The Eagle rotating assembly for Ford 351W pairs core rotating components in a single kit: a 4.000" crank, 2.750" main journals, 6.200" I-beam rods and 4.040" pistons. This assembly collects the crank, mains, connecting rods and pistons into one package to simplify short-block builds or engine refreshes where those specific dimensions are required.
