Product Details

When you're building a serious performance engine, the pistons are a critical component that needs to handle a lot of stress. This set from Mahle is designed for high-output 350 cubic inch Chevrolet LS engines, featuring a 4.065-inch bore and a 3.370-inch stroke. You'll receive a complete set of 8 pistons, ready to be installed in your build.

These pistons are forged, which means they're built from a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for applications where you're pushing the limits. They have a 1.200-inch compression height and come with a 0.927-inch pin. The valve reliefs are designed with a 12.7cc volume, accommodating significant valve lift and duration. Because these are made to order, they offer a unique opportunity to get precisely what your custom build needs.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal installation and performance, always refer to the manufacturer's detailed specifications and recommended assembly procedures.
