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 BH574-950-020 pistons?
The BH574-950-020 pistons are designed for a compression ratio of 9.5:1 when used with the 5.7 Eagle Hemi head. Ensure that your engine's setup, including head cc and gasket thickness, aligns with this ratio for optimal performance.
What are the specific machining requirements for the BH574-950-020 pistons?
When using the BH574-950-020 pistons, it's crucial to ensure the correct bore clearance is achieved. The pistons should be fitted to a 3.937" bore, and ring gaps must be set according to your engine's intended use and RPM range. Always consult with your engine builder for precise specifications.
What is the weight of the BH574-950-020 pistons and how does it affect performance?
The BH574-950-020 pistons weigh 441 grams each. This weight is a consideration for engine balance and overall performance, especially at higher RPMs. Lighter pistons can improve throttle response and reduce stress on the engine components.
Do the BH574-950-020 pistons come with valve reliefs?
Yes, the BH574-950-020 pistons feature two valve reliefs. This design is essential for clearance with the Hemi V8's valves, especially at higher lift profiles. Ensure your camshaft specifications are compatible with these reliefs.
What is the pin size for the BH574-950-020 pistons?
The BH574-950-020 pistons have a pin size of .927" x 2.250". Ensure that your conrods are compatible with this pin size for proper fitment and performance.
