Engine Wear:
High-performance engines can experience accelerated wear on piston rings, bearings, and valve train components if not properly maintained or if subjected to excessive stress. Carburetor and ignition system tuning are critical.
Suspension Wear:
Bushings, ball joints, and tie rod ends can wear over time, affecting handling and alignment. The independent rear suspension requires periodic inspection.
Electrical Gremlins:
Aging wiring harnesses, corroded connections, and failing components (e.g., voltage regulator, ignition switch) can lead to intermittent electrical issues.
Fiberglass Body Issues:
Cracks, delamination, and stress fractures can occur in the fiberglass body panels, particularly around high-stress areas or after impacts. Gelcoat issues like cracking or fading are also common.
Parts Concern:
While many common parts are reproduced, specific performance-oriented engine components or unique trim pieces can be rare and expensive.
Chevrolet Heritage:
Chevrolet, a division of General Motors, has a long history of producing reliable and performance-oriented vehicles, from the economical to the aspirational.
Corvette Lineage:
The C2 generation Corvette (1963-1967) introduced iconic styling like the Sting Ray and independent rear suspension. The 1964 model year saw refinements to the chassis and engine options, with the introduction of larger displacement engines becoming more prominent.
Production Years C2:
1963-1967
1964 Production Highlights:
Introduction of side-mounted exhaust pipes as an option, minor interior and exterior trim updates, continued popularity of the big-block engines as they became more refined.
427 Engine Debut:
The 427 V8 engine (L72) was officially introduced in the Corvette for the 1966 model year. If this manual references a '1964 Corvette 427', it likely refers to a manual that covers modifications or is broadly inclusive of major performance variants, or possibly a very early, limited availability of a precursor engine or a specific package that evolved into the L72. The more commonly associated '427' for 1964 would be the 396ci (L37 or L78) big-block, which was often referred to colloquially as a '427' due to its size and presence. This manual's coverage of '427' for 1964 might be a slight historical nuance or cover a very specific, less common configuration. A true L72 427 was not standard for 1964.
Automotive Awards:
The C2 Corvette, particularly performance variants, is widely recognized as an automotive icon and a benchmark for American sports car design and performance in its era. It consistently ranked high in enthusiast polls and performance reviews of its time.
Performance Ratings:
Contemporary road tests and reviews frequently praised the Corvette's acceleration, handling (especially with upgraded suspension and tires), and braking capabilities, establishing it as a true supercar of its generation.
