<P> The Impala SS was 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 5.7 - liter ( 350 cu in ) small - block V8 was standard on the Impala SS , making 260 hp ( 194 kW ; 264 PS ) and 330 lb ⋅ ft ( 447 N ⋅ m ) of torque ( retuned from the prototype 's 300 hp ( 224 kW ; 304 PS ) rating ) . The primary difference between the LT1 in the Impala and the LT1 that was in the Corvette and Camaro was that the 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 . Another difference was that the block casting for the Impala LT1 had two - bolt main bearing caps while the casting used for the Corvette LT1 had four - bolt main bearing caps . The transmission was the 4L60E , which was an electronically controlled version of the previously hydraulically controlled 4L60 . However , the transmission was not beefed up for the power of the LT1 , and transmission failures after 100,000 miles ( 160,000 km ) were commonplace . </P>
