Wiseco K0070A155 Small Block Chevy Turbo/Supercharger Dish Piston - 23-Degree Kit

The Wiseco K0070A155 is a forged piston kit designed for Small Block Chevrolet engines built to stock stroke dimensions with forced induction applications in mind. Featuring a 23-degree valve angle dish top design, these pistons are engineered to work with traditional 23-degree small block Chevy cylinder heads while accommodating the lower compression ratios ideal for turbocharged and supercharged builds.

Wiseco pistons are cold-forged from 2618 aluminum alloy, delivering exceptional strength-to-weight ratios and the thermal resilience required to withstand the elevated cylinder pressures generated by forced induction. The dish dome profile reduces static compression ratio, helping tuners achieve the target boost-friendly compression needed for reliable power output under boost.

Key Features:

• Forged 2618 aluminum alloy construction for superior strength and durability
• 23-degree dish top profile matched to SBC 23-degree cylinder head valve angles
• Optimized for turbocharger and supercharger applications
• Built to stock stroke dimensions for straightforward assembly
• ArmorGlide skirt coating reduces friction and improves break-in
• Precision CNC machining for consistent tolerances and ring seal
• Includes rings, wrist pins, and retaining clips

The Wiseco K0070A155 piston kit is an excellent choice for performance builders looking to assemble a reliable, boost-ready Small Block Chevy engine using factory stroke measurements with proven Wiseco forged piston quality.
