When I installed the motor, I had it dyno'd at 317hp off the motor. With the current intake, injectors, and exhaust (Utah smog legal emissions), it's down to around probably 260-270hp. But....We still eat a lot of Mustangs and Camaros for lunch! The main problem is hooking up to the pavement since the ride height, wheels/tires and a lot of the suspension remain stock. It's just an old T-Bird to most people when they see it....until the tail lights fly by....and that's where the fun is!
