Eagle Ford 351W 4.000in Crank 6.250in H-Beam -6.5cc Flat Top 4.040in Pistons Balanced Assembly

This balanced rotating assembly from Eagle is built for serious Ford 351W performance builds. What you get in this package is a complete rotating assembly ready to be installed into your engine block. It includes a forged 4.000-inch stroke crankshaft made from strong 4340 steel, designed to handle significant power. Paired with the crank are 6.250-inch H-beam connecting rods, which are well-built for high-stress applications and come with 7/16-inch ARP 8740 bolts for a solid connection.

The pistons included are forged 4032 aluminum flat-top units from Mahle, measuring 4.040 inches in bore size and featuring a -6.6cc dish, which is ideal for achieving a desired compression ratio with many common cylinder head combinations. This assembly also comes with plasma-moly file-fit piston rings, giving you the flexibility to set your ring gap precisely for your engine's specific needs, whether it's naturally aspirated, boosted, or running nitrous. To top it off, King XP series rod and main bearings are included, known for their robust construction and excellent performance under demanding conditions.

This balanced assembly means Eagle has pre-balanced the rotating components, saving you a significant step and potential cost in your engine build. This is a popular choice for racing applications, including those using nitrous oxide or forced induction, where reliability and strength are paramount. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
