Dyno Results
Here are the results! The factory horsepower and torque ratings for this 1985 GT were rated at 210 HP and 265 lb/ft of torque. Our initial dyno pull with the OEM carb produced 185 horsepower at 4500 RPM and 249 lb/ft of torque at 3500 RPM. After swapping over to the new Holley carb, this 5.0L made 192 horsepower at 4500 RPM and 251 lb/ft of torque at 3600 RPM. By no means necessary were we shooting for a night and day difference here. We wanted to highlight that there are still aftermarket options you can basically bolt-on in your driveway without substantial modifications.
