Frequently Asked Questions
Does this manual cover both chrome-bumper and urethane-bumper C3 Corvettes?
Yes. The manual spans the full C3 production run from 1968 through 1976, addressing the earlier chrome-bumper cars (1968–1972) as well as the federally mandated urethane front bumper models introduced for 1973 and the urethane rear treatment added in 1974. Body, trim, and structural procedures reflect each year’s specific configuration.
Which Big-Block engines are fully documented?
All factory Big-Block offerings are covered, including the 427 ci variants (L88, LS5, LS6, and LS7 ratings) available through 1970 and the 454 ci LS4 that carried Big-Block buyers through 1974. Rebuild specifications, torque values, and carburetor service procedures are included for each variant.
Are the Muncie close-ratio and rock-crusher transmissions covered?
All three Muncie 4-speed units are covered: the M20 wide-ratio, the M21 close-ratio, and the heavy-duty M22 “Rock Crusher” used behind high-output Big-Block engines. Full rebuild, synchronizer service, and shift linkage adjustment procedures are included alongside coverage of the Turbo Hydra-Matic 400 automatic.
