Experience a significant upgrade in power with the 131" Stroker Cylinder and Piston Kit. This kit offers a substantial displacement increase, leading to a remarkable boost in performance. Designed as a bolt-on solution, it seamlessly integrates with the stock crankcase, preserving the original engine serial numbers for authenticity.
The kit features a durable powder coat finish that perfectly matches the factory aesthetic. It includes 045" MLS (multi-layered steel) head gaskets, ensuring a reliable seal. Notably, it retains the stock engine height, allowing for easy installation without modifications.
To complete your upgrade, the kit includes a 131" Cam Cover Badge, adding a touch of style to your engine. Please note, to achieve the full 131" displacement, it must be used in conjunction with an S&S stroker flywheel.
