    I am in the process of restoring my 1985 mustang GT EFI AOD and require the engine Decal That's located on the engine. The only ones that are listed are for Carb/manual ? or 1984. which is EFI AOD. So if anyone could advise where I could obtain one for The 1985 model?

    Red78' and FoxChassis have portal aceses to the Calibration tag details. Cross chech posts on 6-25 of this year. LMR might sell them.

    Another link is related to earlier Foxes. Im on touch screen cell phone away from my desk top, so I can't screen dump all the links, but Red78' and Fox Chassis weighed in on Darrans Blue Bomber resto and it explains things even better.

    Thank you for that it expands on what I have already been able to find, That the tag would be in the YK340AA/BB/AB numbers.
    I will post some pictures of the undercarriage as I was lucky that being a California car it cleaned up as new and so far all the paint markings are still able to be seen right down to the spring tags etc.

    It’s been a while since I looked into it. I believe there are about 4 different calibration codes for the 85 efi. 2 for CA. Basically, ho or not ho.. it’s all in the Ford parts book.

    The M codes were either Carbed T5, or Central Fuel Injection with AOD, trans code defined

    induction system,
    ignition system
    exhaust catalyst arrangement
    and camshaft type.

    5.0L/AOD 5K340AA (DSO missing from build sheet -- unknown emissions)
    5.0L/AOD FK340BB
    5.0L/AOD FK340CB
    5.0L/AOD FK340CB (SSP)
    5.0L/AOD FK348BB
    5.0L/AOD YK340AA (CA emissions)
    5.0L/AOD YK340BB (CA emissions)


    Any same year engine can be placed in an Auto AOD CA, but it had a dedicated intake, TFi ignition, one less catalyst without the flapper valve for preheat, and flat tappet Hydraulic cam with special cam gear. The CA emission package is probably more a priority change for the Thermactor, and possibly the exhaust headers and converts and non convertibles had differences in header type. the rocker covers may have been downgraded to pressed steel black painted items on CA engines. Ford being Ford, its hard to say.

    The later 85 CFi 's have a different ECM EEICIV batch code, with different control to the earlier 84-1/2 CFi's. The 02 sensor earth is in the ECM.

    So the O2 sensor earth changed too, with a change to a single tank fuel pump. Early ones had a two stage twin pump with one pump external. Yes folks, Ford changed everything, without notice...often.

    http://vb.foureyedpride.com/showthre...I-Valve-Covers
    Black rocker covers, see JA Cookes 85 CFi engine below.The mid-'85 CFI cars used fuel system components brought forward from the '86 model year. Not just the wet gear for the EFI, but rocker covers were being experimented with.


    ....the last CFi's were running the begining of the Port EFi crank case ventilation system. The old Y pipe was gone on the CFi engines, so it was easier for another set of cheeper rocker covers to be phased in. The computer was using most of the sequential wiring for the O2 sensor, and the CFi was getting more removed from the 4V 5.0. Not even the LSC matched the CFi's new found GRUNT. 180 HP of Pirate color rocker Ford, yarrrrrr.....!!!!!

    A few years back I did a mockup of both styles that shows the differences. The mockup was done using
    the original block and heads from my '85 Vert, and new factory-issue convertible-specific engine mounts.

    The 4-3-1 headers are original to my '85 Vert. The 4-into-1 headers are the original ones from my '85
    hatch.

    First, the 4-into-1, passenger side:

    Likewise, the driver-side 4-into-1:




    And finally, the driver-side 4-into-3-into-1:

    Default decal information

    That information narrows it down further, my mustang is 5/1985 GT HO build single fuel pump will have to check out the wiring to the ecm and the other items mentioned. it's been a great help. I have had the car since 2002 so every thing is in boxes and tagged plastic containers.

    Thanks for that`
