According to Brauer and to many fans, the muscle car's golden age came to an end in 1971. However, a small but determined group of engineers at Pontiac remained undeterred, and created an evolved Ram Air IV engine, which turned up under the hood of the 1974 Firebird.
Despite its late vintage, Brauer called this Trans Am "a fully capable muscle car." The current market value of the 1974 Pontiac Firebird Trans Am SD455 is $75,000.
