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 compression ratio can I expect with the BLS1136-005 pistons?
The BLS1136-005 pistons provide a compression ratio of 10.6:1 when used with a 68cc head. However, actual compression may vary based on factors such as head gasket thickness and combustion chamber modifications.
What are the recommended bore and stroke specifications for these pistons?
These pistons are designed for a 4.070-inch bore and a 3.622-inch stroke, making them suitable for a 377 cubic inch LS engine build.
What is the pin size for the BLS1136-005 pistons?
The BLS1136-005 pistons feature a pin size of .927 inches with a length of 2.250 inches. Ensure your conrods are compatible with these specifications.
What is the weight of the BLS1136-005 pistons?
Each BLS1136-005 piston weighs 492 grams. This weight should be considered when balancing the rotating assembly for optimal performance.
Do the BLS1136-005 pistons have valve reliefs?
Yes, the BLS1136-005 pistons come with two valve reliefs, which are essential for clearance with the LS engine's valves during operation.
