Each piston features a 3.800-inch bore diameter and a 4-inch stroke, optimized for durability and efficiency. The set includes pistons with a 6.125-inch connecting rod length and a .927-inch wrist pin diameter, ensuring accurate fitment and reliable operation. Coated with phosphate and Grafal for enhanced wear resistance and corrosion protection, these pistons are engineered to withstand demanding engine conditions. The compression ratio is approximately 9.4:1, making them suitable for a variety of performance builds without compromising drivability. Weighing around 365 grams per piston, this set offers a balanced combination of strength and lightweight design, vital for high-revving engines and optimized power output. The pistons are not carb-approved and require acknowledgment of carb compliance, making them suitable for specific racing and performance applications. Designed with a 16cc dish volume, these pistons contribute to achieving the desired compression ratio and combustion efficiency. The set is crafted by Mahle, a trusted name in automotive engineering, ensuring quality and consistency. Please note that these pistons are not approved for use with carbureted engines without proper acknowledgment and are intended for professional installation in performance-oriented vehicles. The set is shipped as a complete package of eight pistons, ideal for rebuilding or upgrading GM LS engines for racing or high-performance street use. Their robust construction and coatings help prolong engine life and maintain optimal performance over time.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned for GM LS engines with 363 cubic inches displacement\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e3.800-inch bore diameter for precise fit and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e4-inch stroke length for high torque output\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e6.125-inch connecting rod length for durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e.927-inch wrist pin diameter for secure piston pin fit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePhosphate and Grafal coatings for enhanced wear and corrosion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApproximately 9.4:1 compression ratio for versatile performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLightweight at around 365 grams per piston for high-revving operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNot carb-approved; requires acknowledgment for carb compliance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSet of 8 pistons, suitable for professional engine rebuilds and upgrades\u003c\/li\u003e\u003c\/ul\u003e","brand":"Mahle","offers":[{"title":"Default Title","offer_id":46977975484615,"sku":"mhl930219600","price":927.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/2277\/5751\/files\/3ca5314bdfcae5e6e1828e5c16d70b35.jpg?v=1786417321","url":"https:\/\/mainstreeteshop.com\/products\/mahle-ms-piston-set-for-gm-ls-363ci-with-3-800-inch-bore-and-4-inch-stroke","provider":"MAIN STREET ESHOP","version":"1.0","type":"link"}
