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 S1346B pistons?
The S1346B pistons are designed for a compression ratio of 13.5:1 when used in a 355ci SBC engine with Brodix ASCS heads. Ensure that your engine's setup, including head gasket thickness and combustion chamber volume, supports this compression ratio.
What machining is required for the S1346B pistons?
When installing the S1346B pistons, ensure that the bore clearance is set correctly according to your engine's specifications. Additionally, the ring gaps should be tailored to your specific application, especially if you're running high RPMs or boosted applications.
Can I use these pistons with any SBC 355ci engine?
The S1346B pistons are specifically designed for use with Brodix ASCS heads. While they can fit a standard SBC 355ci engine, ensure that your engine's specifications align with the piston design, particularly regarding dome height and compression requirements.
What is the weight of the S1346B pistons, and how does it affect performance?
The S1346B pistons weigh 490 grams each. This lightweight design helps reduce reciprocating mass, which can improve engine response and RPM potential. However, always consider the balance of the entire rotating assembly for optimal performance.
What type of gas ports do the S1346B pistons feature?
The S1346B pistons come equipped with gas ports, which help improve ring seal and reduce blow-by by allowing combustion gases to pressurise the ring pack. Proper installation and clearance settings are crucial for maximising the benefits of the gas ports.
