The Bullet Piston LS1/LS2 4.030/3.622 Inch Stroke Dish -13 is a performance piston designed for GM's LS-series V8 engines, specifically the LS1 (5.7L) and LS2 (6.0L). It features a 4.030-inch bore size and is intended for engines with a 3.622-inch stroke, offering a unique combination of bore and stroke for optimizing engine displacement and performance. The dish-shaped top with a -13 cc dish volume helps reduce the overall compression ratio, making it ideal for high-performance applications where managing compression and combustion dynamics is crucial, such as in forced induction or high-revving builds.
