This 1969 Pontiac Firebird sat forgotten for years, its factory 400 engine buried under rat nests and grime, until the Turnin Rust crew finally got it running — and the exhaust blew out a literal dust storm in the process. Built originally for strip use, the car earned its Dirty Bird nickname on the spot. Watch to see what years of neglect actually did to a genuine factory 400-powered Firebird, and how much of it is still worth saving.
