Jackie's 1965 Pontiac GTO For Sale
1965 Pontiac GTO. Clean, FOR SALE make an offer. 6.5 liter V-8
Car Life tested a 1965 GTO with Tri-Power and what they considered the most desirable options (close-ratio four-speed manual transmission, power steering, metallic brakes, rally wheels, 4.11 limited-slip differential, and Rally Gauge Cluster), with a total sticker price of US$3,643.79. With two testers and equipment aboard, they recorded 0--60 miles per hour (0--97 km/h) in 5.8 seconds, the standing quarter mile in 14.5 seconds with a trap speed of 100 miles per hour (160 km/h), and an observed top speed of 114 miles per hour (182.4 km/h) at the engine's 6,000 rpm redline.
The 389 engines received revised cylinder heads with re-cored intake passages, improving breathing. Rated power increased to 335 hp (250 kW) at 5,000 rpm for the base 4—barrel engine; the Tri-Power was rated 360 hp (270 kW) at 5,200 rpm. The Tri-Power engine had slightly less torque than the base engine 424 lb·ft (575 N·m) at 3,600 rpm versus 431 lb·ft (584 N·m) at 3,200 rpm. Transmission and axle ratio choices remained the same. The three-speed manual was standard, while a four-speed manual or two-speed automatic were optional.
