This is a stock style setup, featuring a 3.580" stroke. Whether the kit is intended for stock replacement or racing, various levels of compression will allow for improved performance with emphasis on top-end power and high RPM.
This is a stroker setup featuring a 4.000" stroke and bore sizes ranging from 4.030" to 4.060". 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. Available in medium to high compression ratios.
