Re: 4.6 and 5.4

isn't the lightning a 4v? If so, you will require 4v heads. Which means a lot of the interchange parts will be for the Cobra motor, not the 2v GT motor.

Re: 4.6 and 5.4

the lightning motor is actually a 2v motor, the 4.6 heads will bolt up with no problems. there are no production headers made to fit the 5.4 motor in a mustang, u can get shorties and make them work with a little modification to the mid pipe. the heads are pi heads on the lightning, any aftermarket heads that bolt up to the 4.6 2v will go on the 5.4 2v. however the intakes will not swap over due to the difference in width between the 2 motors. all electronics will bolt up fine.

96 GT- Who knows what's in it.
