SBM 340 F/T Piston Set 4.070 Bore -5cc

The SBM 340 F/T Piston Set 4.070 Bore -5cc from Sportsman Racing Products is engineered for serious small-block engine builders pursuing maximum performance in Street, Strip, and competition applications. This forged piston set delivers the precision geometry and durability required for high-revving, forced-induction, and nitrous-oxide-assisted engine builds. Whether you're constructing a naturally aspirated screamer or a turbocharged power plant, this piston kit provides the foundation for reliable, repeatable horsepower across demanding operating conditions.

The 4.070-inch bore diameter and -5cc dish configuration are critical design elements that optimize compression ratio, combustion efficiency, and chamber volume for small-block platform compatibility. The -5cc dish crown reduces peak combustion pressure while improving fuel burn characteristics, particularly beneficial in boost or nitrous applications where detonation control is paramount. Sportsman Racing Products utilizes premium forged aluminum alloy construction, providing superior strength-to-weight ratios and thermal stability compared to cast alternatives, ensuring consistent ring seal and piston life even under sustained high-load operation.

This piston set is ideal for engine builders targeting small-block platforms with strict compression specifications and boost compatibility. Proper installation requires honing to achieve the correct fit, ensuring optimal performance. With this piston set, builders can expect enhanced performance and reliability in various demanding applications.
