This advanced metallurgy permits tighter bore clearances, which help minimize noise on cold engine start-up. These pistons are the ideal choice for street performance applications and late-model replacement.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003e More Sealed Power hypereutectics benefits:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e Higher strength than cast or forged at operating temperature\u003c\/li\u003e \u003cli\u003eFinely dispersed silicon particles provide a highly resistant wear surface and reduces scuffing\u003c\/li\u003e \u003cli\u003eLower material growth allows pistons to be fit tighter, improving cylinder sealing for less blow-by and more power\u003c\/li\u003e \u003cli\u003eHigh silicon content allows elimination of groove inserts in certain applications\u003c\/li\u003e \u003cli\u003eDesigned to retain standard ring gaps in the top groove\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003e Piston Specifications :\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eCID: 407\u003c\/li\u003e \u003cli\u003eBore: 4.155\u003c\/li\u003e \u003cli\u003eStroke: 3.750\u003c\/li\u003e \u003cli\u003eRod Length: 5.565\u003c\/li\u003e \u003cli\u003eCompression Height: 1.560\u003c\/li\u003e \u003cli\u003eCompression Ratio with 64cc chamber volume: 10.14\u003c\/li\u003e \u003cli\u003eCompression Ratio with 72cc chamber volume: 9.40\u003c\/li\u003e \u003cli\u003eCompression Ratio with 76cc chamber volume: 9.08\u003c\/li\u003e \u003cli\u003eDome Volume: -12.5cc\u003c\/li\u003e \u003cli\u003ePin Type: Press pin\u003c\/li\u003e \u003cli\u003eRecommended Ring Set: Moly - SPE243K 030, File Fit SPR5879 035\u003c\/li\u003e \u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Speed Pro","offers":[{"title":"Default Title","offer_id":44555872370999,"sku":"SPH601P030","price":430.7,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/207816.jpg?v=1780383611","url":"https:\/\/enginemaster.com.au\/products\/speed-pro-sph601p030-400-ci-sb-chev-dish-top-hypereutectic","provider":"Engine Master","version":"1.0","type":"link"}
