What is pushrod engine?

A pushrod engine is a type of internal combustion engine in which the camshaft is located inside the engine block and operated by pushrods that actuate the valves. The pushrods are typically connected to rocker arms, which then transfer the motion to the valves.

Pushrod engines are commonly found in American V8 engines, where they help reduce the engine's overall height and allow for a more compact design. They are also known for their simplicity and robustness, making them popular in many performance and racing applications.

One of the main advantages of pushrod engines is their ability to produce high levels of torque at low RPMs, making them well-suited for heavy-duty applications such as towing and hauling. However, they can be less efficient and produce more emissions compared to other engine designs such as overhead camshaft engines.

Overall, pushrod engines offer a unique balance of performance, reliability, and simplicity, making them a popular choice for a wide range of applications.
