There’s no shortage of performance models when it comes to GM’s past, with a long list of iconic nameplates to choose from. Now, we’re watching two of these GM go-fast machines duke it out on the drag strip with the following racing video between a Pontiac GTO and Chevy Corvette.
Clocking in at about six minutes, 30 seconds, the video comes to us from the Cars And Zebras YouTube channel, and features all the usual C&Z elements, including a walkaround for both vehicles, specs and history, and some racing action. For those readers who want to jump straight to the drag strip, skip ahead to the three-minute, seven-second mark.
With that all covered, let’s take a closer look at the competitors, starting with the 1969 Pontiac GTO Ram Air. Under that Ram Air decal on the hood is a 400 cubic-inch Ram Air III V8 engine, which sports a compression ratio of 10.75:1, and output ratings of 366 horsepower at 5,100 rpm and 445 pound-feet of torque at 3,600 rpm. Sending that muscle to the rear axle is a four-speed manual transmission, which feeds a set of 3.90 gears. Curb weight with driver on board is a relatively heavy 4,034 pounds.
The next GM machine in this matchup is a 1973 Chevy Corvette 454, which is showing up to the party rocking an upgraded LS4 454 cubic-inch V8 engine good for a factory-rated 275 horsepower at 4,000 rpm and 390 pound-feet of torque at 2,800 rpm. Compression ratio comes to 8.5:1, with a three-speed automatic transmission on hand for the cog swaps. A set of 3.08 gears are in back. Curb weight with driver is set at 3,945 pounds.
Notably, both the Pontiac GTO and the Chevy Corvette run in the Pure Stock Muscle Car Drag Race series, which does allow for a few modifications. The question is – which will come out the winner? Hit play to find out for yourself.
