Unlimiteds are bloody awesome. I've been to Reno a few times for the races. Mustangs have always been my favorites though. Most of the Furies have had their British Rolls-Royce Centarurus engines with Wright R-3350 or Pratt Wasp engines and different props.

The Bearcats are pretty cool too. Used to talk with a guy that owned a Bearcat and Mustang but never raced them.

Every attempt to build a modern version has failed. Look at the Pond Racer. designed and built by Rutan but never could get the engines cooled off enough and finally burner through the firewalls.

There was a guy named "Lefty" something that used to race a P-38 Lightning. And there's a guy who races a Corsair.
It used to seem to go in cycles, for a few years no one could touch the Mustangs, then they did something to the Radial engines that made the F8 Bearcat's the bird to beat. Not sure if any one ever raced an F-10 Tomcat, I seem to recall one.
Still bugs me when they modify the cockpit shape though
