The 1972 Chevy 350 engine is a legendary powerhouse that has left a lasting impact on the automotive industry. Known for its reliability and performance, this engine has become a favorite among car enthusiasts and collectors alike. In this article, we will delve into the detailed specifications of the 1972 Chevy 350 engine, its configuration, engine oil specs, and service intervals.
Engine Configuration
The 1972 Chevy 350 engine features a V8 configuration, meaning it has eight cylinders arranged in a V shape. This design allows for better balance and smoother operation. The engine has a displacement of 5.7 liters or 350 cubic inches, hence the name Chevy 350. It is equipped with a cast-iron block and cylinder heads, providing durability and strength.
The compression ratio of the 1972 Chevy 350 engine is 8.5:1. This ratio determines the amount of compression that occurs inside the cylinders during the combustion process. A lower compression ratio allows for the use of regular unleaded gasoline, making it more economical to operate.
The engine is equipped with a two-barrel carburetor, which helps deliver fuel to the cylinders efficiently. It also features a points-style ignition system, which was commonly used during that era. The ignition timing is set at 8 degrees before top dead center (BTDC), ensuring optimal performance.
Engine Oil Specs & Service Intervals
Choosing the right engine oil and adhering to proper service intervals are crucial for maintaining the longevity and performance of the 1972 Chevy 350 engine. Here are the recommended engine oil specs and service intervals:
| Engine Oil Specs | Service Intervals |
