Carrillo BC1045-040 SBC Piston Set 4.040 Bore 5.700 Rod Dome +5cc

The Carrillo BC1045-040 is a high-performance forged piston set engineered specifically for Small Block Chevy applications with 23-degree cylinder heads. These pistons feature a dome configuration with +5cc volume, designed to optimize compression and power output in racing and high-performance street engines.

Key Specifications:

• Bore Size: 4.040 inches
• Stroke: 3.500 inches
• Rod Length: 5.700 inches
• Dome Volume: +5cc
• Compression Ratio: 11.4:1 with 64cc cylinder heads
• Compatible with all 23-degree cylinder heads

Carrillo pistons are precision-machined from high-strength aluminum forgings to deliver exceptional strength-to-weight ratio and dimensional accuracy. The dome design increases compression for improved cylinder pressure and power production, making these pistons ideal for naturally aspirated performance builds. The specific geometry is optimized for use with 5.700-inch connecting rods and provides proper piston-to-valve clearance with compatible 23-degree head designs.

Applications: Small Block Chevy engines built with 4.040-inch bore diameter, 3.500-inch stroke crankshaft, and 5.700-inch connecting rods. Typical displacement with these specifications is approximately 355-358 cubic inches depending on deck height.
