1965 Pontiac Lemans GTO

Again for 1965 the GTO was an option available on the Tempest LeMans models of Pontiac. The GTO popularity had been growing and Pontiac Immediately started to add unique identifiers to GTO equipped cars. Front grills, rear fender sides and trunk were now marked with bold GTO letters. In addition to more noticeable markings the hood of the GTO equipped cars featured a very distinctive hood scoop, a feature that would follow GTO throughout its production years.

Horsepower actually increased over last year’s availability. A new LeMans GTO could be ordered with an optional 389, 360 Horsepower engine. Standard engine was 389 cubic inch rated at 335 horsepower. Additionally one could order a tri-power equipped 389 cubic inch motor that featured 3 - 2-barrel carbs.
