This Pure Stock Muscle Car Drag Race shows that a 1965 GTO was no match for the legendary 1970 Chevrolet Chevelle SS 454.
First car is a 1970 Chevrolet Chevelle Super Sport, and the other a 1965 Pontiac GTO. The 1970 Chevelle has a 454 V8. The ’65 GTO has a 389 V8. The 454 in the 1970 Chevelle SS is a LS6 and therefore rated 450 horsepower. The 389 in the Pontiac was rated 360 horsepower since it has a tri-power setup. The 1970 Super Sport Chevelle 454 has a Turbo 400 3-speed automatic transmission, while the 1965 GTO has a 4-speed manual. Weight including driver for the ’65 GTO is 3710 pounds. The 1970 Chevy Chevelle SS454 weight is a little heavier at 3848 pounds.
They made 20,547 Tri-Power equipped GTOs in 1965, but even few LS6 Chevelles; there were only 4475 LS6 Chevelles/El Caminos produced in 1970. Car Life tested a 1965 GTO with 4.11 gears and a 4-speed manual transmission and it ran 14.5 seconds @ 100 mph and 0-60 in 5.8 seconds…however, they had 2 staff members in the car.
The ’70 Chevelle LS6 SS454 was tested by Hot Rod magazine in May 1970 and it ran the quarter mile at 13.44 seconds @ 108.17 mph when equipped with 4.10 gears and a 4-speed transmission.
