The third-generation Corvette, patterned after the Mako Shark II concept car, was introduced for the 1968 model year and was in production until 1982. C3 coupes featured the first use of T-top removable roof panels. It introduced monikers that were later revived, such as LT-1, ZR-1, Z07, and Collector Edition. In 1978, Corvette's 25th anniversary was celebrated with a two-tone Silver Anniversary Edition and an Indy Pace Car replica edition of the C3. This was also the first time that a Corvette was used as a Pace Car for the Indianapolis 500.[42] Engines and chassis components were mostly carried over from the C2, but the body and interior were new. The 350 cu in (5.7 L) engine replaced the old 327 cu in (5.36 L) as the base engine in 1969, but power remained at 300 hp (224 kW). 1969 was the only year for a C3 to optionally offer either a factory-installed side exhaust or a normal rear exit with chrome tips. The all-aluminum ZL1 engine was also new for 1969; the special big-block engine was listed at 430 hp (321 kW), but was reported to produce 560 hp (418 kW) and propelled a ZL1 through the 1⁄4 mile (0.40 km) in 10.89 seconds.[43] There was an extended production run for the 1969 model year due to a lengthy labor strike, which meant sales were down on the 1970 models, to 17, 316.[44] 1970 small-block power peaked with the optional high compression, high-revving LT-1 that produced 370 hp (276 kW). The 427 big-block was enlarged to 454 cu in (7.44 L) with a 390 hp (291 kW) rating. The ZR-1 special package was an option available on the 1970 through 1972 model years, and included the LT-1 engine combined with special racing equipment. Only 53 ZR-1's were built.[45] In 1971, to accommodate regular low-lead fuel with lower anti-knock properties, the engine compression ratios were lowered which resulted in reduced power ratings. The power rating for the 350 cu in (5.7 L) L48 base engine decreased from 300 to 270 horsepower and the optional special high-performance LT1
