You state, "I want to rebuild..." So you must be technically savvy enough or you plan on doing some serious learning. If so it will probably cost less than half, except expect some very expensive tuition in the school of hard knocks. However, on the other side you will have a real knowledge of what is in your engine, and how to fix it. On the other hand, maybe you meant your going to pay to have someone do it, in which case you should find a local builder who will be around to maintain it as long as you plan on owning it. It will require a lot more know how than a stock engine.
