TRS-80 fever on ebay?!

I have a '74 Barracuda that's being restored. The original 283 was tossed out into the dirt by the previous owner, and a 440 dropped in. During the restoration, I found a cracked piston skirt, so I had the engine rebuilt. We're looking for some adapter plates to put it on the dyno, but the desktop calculation says 475 HP at the crank. http://tinymicros.com/vehicles/cuda/images/74Cuda_001.jpg and http://tinymicros.com/vehicles/cuda/images/74Cuda_002.jpg. The previous owner did a couple things I don't care for, such as making the inlets functional (well, air goes in, but it just goes down over the manifold, and nowhere useful), painted the bumpers, and lost the sheet metal where the exhaust should come through. I'm putting as much as possible back to factory as far as esthetics. Obviously it'll never show class 1 because the numbers don't match. Before I started the resto project, she could lay 110' of rubber on those crappy tires that are on there. --John
