Yeah..i know its huge engine...very wide. I know of at least one cobra, and ffr, that has a 4.6 dohc in it. I remember reading that it fit fine after mounts were made but that the wiring and computer were a headache. This was s few years back...so maybe its different now. I have read something about JBL's working on fitting a modular motor so that should be pretty damn cool when its finished. I also see on HDR site that they have pic's of both a cobra 4.6 and a lightning 5.4 under the engine options. The prices on the mustang site are outrageous for the most part...i thought the MACH 1's were priced pretty good though. THe 03' is under the "parting out" section...its a salvage. You could also get the IRS, brakes, and other goodies out of that sucka too. Man all this talk has my mouth watering to buy a cobra..but I've given myself a year to wait and save up. I'm thinking of a JBL with a stroked 498in small block
