This would be a really bad idea. I’m sure many others will weigh in, so I’ll be relatively brief. Fill the crank case with break in oil, start the engine and idle for as short a time as possible, get the airplane in the air at full power, cruise climb over the airport somewhere between five and 8000 feet, and since you’re in congested airspace in Florida, I would do VFR circles over the airport varying between 75 and 100% power until the cylinder head temperatures show a significant drop. I’d say 20-30°. Mine usually take a little over two hours. I know some say it takes them longer. You don’t want to be out of gliding distance of an airport. Change the oil to your usual, cut open the filter and look for metal, and then think about your long flight when you’ve got another 20 hours on the airplane.
