SBF Rotating Assembly Kit 289/302

The EAGLE SBF Rotating Assembly Kit 289/302 is a complete, ready-to-install engine rotating assembly engineered for Small Block Ford platforms requiring high-displacement performance. This kit is built for restoration shops, performance builders, and serious engine rebuilders who demand factory-grade reliability paired with forged internals designed to handle elevated horsepower and sustained load cycles.

The rotating assembly serves as the mechanical core of any engine build—connecting the crankshaft, pistons, and connecting rods into a balanced, synchronized system that converts combustion pressure into rotational power. This kit features a forged crankshaft paired with forged pistons, 5.400-inch I-beam connecting rods, a 3.400-inch stroke, and a 4.030-inch bore, delivering 347 cubic inches of displacement. The combination yields a slightly oversquare configuration ideal for mid-range torque and RPM capability.

Builders restoring 289 or 302 Small Block Ford engines will find this kit compatible with original block castings and standard-bore specifications. Forged pistons resist detonation and ring flutter under boost and sustained RPM, while I-beam rod geometry provides superior strength-to-weight ratio compared to stock stamped designs. This assembly is a proven choice for street, marine, and light competition builds.
