Is this a 5.0?
Yes
Use the heads you have. THe Towncar Fuel injection system is of the SO variety (read: 14 pound injectors). Take the intake, rails, and EVERY stitch of wiring harness and sensors and of course the throtle body and air tube. Your current cam will have the same firing order as the Town Car cam except the Town car cam is a roller cam. You can use the injectors and computer from the Town Car if you just want to get the EFI up and running, but don't expect a monstrous increase in power (if any).
the wiring harness isnt a "bolt-in" for fox cars. the computer is mounted on the driver side underneath the dash by the brake pedal. i tried using that harness years ago, but it was too much work.
You already have better heads, the '86-up SO 5.0 uses the infamous E6s...
None of those parts are good for making power...
