Pont. 400 Dished Piston Set 4.150 Bore -17cc

The KB Performance Pontiac 400 Dished Piston Set 4.150 Bore -17cc is a specialized piston solution designed for Pontiac V8 engine builds that require a reduction in compression ratios. This eight-piston set is ideal for builders looking to optimize performance while maintaining reliability in both street and competition applications.

Crafted from hypereutectic alloy, these pistons offer enhanced thermal stability and reduced expansion-related clearance issues during operation. The -17 cubic centimeter dish cavity effectively lowers compression, making it suitable for forced-induction setups or lower-octane pump fuel. Each piston features a 4.150-inch bore diameter and a ring groove configuration of 5/64 x 5/64 x 3/16 inch, ensuring optimal performance in high-displacement Pontiac V8 applications.

Engine builders restoring classic Pontiac models or enhancing performance packages will find KB Performance pistons to be a reliable choice. The design incorporates proven load distribution and pin boss reinforcement, translating to extended service life across various duty cycles, including street, strip, and marine applications.
