What information do I need to match these pistons to my engine?
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.
How should ring gaps be set for these pistons?
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.
Are forged pistons suitable for street engines?
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.
What is the recommended compression ratio for the BLS1123-010 pistons?
The BLS1123-010 pistons have a compression ratio of 11.6:1, which is suitable for high-performance applications. Ensure that your engine's setup, including head cc and combustion chamber design, supports this compression for optimal performance.
What is the pin size for the BLS1123-010 pistons?
The BLS1123-010 pistons use a pin size of .927 inches with a length of 2.250 inches. Make sure your connecting rods are compatible with this pin size for proper fitment.
What type of valve reliefs do the BLS1123-010 pistons have?
The BLS1123-010 pistons feature two valve reliefs. This design is intended to accommodate standard LS valve configurations, but always verify clearance with your specific cylinder head setup.
What is the recommended ring thickness for the BLS1123-010 pistons?
The BLS1123-010 pistons come with a ring thickness of 1.5mm x 1.5mm x 3.0mm. Ensure that your ring gaps are set appropriately based on your engine's application and operating conditions.
What is the weight of the BLS1123-010 pistons?
The BLS1123-010 pistons weigh 415 grams each. This weight is important for maintaining balance in your rotating assembly, so consider it when selecting other components.
