Rare and high value don't always go together. I have a rare Vega (Cosworth Twin Cam) but I couldn't sell it for the same price that a low mileage Yugo recently was sold for. Go figure!
Right now, any V-8 early Firebird will sell for more than the same car with a six in it, even the impressive OHC six. Market determines the price, not how many or few were produced. I'm not too current on the price range but I'm sure others here are.
