By the time this reaches your mailbox or newsstand, it will be the hottest time of the year. As little as most Fox-body owners care about A/C, summer time always makes you wish you had it-especially if you live in a hot climate like we do. Maybe you disconnected it during an engine upgrade, or ditched the compressor for an A/C delete pulley like we did on our SSP in “Lifting Weight” (June ‘10). Either way, you may be surprised how little money and effort you need to spend to get the snowflakes blowing out of your vents again.

For those of us who’ve been around the block a few times I’m sure you remember hearing about the first 5.0L EFI Mustang engine swap into a classic Mustang. Maybe it was in your favorite magazine, or perhaps you walked by a nice Mustang at a show and had to do a double take when you looked to see what was under the hood. Regardless of where or when you first saw this swap, probably the first question you had in your mind was “how hard was it to do?”, followed quickly by “I wonder how much it cost?” Well, depending upon when you saw your first 5.0L EFI engine swap the answers could be “it was a pain in the butt” or “it was as simple as plugging in a few wires.” Reason being, early adopters always have it rougher. These fanatics go on a fact-finding mission, tearing into the project with abandon, buying up wiring diagrams and learning how every little subsystem works. So if you saw your first 5.0 EFI swap 15 years ago, it meant it took that owner a lot of trial and error, custom wiring, and fabrication of parts. Today it’s mostly a matter of which company do you want to buy your conversion wiring harness from (there are at least four that we know of) and how you’ll setup your fuel system. Yes, it has become that easy to install a 5.0L EFI engine into your Mustang or other classic Ford. Hell, there are whole companies that survive off of manufacturing swap parts and doing the conversions.inline_mediumwraptextrightThe 4.6L Three-Valve Control Pack, shown here, includes a custom-calibrated PCM, a chassis side harness (you reuse your engine side harness), Ford Racing cold air induction kit, ETC throttle pedal, Ford Racing mini power distribution block (PDB), a mass-air meter, and new oxygen sensors. The 5.4L Four-Valve kit also adds supercharger-specific cooling hoses and fittings as well.28089916/techarticles/mdmp_1004_modular_engine_swap_wiringmdmp_1004_01_+control_pack_chassis_harness+three_valve_control_pack.jpgTrue
