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 height for the CP Pistons S1320?
The CP Pistons S1320 has a compression height of 1.550 inches, which is suitable for a 350 Chevy engine with a 3.500-inch stroke and 5.700-inch rods.
What is the dome height and how does it affect performance?
The dome height of the S1320 is 0.450 inches with a dome volume of 13cc. This design can increase compression ratio, which may enhance performance, but it's essential to ensure compatibility with your cylinder head and fuel type.
Can the S1320 pistons be used with angle milled heads?
Yes, the S1320 pistons are suitable for use with angle milled heads, allowing for better fitment and performance in modified engine setups.
What is the weight of the S1320 pistons and how does it impact engine dynamics?
The S1320 pistons weigh 477 grams. Lighter pistons can improve engine response and reduce reciprocating mass, but ensure your engine is balanced accordingly to maintain reliability.
What type of wrist pins are included with the S1320 pistons?
The S1320 pistons come with .927 x 2.750-inch wrist pins, which are included at no extra cost and are designed for optimal fitment and performance in your engine build.
