CP Piston Bullet Race Series Big Block Chevy 13.0CC Dome 4.500 Bore 4.250 Stroke 6.385 Rod Set Of 8

If you're building a high-performance Big Block Chevy engine for racing or serious street use, a strong set of pistons is crucial. These CP Pistons Bullet Race Series pistons are designed to handle the demands of a powerful V8. They feature a 13.0cc dome volume, which works with specific compression ratios depending on your cylinder head chamber size and gasket thickness. The 4.500-inch bore size is standard for many Big Block Chevy applications, and they are designed to work with a 4.250-inch stroke crankshaft and a 6.385-inch connecting rod.

CP Pistons are well-known in the racing world for their robust construction. These are forged pistons, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for engines that will see high RPMs and significant cylinder pressures. The Bullet Race Series is a popular choice for builders looking for a reliable piston that can withstand aggressive use. They are designed for a direct fit into the specified bore size, simplifying installation for experienced engine builders.

This set includes eight pistons, enough for a complete V8 engine. Remember that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, always consult your engine builder or the manufacturer's specifications for proper installation, ring gap, and assembly details.
