What's Included:

The longblock assembly includes engine block, cylinder heads, crankshaft, connecting rods, pistons, rings, engine bearings, oil pump, marine seals, marine cam shaft, tappets, timing components, brass core plugs, complete head assemblies, timing cover, oil pan, and marine circulating water pump. Engine gaskets are included with this assembly.

Key Features:

  • Bore and stroke: 4.0 x 3.6 inches (101 x 92mm)
