## The Iron Duke Engine
The Iron Duke engine was designed by GM as a replacement for the Chevrolet Vega’s 140-cubic-inch (2.3-liter) inline-four engine. The Iron Duke was a more powerful and efficient engine than the Vega, and it was used in a wide range of vehicles over its 16-year production run.
The Iron Duke engine had a cast-iron block and head, and it was notable for its simplicity and durability. It was a pushrod engine with two valves per cylinder. The Iron Duke was not a particularly powerful engine, but it was reliable and fuel-efficient.
The Iron Duke engine was eventually replaced by GM’s 2.2-liter Ecotec engine in the mid-1990s. The Ecotec engine was a more modern and efficient design, and it provided better performance and fuel economy than the Iron Duke.
## Conclusion
The Iron Duke engine was a reliable and durable engine that was used in a wide range of GM vehicles from 1977 to 1993. It was a popular choice for budget-minded consumers who wanted a car that was affordable to own and operate. The Iron Duke engine is no longer in production, but it can still be found in many older GM vehicles on the road today.
