If you love classic GM muscle, then this video is a surefire winner as we head to the drag strip to watch a 1967 Pontiac GTO line up alongside a 1972 Chevelle SS 454.
Once again coming to us from the Cars And Zebras YouTube channel, the video is a little over eight minutes long and includes walkarounds and background info for both vehicles, as well as three rounds of racing action at the end.
As far as the specs are concerned, let’s start with that 1967 Pontiac GTO. Covered in bright green-blue paint matched with a black roof and redline tires, this thing definitely has the looks to turn some heads. Lift the hood and you’ll find the upgraded High Output 400 V8 L74, which boasts a compression ratio of 10.75:1, a more aggressive cam, larger exhaust manifolds, and an open air filter, all of which add up to a factory rating of 360 horsepower at 5,100 rpm and 438 pound-feet of torque 3,600 rpm. Sending output towards the rear wheels is the Turbo 400 three-speed automatic transmission, with a set of upgraded 3.90 gears added in the rear. Weight is estimated at 3,649 pounds.
Heading over to the other lane, we find a 1972 Chevy Chevelle, which is showing up to the party with the range-topping 454 LS5 V8 engine. Compression ratio is set at 8.5:1, with output coming in at 270 net horsepower (roughly 350 horsepower gross) at 4,000 rpm and 390 pound-feet of net torque (around 450 pound-feet gross) at 3,200 rpm. A four-speed manual is on deck for the cog swaps, while a set of 3.73 rear gears complete the package. Weight is estimated at 3,677 pounds, making the Chevelle roughly equivalent to the Pontiac GTO when it comes to heft.
Thing is, both vehicles compete in the Pure Stock Drag Race Series, which does allow a few modifications to be made. The question is, which of these GM muscle machines will walk away the winner? Hit play to find out:
