Mountains up here (Midway, Utah, 5550' elevation, pass roads go up to 9k or 10k depending, my office is at about 7k).
Bugeyes have a 4.22 rear, right? I'll probably keep it in for now and see how it works with the 1275. A friend of mine in the local club has offered some storage space for the Midget tub if I need it, so I don't feel quite as pressured to make decisions just yet. I'll get the engine and transmission out, and then see what I feel like doing.
