tadd, I know where your coming from, I have built many aircraft engines and porsche engines, IMHO the aircraft are cheaper and eaiser to build, The aircraft have things they use only because the process to get the repair approved has been done, you would not belive the paper work involved in this, this does not mean its the best out there, just the most expensive in many cases. One thing to think about, My O200 in my plane will need a rebuild in about 1500 hours, if I had an hour meter on my car it would be equal to about 5000 hours on the porsche engine
