My uncle has an '03 Chief and due to circumstances out of his hands his engine is not only no longer serviceable but no longer rebuildable. We are looking for an engine to replace the PP100 with the least modifications (e.g. changing transmissions, moving engine mounts,) What engine would swap into the Chief with the least work, making more an engine swap and not a custom build at a shop. A swap we can do but money is a factor and we just want to get his bike up after a long while down. For what it's worth the vin is 5CDNNCAJ93G010420. Thanks for any and all input.
