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 are the specific applications for the CP Pistons S1702?
The CP Pistons S1702 are designed specifically for the Chevrolet Late Model SBC 350 engines. They are suitable for applications requiring a flat top piston with a two-barrel design, making them ideal for performance builds where weight reduction and strength are critical.
What is the recommended wrist pin size for these pistons?
The CP Pistons S1702 require a wrist pin diameter of .927 inches and a length of 2.000 inches. Ensure that your connecting rods are compatible, as they should have a width of .900 inches or less.
What machining considerations should I keep in mind when using these pistons?
When installing the CP Pistons S1702, it's essential to ensure the correct bore clearance is achieved. Additionally, verify that the ring gaps are set according to your specific engine build and intended use. Always consult your engine builder for precise machining requirements.
Can these pistons be used with different stroke lengths?
Yes, the CP Pistons S1702 can be used with a 3.750-inch stroke and a 6.000-inch rod length. However, ensure that your engine's overall configuration and clearances are suitable for these specifications.
What features do these pistons have for performance enhancement?
The CP Pistons S1702 come with gas ports, accumulator grooves, and anti-detonation grooves, which enhance performance by improving combustion efficiency and reducing the risk of detonation. These features are particularly beneficial for high-performance applications.
