Pontiac V8 Dished Piston Set 4.160 Bore -14cc

The Pontiac V8 Dished Piston Set 4.160 Bore -14cc from ICON Pistons is designed for automotive enthusiasts and professionals focused on building high-performance Pontiac V8 engines. These dished pistons are crucial for engine builders aiming for specific compression ratios, especially in applications involving forced induction or nitrous, where managing combustion chamber volume is essential.

This piston set features a -14cc dished design that effectively reduces combustion chamber volume, enabling builders to increase the compression ratio without the need for enlarging the bore diameter or milling the block. ICON Pistons utilizes premium alloy materials, ensuring optimized ring grooves and pin boss geometry for enhanced structural integrity, which is vital for high-RPM operation and thermal stability.

Ideal for Pontiac 350, 389, 400, and 455 big-block V8 engine rebuilds, this piston set is perfect for those looking to fine-tune compression for optimal fuel octane utilization. Proper installation requires careful consideration of deck height, rod length, and ring gap spacing, which are critical for achieving reliable performance in both street and racing applications.
