This is a stroker setup featuring a 4.250" stroke and bore sizes ranging from 4.250" (standard) to 4.375". Because of the longer stroke and "square" configuration, these kits are a great balance between low-end torque and high-end power and RPM, making them extremely versatile, as well as more powerful than stock. They are great in any environment ranging from street to drag racing applications.
