1971 Plymouth Cuda 426 Hemi drag race 1969 Chevy Camaro ZL1
Jordan Pennington's 1969 Camaro ZL1: • Stock Appearing 1969 Z...
First car is a 1971 Plymouth Hemi Cuda. The other a 1969 Chevrolet Camaro ZL1. The Hemi Cuda of course features a 426 Hemi V8. The Camaro has an all aluminum ZL1 427. The Hemi Cuda was rated 425 horsepower stock, and the ZL1 430 horsepower...both very underrated. Both cars feature automatic transmission. The Hemi Cuda has a TorqueFlite 3-speed automatic, while the 1969 Chevy Camaro has a TH400 (Turbo 400). Rear gearing is unknown for both cars. Curb weight for the 1969 Chevrolet Camaro ZL1 is around 3500 pounds, so it has a weight advantage over the 3721 curb weight of the Hemi Cuda. The Hemi Cuda option was expensive, running around $871. However, the ZL1 option was a whopping $4160!! There were only 69 total 1969 Chevy Camaro ZL1 produced, and even less 1971 Plymouth Cuda Hemi automatic equipped cars at 48. Original testing of the ZL1 by Hi Performance Cars magazine in 8/1969 with a completely stock car netted 13.16 seconds @ 110 mph. However, only 3 months early Super Stock magazine used the same car, threw on a set of open headers and 6.5 inch wide slicks, and ran 11.64 seconds @ 122 mph. The 1970 Hemi Cuda was assessed by Cars Magazine and ran the 1/4 mile in 13.45 seconds @ 115 mph...but that was a convertible with an automatic transmission and 4.10 gears.
Remember, both cars participate in the FAST (Factory Appearing Stock Tire) series of drag racing. Please visit their website. www.fastdrags.com
