How much horsepower does a 1970 Dodge 318 have?
The 1970 Dodge 318 small-block V8 was rated at 230 horsepower (SAE gross) from the factory. This reflects the era’s gross-rating standard, and actual output can vary with model and equipment.
Context and what the number means
In 1970, Dodge relied on the LA-series small-block 318 cubic inch V8 across a wide range of models. The 230 hp figure is a factory rating based on SAE gross measurements, which were common at the time and did not account for all accessories or emissions equipment that would be present in a car during real-world operation.
Power ratings and how they were measured
Gross vs. net horsepower
During the 1970 era, horsepower was published as SAE gross, meaning engine output was measured with minimal vehicle accessories attached. Net horsepower, which subtracts the power used by components like the alternator, water pump, and exhaust system, became more common later and typically produced lower numbers. This distinction is crucial when comparing vintage advertisements to later specifications.
Key facts about the 1970 Dodge 318 horsepower:
