Displacement:
327 cubic inches (5.36 Liters)
Horsepower Options:
Ranged from 250 hp (base, Powerglide) to 365 hp (L76, 4-barrel carburetor, higher compression) and 375 hp (L76 with special camshaft/carburetor, L84 fuel injection - very rare for '65, more common '63-'65).
Torque Options:
Corresponding torque figures varied with horsepower ratings, typically in the range of 350-360 lb-ft for higher output engines.
Carburetion:
Single 2-barrel (e.g., Rochester 2G for base 250hp) or single 4-barrel (e.g., Holley 4160 or Rochester Quadrajet for higher hp variants). Optional Rochester Ramjet fuel injection (L84).

Oil Capacity With Filter:
5 quarts.
Transmission Type Standard:
Muncie 4-speed manual transmission (often M20 or M21 depending on engine).
Transmission Type Optional:
Powerglide 2-speed automatic transmission. Turbo Hydra-Matic TH400 also became available for higher horsepower engines later in the '65 model year or early '66, but Powerglide was more prevalent.
Clutch Type:
Single dry plate (manual transmission).
Transmission Fluid Type:
Manual: GL-4 gear oil (e.g., SAE 80W-90). Automatic: DEXRON (or equivalent for Powerglide/TH400).
Crash Testing:
No formal crash test ratings (NHTSA/IIHS) existed in 1965. Safety features were basic by modern standards.
Braking System:
Standard front disc brakes, rear drum brakes. Optional power brakes.
Steering System:
Recirculating ball steering. Optional power steering.
Seat Belts:
Standard lap belts for driver and passenger.
Windshield:
Laminated safety glass windshield.

Every 3,000 to 4,000 miles or 6 months, whichever comes first (using appropriate classic car oil formulation).
Tune Up Interval:
Every 10,000 to 12,000 miles or annually. Includes spark plugs, points, condenser, distributor cap/rotor, ignition wires, and carburetor adjustment.
Lubrication Points:
Chassis lubrication points every 1,000 to 2,000 miles.
Engine Oil:
API SG/SH or higher, with ZDDP additive (e.g., 10W-30 or 10W-40) for flat-tappet camshaft protection. Check owner's manual for original recommendation, but modern oils with ZDDP are critical for these engines.

Chevrolet Legacy:
Chevrolet has a long history of performance and innovation in American automotive manufacturing, dating back to 1911. The Corvette, introduced in 1953, cemented its reputation as America's premier sports car.
Second Generation:
The 1963-1967 C2 Corvette, known as the 'Sting Ray,' was a complete redesign from the C1. The 1965 model year introduced significant updates, including standard four-wheel disc brakes and the potent 327ci engine with various output levels.
