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 bore clearance for the BH64-10-035 pistons?
For the BH64-10-035 pistons, a typical bore clearance of 0.0030" to 0.0035" is recommended. However, final clearance should be determined by the engine builder based on specific application and tolerances.
What compression ratio can I expect with the BH64-10-035 pistons in a 6.4 Hemi engine?
The BH64-10-035 pistons are designed to achieve a compression ratio of 10.0:1 when used with the appropriate 6.4 Hemi head. Ensure that the head gasket and combustion chamber volume are factored into the final calculation.
What type of ring gaps should I set for the BH64-10-035 pistons?
For the BH64-10-035 pistons, ring gaps should be set according to the intended use of the engine. A common starting point is 0.020" for the top rings and 0.022" for the second rings, but adjustments may be necessary based on boost levels and RPM.
What is the weight of the BH64-10-035 pistons and how does it affect performance?
The BH64-10-035 pistons weigh 503 grams each. Lighter pistons can improve engine response and reduce stress on the connecting rods, but ensure that the overall rotating assembly is balanced for optimal performance.
Are there any specific machining requirements for the BH64-10-035 pistons?
Yes, the BH64-10-035 pistons may require careful attention to bore size and ring land machining. Always verify the fitment and ensure that the piston-to-wall clearance is within recommended specifications for optimal performance and longevity.
