1975 Camaro Parts and Restoration Information

1975 Camaro Parts and Restoration Specifications

In 1975 Chevy decided to drop the Z28 model and after the loss of the SS model was steadily becoming a more conservative vehicle under the hood.

A steady stream of vehicle related regulations, continuing fears of oil shortages and a bigger focus on fuel efficiency may have been shorting the Camaro’s Horsepower but not its production levels. In 1975 the Camaro stood alone in the ‘pony car’ category.

1975 Spotters Guide & New Features
Hey, have you seen my Leisure suit? 1975 saw a couple major changes to the Camaro, some visible, some not. One fault of the Camaro was its poor rear visibility. To remedy this, the rear window was redesigned to be a “wrap around” design. With the elimination of leaded gas and in an effort to further reduce emissions, the Catalytic Converter debuted. This required a modification to the passenger side floor.
The Rally Sport option reappeared, this time as a paint & trim package.
Note: The Z28 was not available in 1975. There is no such thing as a 1975 Z28, even if you’ve seen or bought one on e-bay. Of the one built, it was supposed to have been destroyed before it left GM.

  • power plant selection limited to 250 6 cylinder, or 2 versions of the 350
  • Rally Sport option returns as RPO Z85 in midseason.
  • RPO Z28 is dropped but a production figure of one (1) unit is shown.
  • Introduction of the “wrap around” rear window.
  • Central (power) locks debut
  • Sports Decor (Z08) introduced, then withdrawn mid-season.
  • Finned rear brake drums
  • All cars got Catalytic converters (yippee), and raised passenger floor to make it fit.
  • Big LT change was using Birdseye maple woodgrain instead of meridian walnut.
  • Twin exhaust tail pipes for all V8’s
  • HEI standard on all engines.
  • Deep pile carpet added
  • New radios offered
  • A/C now available with 6-cylinder.
  • Cruise control becomes available.
