The Bullet Piston LS1/LS2 4.065/3.622 Inch Stroke Dish -14.5 is a performance piston designed for LS1 (5.7L) and LS2 (6.0L) V8 engines. It features a 4.065-inch bore size and is intended for engines with a 3.622-inch stroke, making it suitable for custom engine builds that require an optimized combination of bore and stroke for performance gains. The dish-shaped top design, with a -14.5 cc dish volume, lowers the compression ratio, which is ideal for applications such as forced induction or nitrous, where lower compression is beneficial to prevent detonation. This piston helps improve the combustion process, air/fuel mixture efficiency, and overall engine power.
