Cars And Zebras's video: 1967 Impala SS 427 vs 1964 Studebaker Challenger - PURE STOCK DRAG RACE best of 3

1967 Chevrolet Impala SS 427 vs 1964 Studebaker Challenger R3 supercharged (Pure Stock Muscle Car Drag Race) Our first car is a 1964 Studebaker Challenger R3. The second car is a 1967 Chevy Impala Super Sport 427. The R3 was packing a 9.5:1 compression ratio with a Paxton Supercharger putting out 6 PSI at just over 5000 RPM. That translates into 335 horsepower... but these engines can easily rev over 6000 RPM, and even near 7000 RPM. You know what that means? Just over 400 horsepower when you hit that 6K mark. VERY impressive. The other car uses just pure brute force to motivate itself. The car is 1967 Chevrolet Impala SS 427. This isn't the high performance L72 that had 425hp, this is a more tame 385 hp V8 with 2 bolt mains. Don't let that fool you, this car can move! Unfortunately, that specific Impala was having major clutch issues come game-time. During time trials he qualified at 13.56 ET, but as you can see he was plagued with problems in the best-of-3. I'm sure all of you who have actually drag raced before will understand. It's rare that an old car runs perfect every time you hit the track.
