The Chevrolet Chevelle is an iconic muscle car that underwent several transformations throughout its production years. Among the most notable models are the 1967 Chevelle and the 1970 Chevelle, each with its unique characteristics and features. In this article, we'll explore the main differences between the 67 Chevelle vs 70 Chevelle to help you understand what sets these classic cars apart.
Design Evolution
The design evolution from the 1967 Chevelle to the 1970 Chevelle marked a significant change in the vehicle's overall appearance. Each model year brought updates that enhanced the car's style and presence on the road.
1967 Chevelle Design
The 1967 Chevelle retained the classic muscle car look with clean lines, a slightly curved body, and a wide stance. It featured a more refined grille and sharper headlight design compared to earlier models, giving it a sleek yet aggressive look.
- Body Style Options: The 1967 Chevelle was available in various body styles, including coupe, convertible, and sedan, making it versatile for different preferences.
- Trim Details: Chrome accents and bold emblems were prominent on the 1967 model, highlighting its sporty and elegant appearance.
1970 Chevelle Design
The 1970 Chevelle introduced a more muscular and bold design, emphasizing its performance-oriented nature. It had a broader and more pronounced front end, with quad headlights and a new grille that added to its aggressive look.
- Cowl Induction Hood: One of the standout features of the 1970 model was the optional cowl induction hood, which not only enhanced the car's aesthetics but also improved airflow to the engine.
- Distinct Rear End: The rear end of the 1970 Chevelle featured a redesigned taillight configuration, giving it a more modern and eye-catching appearance.
The 67 Chevelle vs 70 Chevelle design changes reflect the shift towards a more performance-driven and visually striking muscle car in the early 1970s.
Engine Choices
One of the most significant differences between the 1967 and 1970 Chevelle models is the variety of engine options available. Each model year offered powerful engines, but the 1970 Chevelle took things to a whole new level.
1967 Chevelle Engine Options
The 1967 Chevelle came with a range of engine choices that catered to both everyday drivers and performance enthusiasts. The available engines included the following V8 options:
- 283 cu in V8 with up to 195 horsepower for a balanced performance.
- 327 cu in V8 offering up to 325 horsepower, making it a popular choice for muscle car fans.
- 396 cu in V8 that delivered an impressive 375 horsepower for high-performance driving.
1970 Chevelle Engine Options
The 1970 Chevelle is often celebrated for its powerful engine lineup, which included some of the most legendary big-block V8s of its time:
- 350 cu in V8 providing up to 300 horsepower, ideal for a balanced mix of power and control.
- 402 cu in V8 that replaced the 396, delivering strong mid-range performance.
- 454 cu in V8 LS6 capable of producing a jaw-dropping 450 horsepower, making it one of the most powerful muscle car engines ever.
The 1970 Chevelle's engine lineup set a new standard for power and performance, highlighting the key differences in the 67 Chevelle vs 70 Chevelle battle.
Suspension And Handling
Suspension and handling are crucial aspects that influence the driving experience, and both the 1967 and 1970 Chevelle models offered different setups to enhance their ride quality.
1967 Chevelle Suspension
The 1967 Chevelle came with a basic suspension system that was effective for its time but lacked some of the advanced features seen in later models. It featured:
- Coil Spring Suspension: Provided a comfortable ride but was more suited to straight-line performance rather than cornering.
- Standard Drum Brakes: Common in the 1960s, the drum brakes were effective but less responsive compared to modern disc brakes.
1970 Chevelle Suspension
By 1970, Chevrolet had improved the Chevelle's suspension and handling capabilities to match its increased power:
- Front Disc Brakes: The addition of front disc brakes enhanced stopping power and improved safety.
- Heavy-Duty Suspension: Upgraded components were available for improved handling and cornering, making the 1970 Chevelle more agile and responsive.
The enhancements in the 70 Chevelle's suspension system allowed it to handle the increased horsepower more effectively, providing a superior driving experience compared to its predecessor.

I am looking for a partial floor pan for a 1969 Chevelle Concourse (station wagon) to replace the drivers side (front). Also my drivers side header (collector box ) is lower than passenger side and keeps on bottoming out. Any solutions to these problems?

Hey Earl,
For the driver-side floor pan in your 1969 Chevelle Concours station wagon, a standard front floor pan for a 2-door or 4-door Chevelle coupe or sedan will often work with minor trimming. While wagon-specific pans aren’t always listed separately, many manufacturers like Sherman or Auto Metal Direct make universal front patch panels that will fit the footwell area with some adjustment. Just double-check measurements before welding it in.
As for your header bottoming out on the driver’s side, that’s a common issue, especially if the collector hangs a bit lower than the frame or suspension clearance allows. You could try a few things:
Make sure your engine and transmission mounts aren’t sagging. A worn-out mount can cause the engine to tilt and drop the header lower on one side.
A different header brand or series may give you better ground clearance. Look for tight-fit or mid-length headers, especially ones built for clearance on lowered vehicles or those with wider frames like wagons.
Lastly, exhaust shops can sometimes modify the collector angle slightly to tuck it up closer to the floor without affecting performance.
If you’d like to go over part options or have more details to share, give us a call at 1-800-345-4545 and one of our tech specialists will be happy to help.
