We had a cool collection of cars and “truck” show up for the Shelby Club Dyno Day this morning. We kicked off at 8am with hot coffee, donuts and an adventurous straight-six 4.0L Jeep. We’re always amazed at the way large diameter offroad tires float. It’s a good thing the Jeep has a 90 mph speed limiter! Dyno contenders included a 428-powered ’64 Galaxie with a sticky throttle, a drag race ’62 Ranchero with 5.14 gears and a narrowed rearend that barely fit on the dyno. It was motivated by a high revving 363 ci small block. We also dyno’d a 402-Roush powered ’65 Superformance Cobra, a 2003 Mach 1 Mustang, a very clean ’66 Mustang Fastback with a stock looking engine that was anything but. Try a 366 SBF that laid down 337 rwhp. Next up was a 2003 Mustang Cobra that featured a 2.93″ pulley and custom tune. Terminator’s always seem to need more than one trunk monkey to hook up! We also ran an 8.0L ’94 Viper, a supercharged ’94 Lightning and we wrapped things up with the 2012 Vortech-supercharged JBA Boss 302. Oh yeah, somewhere in there JBA grilled hot dogs and broke out cold soda pop. All in all, a fine time was had by all. No one blew up or broke!!!
