General Characteristics:
* Displacement: 305 cubic inches (5.0 liters)
* Configuration: Small-block V8, 90-degree
* Number of Cylinders: 8
* Bore & Stroke: Variations existed, but a common combination was around 4.00 inches bore and 3.00 inches stroke.
Performance (These figures are approximate and varied significantly by year and application):
* Horsepower: Ranged from roughly 145 hp to over 230 hp depending on the year, carburetion, fuel injection, and other factors. Lower horsepower figures are more common in earlier, less performance-oriented applications.
* Torque: Similarly varied, typically in the range of 250 lb-ft to over 300 lb-ft.
* Compression Ratio: Varied depending on the year and application. Generally in the range of 8.0:1 to 9.5:1.
Other Features (Also varied):
* Valvetrain: Pushrod OHV (Overhead Valve)
* Fuel System: Carburetion (early versions) or Throttle-Body Fuel Injection (TBI) or Multi-Port Fuel Injection (MPI) in later applications.
* Ignition: Distributor-based ignition system.
To find the precise specifications for a specific 305 engine, you need to know:
* The year of manufacture: This greatly influences the engine's specifications.
* The vehicle model it was in: Different models might have received slightly different versions of the 305.
* The engine's RPO code (if available): This is a GM internal code that often uniquely identifies the engine's specific features.
With this information, you can consult resources like GM service manuals, online automotive databases, or owner's manuals to find the exact specifications for that particular engine.
