1970 Chevrolet Chevelle SS 454 LS6
The 1970 Chevrolet Chevelle SS 454 LS6 was a beast, plain and simple. The 450 horsepower assigned to this Chevelle V-8 is the highest power rating ever given to a car from the original muscle car era, according to Brauer.
The high rating, however, was an understatement. "Even this rating was below the engine's actual horsepower, which was likely somewhere between 470 and 500 horsepower," he said. This Chevelle's current market value is $75,000.
1970 Pontiac GTO Judge Ram Air IV
"Pontiac's GTO started the official muscle car era in 1964," Brauer said. "By 1970 the competition on the street, and in the showrooms, required every automaker to step up their efforts."
Even Pontiac itself had to raise its game, which it did by introducing the GTO Judge. According to Brauer, it's "powered by the Ram Air IV engine, a 400 cubic inch V-8 with special high-flow heads and unique exhaust manifolds." Its current market value is $80,000.
1968 Ford Mustang GT500KR
"Carroll Shelby has a history of hot-rodding Mustangs that started in 1965," Brauer said of the late Ford Motor designer. Production of his Mustangs switched from his own shop to the Ford facilities in 1968, when the GT500KR was built.
Brauer called this muscle car "one of the most attractive and capable Shelby Mustangs ever created." He added that only 933 coupes were built, along with 318 convertibles. Its current market value is $130,000.
1969 Ford Boss 429 Mustang
In 1969, NASCAR was a major influence on automobile sales for the general public. "Winning on Sunday really would sell cars on Monday," Brauer said, so Ford responded by putting a Boss 429 racing engine into its most high-profile car, the Mustang.
The result was the 1969 Ford Boss 429 Mustang, which had a production run of 859 units, every one of which was built by an outside contractor. The current market value is $220,000.
