Product Details

New exhaust manifold conversion kit for OMC Ford 302/351 marine gas engines. Replaces the old end rise (log style) manifolds and risers, part numbers 913682, 913683, 909218, 982680, or 909863, with new and more efficient center-rise manifolds and risers.

  • This kit does not replace the older “Banana” style OMC Ford manifolds.
  • These manifolds utilize one bolt per port, instead of two like original OMC manifolds. This is normal and will not cause any problems.
