{"product_id":"forged-dome-top-piston-kit-4-060-inch-bore","title":"Forged Dome-Top Piston Kit, 4.060-Inch Bore","description":"The SRP 140350 piston kit is an advanced, lightweight solution engineered for Small Block Chevy engines requiring a 4.060-inch bore and 3.750-inch stroke. Built from high-silicon 2618 aluminum alloy, these FSR-forged pistons offer superior strength while being significantly lighter than traditional designs to support reliable performance in both street and strip environments. The domes are CNC-machined with radiused valve reliefs to promote optimum flame travel.\n\nTechnical specifications include a 1.125-inch compression height and a 7.00cc dome volume. These pistons are designed specifically for use with 23-degree cylinder heads. The kit arrives with pin fitting, double spiro locks, oil rail supports, and 0.927-inch diameter wrist pins (130 grams each). Please note that the CNC-machined ring grooves are sized for 1\/16, 1\/16, and 3\/16-inch ring packages, which are sold separately.\n\nCompression ratios vary based on cylinder head chamber volume, achieving 14.2:1 with 58cc heads, 13.0:1 with 64cc heads, and 12.0:1 with 70cc heads.","brand":"SRP","offers":[{"title":"Default Title","offer_id":52686346912056,"sku":"140350","price":734.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687852290.jpg?v=1784872129","url":"https:\/\/store.motormia.co\/products\/forged-dome-top-piston-kit-4-060-inch-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
