The ICON PISTONS SBC FHR F/T Piston Set 4.155 Bore -3.7cc is designed for serious small-block Chevrolet builders focusing on forced-induction and nitrous applications. These forged pistons provide the strength and precision necessary for engines that experience boost pressures or chemical acceleration beyond naturally aspirated limits.
Engineered for high performance, these pistons feature a robust crown design and optimized ring lands that resist blowby and pinhole fractures under extreme load. The -3.7cc dish volume is calculated to work with high-compression heads, allowing tuners to maintain effective compression ratios while ensuring detonation safety margins. The 4.155-inch bore size is compatible with modern SBC block preparation, ensuring tight piston-to-wall clearance.
Ideal for turbocharged, supercharged, or nitrous-equipped 350 and 383 cubic-inch combinations, this piston set is perfect for heads-up racers and street/strip enthusiasts. Whether building a dedicated drag engine or a reliable street performer, the SBC FHR F/T set is designed to handle repeated cycles at 7,000+ RPM without fatigue.
