1970 GTO & 1970 GTO Judge

For the 1970 model year the GTO took on a whole new look. Styling changes included a total Endura nosepiece with split oval grilles and dual headlamp housings (this new design eliminated the optional hide-away headlamps), creased body sides, a different rear-bumper and taillamps, and exhaust pipes that exited through a valance panel under the rear bumper. The hood-mounted tachometer and the Rally II wheels remained as available options.

The base engine for the 1970 GTO was a four-barrel carbureted 400 rated at 350 hp. Other available engines were the 400 cubic inch Ram Air III and 400 cubic inch Ram Air IV. The Ram Air III was rated at 366 hp and the Ram Air IV was rated at 370 hp. With GM finally lifting the 400 cubic inch corporate engine limit for the intermediate-size cars, new to the 1970 GTO option list was a 455 cubic inch engine rated at 360 hp.

The Judge option was once again available with functional Ram Air hoodscoops, a rear-deck spoiler, stripes, and “The Judge” decals.

The standard engine for The Judge was the 400 cubic inch Ram Air III while the 400 cubic inch Ram Air IV engine was an option. The functional hoodscoops were labeled with “Ram Air” decals for the Ram Air III cars and “Ram Air IV” decals for the Ram Air IV cars. Late in the model year, the 455 was made available in the Judge.

  1. Hi….I’m the new owner of a 1970 GTO Convertible that I bought in Atlanta and shipped to British Columbia. Wow what a car!! I love it.
    Is there information somewhere so that I can find out how many of these convertibles came from the factory with a hood tach?
    Thanks,
    Tom

  2. I see a subtitle under the “GTO” on the fender of the Red 1970 convertible. What does it say? What are the spec’s on that car?

    • The subtitle under the “GTO” on the fender of the red 1970 convertible is “455 CID”. This car is one of only 158 1970 Convertible GTOs with the 455 engine and 4-speed transmission combination.

  3. I have two 70 judges to restore, one tripple black, the other red, was a police car, both are basket cases, Black one numbers maching, red one missing transmisson, block, wan info on how many tripple black one with 4 speed and ac??

  4. How many 1970 Judges were made with a 455 engine, convertible, air, and every other option available? I have heard only 3 were made. Is that true?
    Thanks
