Here's Why You Should Fondly Remember The 1970 Chevrolet Chevelle SS 454 (2024)

For a Ford Mustang fan, 1970 was not a good year. The two top dogs in the muscle car hierarchies were roaming the streets looking for a challenge. The Dodge Hemi and the Chevrolet Chevelle SS 454 were on the top of the list, jockeying back and forth for the number one spot. When the two cars met, nine out of 10 times, the Chevy came out as the winner. Not to say that the Dodge did not give a good race because the two were almost identical regarding drag times. The 1970 Chevelle was one of those cars that muscle car enthusiasts fought to get ahold of, for a good reason. Here are some of the most important things to remember about the '70 Chevelle SS to gain a better appreciation of the car in every sense.

In 1970, GM finally lifted the horsepower restrictions that had been in place for almost a decade. The ban limited the displacement that could be manufactured for any engine being dropped into a mid-sized muscle car, such as the Chevelle and Impala. The reason for this is claimed to have been due to safety concerns, but there is a much darker reason for this ban. In the early 60s, the Attorney General threatened to charge the company with various antitrust violations. To keep the company out of trouble, bans were placed on the factory-backed racing teams, which also trickled down to the production models such as the Chevelle SS.

When ordering the 1970 Chevelle SS from the production plant, a consumer had a new option to check off, the RPO Z15 box. Giving this box a little check lifted the car being ordered into a new level of muscle because it opted for the big block 454, the biggest engine ever placed in any production car up to and through 1970. It was said to produce up to 450 horsepower and could push out around 500 pound-feet of torque. This large engine may have been seen in early versions of the Chevy muscle car lineup, but because of the displacement ban, they were not allowed under the hood of any mid-sized car. That is, until 1970 when GM muscle cars hit their all-time power and torque peaks.

Throughout the '60s, the Super Sport version was offered on many different GM cars. It was a higher trim level on most of them, offering a more aggressive look, with additions to the engine, suspension, and drivetrain to ensure it was the most sporty version of the car on the roads. The square looks and more significant stances began to disappear in 1970 when the new styling of the cars started to become more rounded. The updated and upgraded '70 Chevy Chevelle SS received a removal of the sharper edging that had signified the '60s, making the car more eye-appealing and more aerodynamic.

For the first part of the year, the 454 SS car had the LS5 under the hood. This engine was a beast in its own right, producing around 390 horsepower and could pound out up to 400 pound-feet of torque. It was a top competitor on the streets, but it was not enough, according to the Chevy engineers, because the middle of the model year brought about the LS6 engine. This beefed-up version of the LS5 used the same block, but everything else was upgraded, and on top of the engine manifold sat a low-rise aluminum intake with a large 750 cfm Holley four-barrel carburetor. This combination bumped the horsepower of the LS6 to 450 horsepower and 500 pound-feet of torque.

5 Chevy Displayed Underrated Horsepower Limits

Here's Why You Should Fondly Remember The 1970 Chevrolet Chevelle SS 454 (6)

There are a couple of reasons why the big car manufacturers displayed underrated horsepower limits and amounts. The first, and the one used the most often, is that the lower the horsepower is under the hood, the lower the insurance premiums will be. Of course, there is a darker and more unethical reason going around as well. NASCAR has specific limits on the horsepower that a car can produce to be part of the year's racing schedule. That meant if the carmakers displayed the actual horsepower of an engine that it would not be allowed to compete, so the manufacturers gave false information to ensure that their cars were able to race throughout the season.

Bucket seats were optional in the 1970 Chevy Chevelle SS 454, which offered more comfort for the driver when mashing on the accelerator. However, that was not special considering that many other cars also offered bucket seats. What made the Chevelle's interior unique was how the instrument cluster was made. It had three large round openings in the center for the speedometer, fuel gauge, and tachometer. Along the sides, the warning lights for temperature and battery amps were replaced with gauges, giving the driver more accurate readings.

1970 was an exciting year for Chevy muscle car lovers because of the ban restrictions by GM being lifted. They knew that they could go down and order their own muscle car with the biggest engine available without worrying about being told they couldn't get the best of the best. One main issue appeared when they got to the order form and began filling it out. Consumers could not buy a base-level Chevelle unless they added some available options. Granted, that was not much of a problem for those that wanted the SS version with the 454 under the hood, but for those wanting a basic car that looked and drove good, they were simply out of luck.

Back in the day when muscle cars ruled the streets, it was not uncommon to see two of the top dogs racing for titles. By titles, it is not meant pink slips.

The Hemi was close and would win some of the races between the two, but the Mustang fell short even with a great driver.
