Here are the results! Hubbard's Shelby produced 254 horsepower at 6000 RPM and 271 Lb/Ft of torque at 3300 RPM. We backed this run up with a second pull with the air cleaner removed and the exhaust disconnected. On this second run, we made 269 horsepower at 6000 RPM and 276 Lb/Ft of torque at 4200 RPM. The netted peak gains of 15 HP and 5 Lb/Ft of torque. Not too shabby for a car that was made well before some of us were even born!
