Variant 1:
327 cubic inch (5.4L) Small-Block V8. Horsepower ratings: 300 hp (base), 350 hp (L46), 365 hp (L79), 375 hp (L79 with specific options).
Variant 2:
427 cubic inch (7.0L) Big-Block V8. Horsepower ratings: 400 hp (L71 - Tri-Power carburetors), 430 hp (L88 - high-performance, race-oriented, low vacuum secondary operation, gross rating), 430 hp (L89 - aluminum heads, gross rating).
Torque 427:
427 CID engines typically produced over 460 lb-ft of torque (gross).
Carburetion:
Single 4-barrel Rochester carburetor (327 engines), or Triple 2-barrel Rochester carburetors (3x2 'Tri-Power') on the L71 427. L88/L89 engines used a single 780 cfm Holley carburetor.
System:
Breaker-point ignition system with single ignition coil. High-energy ignition (HEI) was not yet standard.
Radiator:
Heavy-duty radiator, especially for high-performance 427 engines, with a shroud for improved airflow.
Oil Change:
Recommended every 3,000 miles or 6 months. However, for classic car use, checking oil level and condition more frequently is advised. Vintage engines may benefit from shorter intervals.
Tune Up:
Spark plug replacement, ignition timing adjustment, and carburetor adjustment typically recommended every 10,000-15,000 miles, or as needed based on performance.
Coolant Flush:
Every 2 years or 30,000 miles, using a 50/50 mix of coolant and distilled water. Check for corrosion inhibitors suitable for older cooling systems.
Engine Oil:
API SF/CD or SG rated oil, with viscosity grade like 10W-30 or 10W-40.ZDDP additive is highly recommended for flat-tappet camshaft protection.
Brake Fluid:
DOT 3 or DOT 4 glycol-based brake fluid. It's crucial to use fresh fluid due to its hygroscopic nature.
Coolant:
Ethylene glycol-based coolant. A 50/50 mix with distilled water is standard. Some classic car enthusiasts prefer specific coolants with rust inhibitors suitable for older systems.
Carburetor Leaks:
Older carburetors (especially Rochester Quadrajets and Holley units) can be prone to fuel leaks from deteriorated gaskets and seals.
Ignition Points:
Breaker points require regular cleaning and adjustment to maintain proper ignition timing.
Fiberglass Cracks:
Corvette fiberglass bodies can develop stress cracks, particularly around mounting points or high-stress areas, requiring specialized repair.
Rubber Components:
Age-related deterioration of rubber hoses, seals, and bushings (suspension, steering, body mounts) is common and requires replacement.
Cooling System:
Original radiators and cooling system components can degrade, leading to leaks or inefficient cooling, especially with powerful engines.
Legacy:
Chevrolet's flagship sports car, established as a performance icon since its introduction in 1953.
C2 Generation:
The 1967 model year was the final year of the C2 'Sting Ray' generation, known for its distinctive styling and improved performance.
Design Influence:
Introduced significant design refinements over previous C2 years, including functional hood extractors and side-mount exhaust options.
Production Volume 1967:
Approximately 14,437 Corvettes produced in 1967.
Key Options 1967:
The 427 Big Block engine (L71, L88, L89) was a major performance option for 1967. Power steering, air conditioning, and automatic transmission were also popular.
