Eagle Ford 351W 4.000in Crank 2.750in Mains 6.200in H-Beam -15.8cc 4.060in Pistons Rotating Assembly

Eagle is well-known for making strong internal engine components, and this rotating assembly for Ford 351W engines is a prime example. If you're building a performance engine or rebuilding your top end, this package gives you the core pieces needed to get your short block started. It's designed to handle more power than stock, making it a solid choice for builds aiming for increased horsepower and torque.

This assembly features a 4.000-inch stroke crankshaft, which is a common upgrade for increasing displacement and power potential in a 351 Windsor. Paired with it are 6.200-inch long H-beam connecting rods. The H-beam design is popular for its strength and ability to withstand higher RPMs and increased cylinder pressures. The included pistons are 4.060 inches in bore size and have a -15.8cc dish volume, which will affect your final compression ratio depending on your cylinder head volume. This kit is a well-built foundation for a performance Ford engine.

When assembling your engine, pay close attention to bearing clearances and ring gap settings as recommended by Eagle and your piston manufacturer. This rotating assembly is a significant part of your engine's internal strength and performance. Please note that this part is not CARB approved and cannot be shipped to California.
