The Crown Victoria Aero 4.6 swap project... I swap the 4.6 Dohc Aviator motor with Mach l upper and lower intake... I am running this off a Stock 96 4.6 2v engine harness ( thus why the trouble ) and I add a 5 speed swap. One min the car runs fine and another it can not even rev.. There is so much in the video please give it a look see..
