1969 Chevelle SS vs 1970 Buick GS 455 Stage 1 - PURE STOCK DRAG RACE (best of 3)

1969 Chevrolet Chevelle SS 396 375hp L78 vs 1970 Buick GS 455 Stage 1 (Pure Stock Muscle Car Drag Race)
How about these two cars!?!? RIGHT!?!? Arguably, my favorite Chevelle and my favorite Buick GS. Of course the first car is a 1969 Chevrolet Chevelle SS396 L78. And that L78 is an absolute monster! Rated 375 horsepower, but come on, there's definitely a lot more hiding under that hood. Seeing the build sheet is really cool. To me it's pretty obvious that the original buyer wanted a car to go fast, and that was about it! Around that time the L78 was a pretty good deal.
Then we have its competitor... that being a 1970 Buick GS455 Stage 1. Yes, a Stage 1. One of the most nasty torquey cars out there. Only the absolutely massive 500+ci Cadillac engines of the day could match that torque. As you'll see in the video, Motor Trend tested this car in 1970 and it was quicker in the 1/4 mile than a 1970 Hemi 'Cuda! Pretty crazy. Which car do you like more?
