Shelby GT 500
Mustang had some performance versions like the GT with the 289 HiPo V8 engine or the Shelby GT 350 in 1965. However, the first true performance Mustang with a big block engine and respectable 0 to 60 mph times was the 1967 Shelby GT 500. Bigger and more powerful than before, 1967 GT 500 featured a new design with a modified front and rear end. It also had a big 427 V8 engine with 335 HP and 420 lb-ft of torque.
In those days, Ford was notorious for underrating the power output of their engines, so the 335 HP rating sounded too low for a big 427. Car enthusiasts claim the real power was closer to the 400 HP range and performance figures backed that claim. The 0 to 60 mph time was 6.5 seconds, which was good for the day. Thanks to suspension modifications, the GT 500 could handle the curves well, too.
The Shelby GT 500 was one of the first models to receive collector car status. This affected the prices, which are not that high, but still lofty at around $160,000 for good examples.
Chevrolet Camaro SS
Chevrolet introduced the Camaro a full three years after the Ford Mustang. They offered a better package and two true muscle versions, the SS 350 and SS 396. Both produced more than 300 HP. Those Camaros were among the fastest factory pony cars on the market. Chevrolet was reluctant to put bigger engines in the Camaro.
But in 1969, they produced a small number of 427 Camaros. They even built 69 examples of the ZL1 Camaro with the Corvette ZL1 engine. The regular Camaros are common and plentiful on the muscle car market, but the best looking is the 1969 model. If you choose to buy the 350 SS, expect to pay around $45,000 for decent examples.
But if you go the big block route and purchase the mighty 396 SS, expect to pay around $80,000. And, if you are planning to by a super rare ZL1 model, be ready to give close to half a million dollars.
Pontiac GTO takes all the credit for being the first modern muscle car, but not a lot of people know the Oldsmobile 442 started the same year as the Pontiac. However, Oldsmobile was much more discrete about advertising a new model, so they offered as just an option on the Cutlass line. From the beginning, they marketed the 442 was marketed as a “gentleman’s hot rod.” It was an elegant, well-equipped muscle car with luxury appointments, reserved styling and brutal performance.
The name, 442, caused a lot of controversies back in the day, but the meaning was simple. It has a 400 CID engine, four-barrel carburetor and dual exhaust. Of course, you could order it with automatic, but if you wanted the most out of your 442, you would get the manual. In 1970, Oldsmobile introduced the biggest engine in the muscle car class, which was the 455 V8. They installed it in the 442.
This created one of the fastest cars of the era, especially with performance-oriented W30 optional package.Today, car fans seek the 442 for its style, discontinued brand and performance, so the prices are strong. For a nice 1970 442 with the 455 engine and the desirable W30 package, be ready to pay around $70,000.
Ford Mustang Boss 429
The mythical Mustang Boss 429 is a proper muscle car legend. Ford conceived it in 1969 as a pure racing engine intended for use in NASCAR championships. The Boss 429 featured a totally different engine architecture than the rest of Ford’s big blocks. The Boss 429 was much wider and had semi-Hemi combustion chambers. This helped achieve higher revs, better flow inside the head, as well as more power and torque.
Factory-rated at 375 HP, this unit produced over 500 HP in reality and much more in race trim. Ford decided to put this engine into the Mustang, creating a limited production Boss 429. But NASCAR decided not to homologate it since the series only accepted intermediate and full-size cars. The Mustang was a pony car model, so Ford homologated the Torino Talladega as the body and the Boss 429 as the engine. It participated in the 1969 season with Torinos and Mercury Cyclones powered by Boss 429 engines.
Those cars proved successful, winning 30 out of 54 races that year. The secret was the engine because they designed the Boss 429 to run at high RPMs for long periods of time. It also reached its peak power high in the RPM range. That is why the Mustang Boss 429 never fulfilled its street racing potential. The powerful engine required a long super-speedway track to show its true power, not those short quarter-mile stretches.
Available in 1969 and 1970 as an engine option on a Mustang Sportsroof, they made the Boss 429 in around 1,300 examples. This car has become a highly sought-after model in present years. The best Boss 429s cost around half of million dollars, but you can find a decent model in the $200,000 to $300,000 range.
