is that the 1969 Impala SS was the last year it came with the Z24 SS 427 but the only year where front disc brakes became standard equipment, along with 15 inch wheels, which made the 69 SS427 better then its older brother the '68 SS 427 Impala. Although the 427 was replaced by the 454 Turbo-Jet V8 in 1970, the SS option was gone. Thus the 1969 Impala SS427 got the best of both worlds, which is why it is so valuable today.
