what engine is in a 1996 impala ss
Chevrolet Impala 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.[citation needed]
