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 and stroke for the BF6160-STD pistons?
The BF6160-STD pistons are designed for a 4.125-inch bore and a 4.000-inch stroke, making them suitable for a Small Block Ford engine with these specifications.
What compression ratio can I expect with these pistons?
These pistons provide a compression ratio of 11.6:1 when used with 62cc TFS Twisted heads, which is ideal for performance applications. Ensure that your engine is properly tuned to handle this compression.
What type of ring thickness do these pistons use?
The BF6160-STD pistons utilise a ring thickness of 1.5mm for the top and second rings, and a 3.0mm oil ring. Proper ring gap settings are essential for optimal performance.
What is the weight of the BF6160-STD pistons?
Each BF6160-STD piston weighs approximately 458 grams. It's important to consider this weight when balancing your rotating assembly for performance applications.
Do these pistons have valve reliefs, and how many?
Yes, the BF6160-STD pistons feature three valve reliefs, which are designed to accommodate the valve clearance requirements of high-performance Small Block Ford engines.
