The GTO rolled into 1970 with some exterior changes that included a redesigned nose (which ended the run of the GTO’s optional concealed headlamps), a redesigned rear that incorporated the taillights into the bumper, and reworked body panels that had sharp creases pressed into the front fenders, the quarter panels as well as the leading edge of the door.
Pontiac’s 350-hp, 400-cu.in. V-8 was standard issue, but the deep-breathing Ram-Air III package upped the ante to 366 hp, while the Ram Air IV belted out 370 hp. The 455 was available for the first time in the 1970 GTO as well. With 10.25 compression, the biggest-displacement Pontiac effortlessly made 360 hp and 500-lb.ft of torque.
A Muncie three-speed was the base transmission, but GTO buyers could opt for a close-ratio Muncie M21 four-speed manual, a wide-ratio M20 gear box, or a Turbo Hydra-Matic 400 three-speed automatic.
Of the approximately 40,000 GTOs that Pontiac built in 1970, fewer than 10 percent were convertibles. About half of those were equipped, like this example currently for sale on Hemmings.com, with an automatic transmission and the base 400.
