In 1968 due to the increased emphasis on luxury the Impala SS reverted back to an option package (RPO Z03 at $179) and was ordered on only 38210 out of 710900 Impalas. (Impala SS engine options included the 250ci 155hp I-6 307ci 200hp V-8 327ci 4 bbl 250hp V-8 327ci 4 bbl 275hp V-8 396ci 4 bbl 325 V-8 427ci 4 bbl 385hp V-8 and the 427ci 4 bbl 425hp V-8.) The SS option was now available on three models the convertible the Sport Coupe (hardtop coupe) and the Custom Coupe. Both the 396 and 427 engines continued despite continued falling sales. The SS 427 package continued as RPO Z24 with the 385hp 427ci engine but a 425hp 427ci was optionally available. This was the L72 427 with the big port heads aluminum intake and Holley 780 cfm combination 11.0:1 compression and a solid-lifter camshaft. In addition to the minor facelift on the 1968 Impala new styling features included hideaway windshield wipers and front and rear side-mounted marker lights which were federally mandated. On the rear the Impala returned to the three-per-side taillight motif but these were mounted within the new bumper. Prices ranged from $2846-$3197. Weights were approximately 3250-3940 lbs.
