Where is the camshaft typically located in a "pushrod" engine?

In a pushrod engine, the camshaft is typically located in the cylinder block. This arrangement allows the use of pushrods to transfer the motion from the camshaft, through the lifters and pushrods, to the rocker arms located in the cylinder head. The configuration of the camshaft in the block is important because it provides a simpler design with fewer components, which can lead to benefits such as reduced weight and complexity compared to overhead camshaft (OHC) designs.

In contrast, placing the camshaft in the cylinder head allows for different configurations such as dual overhead cam (DOHC), which can improve performance by enabling more direct control over the valves. However, in a traditional pushrod layout, keeping the camshaft in the block is a crucial aspect of the engine’s design and functionality.
