Chevy LS 365ci All 15°/L92 Bore 4.010 CH 1.300 Stroke 3.622 Rod 6.125 CR 9 Dish Head 68cc (CP Bullets BLSR1140-010)

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 BLSR1140-010 pistons, a typical bore clearance of 0.0030" to 0.0035" is recommended. However, always consult with your engine builder for specific requirements based on your application and intended use.

The BLSR1140-010 pistons come with a ring thickness of 1.2 x 1.2 x 3.0mm. As a general guideline, set the top ring gap around 0.020" to 0.022" and the second ring gap around 0.018" to 0.020", but confirm with your engine builder based on your specific build and usage.

The BLSR1140-010 pistons are designed for high-performance applications and can typically handle RPMs up to 7,500. However, reliability at higher RPMs will depend on proper machining, clearances, and tuning.

Yes, the BLSR1140-010 pistons can be used in forced induction setups. The dish design and compression ratio of 9:1 make them suitable for boost, but ensure proper tuning and fuel quality to maintain reliability.

The BLSR1140-010 pistons weigh 460 grams each. While lighter pistons can improve throttle response and reduce reciprocating mass, ensure that your engine's rotating assembly is balanced to accommodate the weight for optimal performance.
