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 BH64-950-010 pistons?
The BH64-950-010 pistons are designed for a compression ratio of 9.5:1 when used with the 6.4L Hemi head. Ensure that your engine's overall setup, including head gasket thickness and combustion chamber volume, aligns with this ratio for optimal performance.
What machining considerations should I keep in mind when using these pistons?
When installing the BH64-950-010 pistons, ensure that the bore clearance is set correctly according to your engine's specifications. Additionally, check that the ring gaps are tailored to your specific application, especially if you're running higher RPMs or boost levels.
What is the pin size for the BH64-950-010 pistons?
The BH64-950-010 pistons feature a pin size of .927 inches and a length of 2.250 inches. Ensure that your conrods are compatible with this pin size for proper fitment.
What type of valve reliefs do the BH64-950-010 pistons have?
These pistons come with two valve reliefs, which are designed to accommodate the valve geometry of the 6.4L Hemi engine. Verify that your camshaft and valve train setup do not interfere with these reliefs during operation.
What is the weight of the BH64-950-010 pistons?
The BH64-950-010 pistons weigh 484 grams each. When building your rotating assembly, consider this weight in relation to your crankshaft and conrod specifications to maintain balance and performance.
