In simpler terms, imagine a piston moving up and down in a cylinder. A stroker engine makes that up-and-down movement longer, thus "stroking" the engine for more power.
The modifications typically involve:
* A longer crankshaft: The heart of the modification, this component dictates the stroke length.
* Longer connecting rods: Needed to accommodate the longer crankshaft stroke.
* Possibly modified pistons: To ensure proper piston-to-cylinder clearance and prevent piston-to-valve interference.
While increased torque is a benefit, increasing the stroke length usually negatively impacts high-RPM performance and can stress other engine components. Therefore, stroker engines are generally not designed for high-revving applications, but rather for applications where strong low-end torque is desirable, such as towing, off-roading, or low-speed heavy hauling.
