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 size for the SS5500 pistons?
The SS5500 pistons are designed for a bore size of 4.560 inches. Ensure that your engine block is machined to this specification for optimal performance.
What is the compression height of the SS5500 pistons?
The compression height for the SS5500 pistons is 1.120 inches. This measurement is crucial for achieving the desired compression ratio in your engine build.
What type of gas porting is included with the SS5500 pistons?
The SS5500 pistons feature gas ports, which enhance ring seal and improve performance by allowing better oil control and reducing blow-by. Ensure proper machining and fitment to take full advantage of this feature.
What is the weight of the SS5500 pistons?
Each SS5500 piston weighs 592 grams. It's important to balance your rotating assembly, including these pistons, to maintain engine reliability and performance.
Are the SS5500 pistons suitable for use with angle milled heads?
Yes, the SS5500 pistons are designed to be compatible with angle milled heads. However, ensure that your engine builder accounts for any changes in clearance and compression ratio resulting from the milling process.
