with large "SS427" emblems on the front grille and rear trim. None of these cars had the name "Impala" anywhere on the body or interior, and Chevrolet often marketed them as the "Chevrolet SS427," sans the "Impala" name. The Z24 package also included a special hood with fake chrome-plated intake. Only about 400 Super Sports had a six-cylinder engine from 1967 to 1968, in 1969, or L72 () from 1968 to 1969. Special SS427 badging, inside and out, was the rule, but few were sold, since muscle car enthusiasts were seeking big-block intermediates, such as the Chevelle SS396 and Plymouth Road Runner. In 1968 as Caprice sales escalated, those of the Impala Super Sport suffered a decline. Much of this drop in sales was no doubt due to the availability of big-block engines in the mid-sized (and lighter) Chevelle, and even Novas could be special-ordered with the 396 engine with the new-for-1968 body. No longer a separate series, the Super Sport was a mere $179 option package (Regular Production Option Z03) for the two Impala coupes and the convertible. Only 38,210 Impalas were so-equipped, including 1,778 with the Z24 package, which was carried over from 1967. In 1968 only, SS427s could be ordered without the Z03 SS package, which meant SS427 equipment but no bucket seats, SS door panels, or center console. The Z03 Impala SS could be identified by "Impala Super Sport" badges on the front grille, rear fenders and trunk lid. Z24-optioned cars included "SS427" emblems to replace the "Impala Super Sport" badges, a special layered "pancake" hood, and three "gills" mounted on the front fender aft of the wheel well à la Corvette Stingray. In 1969, the Impala SS was available only as the Z24 (SS427), coming exclusively with a V8 of , , or . This was the final year for the Impala SS until 1994. Unlike the previous two years, the 1969s finally got "Impala" script on the front fenders and interior. The 1969 Impala SS had no distinctive SS badging inside the car except for an "SS" logo the steering wheel (again, there was no Z03 offered that year). Like the 1968s, the Z24 could be ordered on the Impala convertible, Sport Coupe, or Custom Coupe. 1969 was the last year that the Impala SS was offered with the Z24 package, but the only year in which front disc brakes and wheels were standard;
