1971 Facts

. The 1971 Corvette was one of the least changed in appearence. A labor dispute in May 1969 caused the 1969 production to run long, shortening normal 1970 production over 4 months. Chevy then treated the 1971 as an extention of the 1970. Plus GM directed its division to reduce octane requierments in 1971 engines , an effort which carried a higher priority than appearence changes.

. With the exception of RPO LS6, 1971 engines were detuned varients of the 1970 engines. GM's intention in reducing octane requirements to 91 in 1971 was to give oil companies time to phase in unleaded fuels which needed a catalytic converter still four years away.

.The 454ci LS6 engine with 425hp was designed to operate on low-lead fuel, but a comparable engine was not available in 1970, so it won the horespower race for the two years despite it's lower octane appetite. It featured aluminum heads and could be combined with an automatic transmission, although not when combined with the ZR2 package.

. One visible clue to a 1971's outward appearence is the amber parking light lenses, although very early production had clear lenses.

. The 1971 Corvette was the last to use fiber-optics light monitoring system. It's thought the cost savings permitted inclusion of the optional anti-theft alarm system as a standard equipment the following year.
