Each piston features a 23-degree flat-top design with a -5.00 cc volume, making it well suited for engine combinations that require a controlled compression ratio and efficient combustion chamber compatibility. The kit is engineered for a 4.155-inch bore and includes piston rings for a complete installation solution.\u003cbr\u003eThe forged construction provides the strength and durability needed for high-performance street, race, and competition engines. A 1.560-inch compression height supports proper piston-to-deck and rotating assembly setup when matched with the appropriate connecting rods, crankshaft, and block configuration. The flat-top crown offers a straightforward design for builders seeking predictable compression characteristics and broad application flexibility.\u003cbr\u003eThe PTS507A3 uses 1\/16-inch, 1\/16-inch, and 3\/16-inch ring grooves for compatible compression and oil ring packages. This Wiseco-Pro Tru kit is intended for carefully measured and professionally prepared Small Block Chevy builds. Always verify bore size, compression height, ring groove specifications, piston-to-wall clearance, valve relief requirements, and final compression ratio before assembly.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrand: Wiseco-Pro Tru\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePart Number: PTS507A3\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication: Small Block Chevy\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstruction: Forged piston design for high-performance engine applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePiston Style: 23-degree flat-top crown\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBore Size: 4.155 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompression Height: 1.560 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePiston Volume: -5.00 cc\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRing Grooves: 1\/16-inch, 1\/16-inch, and 3\/16-inch\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eKit Contents: Piston and ring set\u003c\/li\u003e\u003c\/ul\u003e","brand":"WISECO-PRO TRU","offers":[{"title":"Default Title","offer_id":67644077637884,"sku":"WPTPTS507A3","price":686.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0763\/8797\/5420\/files\/WPTPTS507A3.jpg?v=1791085886","url":"https:\/\/ozkonickustomz.com\/products\/wiseco-pro-tru-pts507a3-sbc-flat-top-forged-piston-and-ring-kit-4-155-inch-bore-5cc","provider":"Ozkonic Kustomz LLC","version":"1.0","type":"link"}
