When I was selling ported magnum manifolds I only found the 53009376 (pic in first post) manifold on '96-'98 318 and 360 Jeeps Grand Cherokees. I haven't found that particular manifold on any other vehicle although there might be some other use on another year or engine. They make different styles (shapes) of magnum manifolds for other vehicles like the Dodge van (last pic in first post) that have the large ports but they fit differently. The '92/'93 magnum vehicles also had large ports but they are harder to find. Treblig
