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.

For the CP Carrillo BLS1138-010 pistons, a typical bore clearance of 0.0030" to 0.0035" is recommended. However, always consult with your engine builder for specific clearance requirements based on your application and operating conditions.

The CP Carrillo BLS1138-010 pistons are designed to work with standard LS ring sets. Ensure that the ring set you choose is compatible with the piston design and the intended application, particularly regarding boost levels and RPM.

The +10cc dome on the BLS1138-010 pistons contributes to a compression ratio of 11.7:1 when used with a 68cc cylinder head. Keep in mind that actual compression may vary based on factors such as head gasket thickness and combustion chamber modifications.

While the CP Carrillo BLS1138-010 pistons are designed for high-performance applications, the maximum RPM will depend on various factors including engine build quality, tuning, and overall component reliability. It's advisable to consult with your engine builder to determine a safe RPM range for your specific setup.

Typically, the CP Carrillo BLS1138-010 pistons should fit standard LS2 engine blocks without modification. However, ensure that your block is in good condition and that any necessary machining for bore clearance is performed to achieve optimal performance.
