The Impala SS was uniquely fitted with a standard 3.08 gear. The limited-slip rear differential was standard (as opposed to the option G80 on Caprices) and the suspension was an inch lower. A retuned LT1 5.7l small-block V8 was standard on the Impala SS, making 260 hp and 450 Nm. The primary difference between the LT1 in the Impala and the LT1 from Corvette was that Impala engine was fitted with cast-iron cylinder heads instead of aluminum ones, and a camshaft that was designed more for low-end torque than high-end horsepower.
