The two competition for this race are a 1969 Chevrolet Chevelle SS plus a 1969 Buick Gran Sports activity 400. This is a single-pass period trial race. Let’s have a closer look at the cars.

The Big Block is supported by a Muncie four-speed guide transmission and a Posi-Traction tail with 4. 10 back gears. The Chevelle weighs about 3, 895 pounds along with driver. Testing by Very hot Cars magazine in Feb of 1969 resulted in the quarter-mile time of 14. ’07 seconds at 101 kilometers per hour.
The particular 1969 Buick Gran Sports activity 400 is equipped with a four hundred cubic-inch V8 producing four hundred horsepower and 440 pound-feet of torque. The 400 includes a 10. 25: 1 compression setting ratio. Backing the four hundred is a three-speed Hydramatic automated transmission, combined with a three or more. 31 rear gear percentage. The Gran Sport suggestions the scales at a few, 812 pounds with its operater, giving it an 83-pound benefit over the Chevelle SS. Just 2, 024 Buick GS 400s were built for that 1969 model year. Unique testing by Motor Trend within January of 1969 created a quarter-mile time of fifteen. 9 seconds at 89 kilometers per hour, but this was completed with a convertible GS four hundred with a 2 . 93 back gear.

Very shortly, the particular Chevelle SS pulled forward, leading the GS four hundred by more than a car size by mid-track. The Chevelle SS continued to business lead the GS 400, however the GS looked to have already been reeling in the Chevelle DURE by the time both cars attained the finish line. The Chevelle SS finished with an past time of 14. 41 secs at 99. 6 kilometers per hour, versus the GS 400’s respectable 14. 63-second passed time at 95. sixty four miles per hour.
