Pontiac restyled the front end of the GTO for 1970 and a rear anti-sway bar was added. The GM ban on engines over 400 cubic inches was dropped and the 455 cubic inch engine debuted, although it featured reduced output. Option 611, the "Tiger" button, allowed the driver to choose a less restrictive exhaust for more power. The cost was $63, but it was only in production for a couple of months.
