This Mustang started out as a humble S550-generation GT with a 5.0-liter V8 engine producing 450 horsepower and 420 lb-ft of torque. After a lot of wrenching, testing, and tuning, her Mustang eventually ended up housing a 9.8-liter big-block Ford V8 engine mated to a Tick Performance T56 Magnum XL transmission. Additionally, it’s blown to kingdom come in a fashion that would make Dominic Torreto proud.
In a previous video, Hartford had the Mustang dyno tuned. At the tuning session the car made over 850 horsepower with little to no effort, but what was even more impressive was the torque figure: this beast made over 1,000 lb-ft at just 3,000 rpm. Later in the video, Hartford reported that they were experiencing issues with the engine related to the valve springs. Rather foreboding wouldn’t you say?
