The Pontiac V8 FT Piston Set 4.165 Bore -.430cc from ICON Pistons is designed for serious engine builders and Pontiac V8 enthusiasts engaged in high-performance modifications. This piston set is essential for applications requiring a specific bore diameter and compression cavity volume, making it suitable for stroker builds, vintage muscle car restorations, and race engine assembly.
Manufactured using premium aluminum alloy forging technology, this piston set offers a superior strength-to-weight ratio and thermal conductivity compared to cast alternatives. The 4.165-inch bore diameter is designed to accommodate precision ring grooves and piston pin bosses, ensuring durability under high-RPM operation and boost pressures typical in modern forced-induction Pontiac conversions. The -.430cc dish cavity is engineered to provide controlled compression characteristics, optimizing combustion chamber geometry for effective tuning of fuel octane requirements.
Ideal for those rebuilding classic Pontiac engines such as the 400, 421, or 455, this piston set is also suitable for modern stroker combinations. Each piston is machined to exacting tolerances, with skirt profiles optimized for reduced friction and minimized blow-by, enhancing overall engine performance and longevity.
