These pistons feature a 4.040-inch bore and a 3.4-inch stroke, optimized for precise engine build and durability. The set includes eight pistons with a .927-inch pin diameter, and each piston is engineered with a compression ratio of approximately 10.1:1, ensuring efficient power output and fuel economy. Constructed with advanced coatings of phosphate and Grafal, these pistons provide excellent wear resistance and corrosion protection, extending the engine's lifespan and maintaining optimal performance over time. The pistons have a negative deck height of -6.5cc, contributing to achieving desired compression levels and engine efficiency. The set's total weight is approximately 405 grams per piston, balancing strength and weight for reliable operation at high RPMs and heavy loads. Designed specifically for Ford Small Block engines, these pistons are not carburetor approved but require carb acknowledgment during installation, making them suitable for specialized automotive builds. These pistons are ideal for enthusiasts and professional mechanics seeking durable and high-quality components for custom engine projects, race engines, or performance upgrades.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBore: 4.040 inches for precise fit and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStroke: 3.4 inches optimized for Ford Small Block engines\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRod Length: 5.4 inches for balanced engine dynamics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePin Diameter: .927 inches for secure piston-to-connecting rod connection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompression Ratio: Approximately 10.1:1 for efficient power\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCoatings: Phosphate and Grafal for wear resistance and corrosion protection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eWeight: Approximately 405 grams per piston for durability and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for 349 CID Ford Small Block engines\u003c\/li\u003e\u003c\/ul\u003e","brand":"Mahle","offers":[{"title":"Default Title","offer_id":46982367215815,"sku":"mhl930244740","price":826.97,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/2277\/5751\/files\/7083ee9ccb19e2e8281799a806530fdc_266e0829-e22f-4e14-969c-5358567b25b1.jpg?v=1786493188","url":"https:\/\/mainstreeteshop.com\/products\/mahle-ms-piston-set-for-ford-small-block-349-cid-4-040-in-bore-3-4-in-stroke-5-4-in-rod-part-number-mhl930244740","provider":"MAIN STREET ESHOP","version":"1.0","type":"link"}
