Product Details
If you're building a high-performance Chevy 400 small block and looking to increase displacement and power, this Eagle rotating assembly is a solid foundation. It's designed to take your engine beyond its stock 400 cubic inches, giving you the potential for significantly more horsepower and torque. This kit includes a 3.875-inch stroke crankshaft, 6.000-inch H-beam connecting rods, and pistons sized for a 4.155-inch bore, effectively creating a stroker engine. This setup is ideal for those aiming for a powerful street machine or a dedicated race engine where increased displacement is key to performance.
Eagle is known for producing well-built internal engine components, and this rotating assembly is no exception. The crankshaft is forged for strength, ready to handle the stresses of increased combustion pressures. The H-beam connecting rods are a popular choice for performance builds due to their robust design and ability to withstand higher RPMs and loads compared to I-beam rods. The included pistons are designed to work with the specific bore and stroke of this assembly, and the -16cc dish volume helps achieve a desired compression ratio when paired with appropriate cylinder heads. This is a comprehensive package designed to work together, simplifying the process of building a stroker small-block Chevy.
When installing a rotating assembly like this, it's crucial to ensure all components are meticulously balanced by a professional machine shop. Proper balancing is essential for engine longevity and smooth operation, especially with a stroker combination. You'll also need to consider the appropriate cylinder heads, camshaft, and tuning to take full advantage of the increased displacement and potential of this engine build. Remember, this assembly is not CARB approved and cannot be shipped to California.
