In 1971: 12 big blocks were sold with their "racer" package-the ZR2.
Since emission controls were coming on strong, the mechanical lifter alloy-headed
425-hp 454cu. in. LS6 was the last gasp of Corvette performance for quite awhile.
The ZR2 package included LS6, M22, F41, HD suspension, HD brakes, and V01 aluminum
heavy-duty radiator-in short everything the L88 had except the efficient cowl
induction hood scoop.
The L88 introduced in 1967: had a Holley 4-barrel carburetor rated at 850 cfm.
The "double-pumper" 850 had an accelerator pump at each end, and a center-pivot
float so it wouldn't suffer from fuel starvation in the corners. According to
Colvin, it was a type 4150 with mechanical secondaries with no provision for
choke.
In 1963: the first AM/FM radios were offered in the Corvette. Offered in
mid-production, the vertically mounted radio had a sliding bar, but lacked the
signal seeking feature of the "wonderbar" radio it replaced.
For the 1953 Corvette: there was 46 separate body pieces. Chevrolet staged
publicity photos showing all the body pieces laid out. As the years went on,
Corvette bodies were made of many more parts.*
