Chevy LS2 Dish -13cc All std 15 deg/ L92 4.040 bore, 3.622 stroke, 6.125 rod 9.2 to 1 Comp with 68cc head (CP Bullets BLS1118-040)

You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.

Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.

Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.

The BLS1118-040 pistons are designed to achieve a compression ratio of approximately 9.2 to 1 when used with a 68cc cylinder head. However, actual compression may vary based on factors like head gasket thickness and machining tolerances.

These pistons are specifically designed for a 4.040-inch bore and a 3.622-inch stroke, making them suitable for a 371 cubic inch LS engine build.

The BLS1118-040 pistons feature two valve reliefs, which are designed to accommodate standard LS valve sizes and prevent interference with the valves during operation.

The BLS1118-040 pistons weigh 481 grams each. While lighter pistons can improve engine response and reduce reciprocating mass, it's essential to balance them with the rest of the rotating assembly for optimal performance.

Yes, proper bore clearance must be established for the BLS1118-040 pistons, along with correct ring gap settings. It's advisable to consult with your engine builder to ensure all clearances are within specifications for reliable performance.
