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 BC1200-060 pistons?
The BC1200-060 pistons are designed for a compression ratio of 13.1:1 when used with a 64cc cylinder head. Ensure that your engine's overall setup, including camshaft selection and fuel quality, can support this compression.
What bore size do the BC1200-060 pistons require?
These pistons are designed for a bore size of 4.185 inches. Proper machining of the cylinder bores is essential to achieve the correct clearance for optimal performance.
What type of valve reliefs do the BC1200-060 pistons have?
The BC1200-060 pistons feature two valve reliefs. This design helps accommodate the valve lift and timing of high-performance camshafts commonly used in Small Block Chevy applications.
What is the weight of the BC1200-060 pistons?
Each BC1200-060 piston weighs 452 grams. When building your engine, consider the total rotating mass and balance it with the crankshaft and connecting rods for optimal performance.
What is the pin size for the BC1200-060 pistons?
The BC1200-060 pistons use a pin size of .927 inches with a length of 2.500 inches. Ensure that your connecting rods are compatible with this pin size for proper fitment.
