71 Formula 455 HO with a M22.

Canyon Copper was called Burnt Orange on 1971 Chevrolets, Bittersweet on 1971 Oldsmobiles, and Bittersweet Mist on 1971 Buicks.

I agree about why this car has been sitting. Second Generation Firebird fans are usually really turned off by vinyl tops on these cars, and copper/brown is not a popular color with Formula Firebird fans. Even with the rare 455 H.O. and 4-speed, it's one of those cars where the overall visual appeal is hurting the sale.

Here's a 71 Judge in Canyon Copper.
