    Default LTDMan's '87 Mercury Grand Marquis LS (Big Red) *DUW*

    Here is the most recent and permanent addition to my car collection. Acquired from a local GMN member (87mercman).

    a 1987 Mercury Grand Marquis LS, nicknamed "Big Red" by her former owner.

    Built at the St.Thomas assembly plant in Canada, and then shipped to Cloverleaf Lincoln-Mercury in Decatur,AL in 1986. Were she was Originally sold to the grandparents of the guy that I bought her from (87mercman). She is allmost fully Loaded, and originally sold for $18,193 according to the window sticker sheet. The car is factory painted Midnight Canyon Red Metallic, with a Canyon Red Velour Interior. Big Red has 205,744 miles on her as of today.




    Current Mods: (All these mods were performed by the previous owner(s).

    -Engine transplant - 5.0L HO (from a '91 T-Bird)
    -Mass Air Conversion using a Mustang A9S ECU & 70mm MAF
    -Injectors replaced w/ new Ford Motorsports 19lb'ers
    -Stock air-box replaced w/ a WAI & K&N cone filter
    -1/2in" intake spacer
    -Dual Exhaust w/ stock 2in H-pipe/ Hollowed Cats/ & Imco Turbo mufflers.
    -Aftermarket 1.25in" Rear Sway Bar installed
    -Coil-Over Towing Shocks installed in the rear
    -Voltage, Oil Pressure, Coolant Temp, and Tach Gauges installed
    -AOD rebuilt (58,612 miles on it since the rebuild)







    Here she is loaded onto the Ford F-350 Roll-back that helped me to save her. Just like last time, a Ford helping to save a Ford. Only cost me $70 in Diesel to get her back to my place.




    Big Red's Current Condition. The paint has been sanded off the top of the car, primered, and is now starting to rust in some spots, but as most of you know I'm in autobody work, so doing bodywork/painting a car at anytime is not a problem for me. The body is Straight, with no accident damage whatsoever that I can find. Big Red has been a southern car it's entire life, and is amazingly Solid. Easily 98% Rust-Free on the Rustification scale.












    Stock LS Interior, in Red Velour. Was partially disassembled when I first got the car. At this point I have only re-assembled the door panels/dash trim, cleaned out all the trash, and gave it a quick vacuum job. The interior is in decent shape, and something I can definitely work with. I will be fully restoring the stock Interior in this one.











    While the DS door panel was off, I went ahead and replaced the dead Power Window motor, with a Fully Rebuilt one. Had to lengthen the wires, as this motor was meant for the PS rear door.




    5.0L HO Engine from a '91 T-Bird, has also been MAF Converted, using a Mustang A9S ECU & 70mm MAF. According to the maintenance records the engine had 45K miles on it when it was installed in this car, and the car has been driven 68,789 miles since the engine was installed, so all told this HO engine only has around 113,000 total miles on it. Which means it still has quite abit of life left, before it will need to be rebuilt. Still has the stock lopo Upper Intake/EGR/TB and Exhaust Manifolds, which I will be replacing with an HO Upper Intake/63mm Bored Box EGR/Modified Mustang 60mm TB. I am probibly gonna go with Ceramic Coated shorty headers, instead of the stock mustang HO units.






    Nice, Rust-Free Undercarriage and Floorpans, just how I like em. Only a light coating of grease and dust on there.



    100% Rust-Free PS A/C Drain Bulkhead, common to southern boxes.



    The Dual Exhaust is nice and tucked up against the undercarriage, and can't be seen while looking at the car from the side, which is how I like it. I will be keeping all of this, and adding custom 2 1/4in tailpipes. If someone had just thrown a low-hanging Mustang Exhaust on there, it would be getting cut off right about now. The 4 stock cats are gutted, and I will be keeping at least 2 of them as part of the exhaust system, no matter what upgrades I may do, as this car will be a DD.





    Coil-Over Towing Shocks.



    Aftermarket 1.25in Rear Sway Bar








    Big Red's former owner Chris (87mercman), wanted the car to go to a good home, and didn't really care about the price, so he was nice enough to sell me Big Red for only $50, and with a few extras in the trunk as well. I especially appreciate the (very clean on the inside) HO Upper Intake, and low-mileage Trac-Loc Unit. I will install the 4in Alpine speakers in Big Red's front doors and dash, as well.









    Nothing really spectacular will be going on with this one, I will basically just be restoring the car to Nice Condition, doing a few mods, and then Daily Driving it once I'm done.

    Things I will be doing to the car:

    -Maintenance & Repair
    -Complete Interior Restoration
    -Replacing the lopo Upper Intake w/ the clean Mustang HO Upper Intake (which came with the car)
    -Installing the Trac-Loc Unit (which came with the car) (keeping the stock 3.27 Gears)
    -Installing an HO Governer or Shift Kit
    -Installing Shorty Headers
    -Installing Custom Fit 2 1/4in Tailpipes
    -Replacing the Entire A/C System
    -Installing a complete Audio System
    -Tint Windows (As dark as I can legally get)
    -Slicktop Conversion
    -Re-aligning all the Body Panels for better fit/closure
    -Lots of Bodywork
    -Full High End Re-paint, the stock (Midnight Canyon Red Metallic)
    -Drive the Hell out of it.




    Big Red is currently comatose at the moment, so I will be bringing this car back from the dead, hopefully very soon.


    Stay Tuned...

    That car has a very good home now. For some reason I see it in flat black with black vinyl dyed top. It'll look good red too.

    I (as the prior owner) second all those opinions and couldn't be happier for Big Red right now. I'm convinced she's in good hands and can't wait to see her looking spectacular again!

    Thanks Guys, the progress should go pretty quickly with this one, as I'm not trying to make it absolutely perfect, just to restore it to nice condition, get it running great, and drive it. It should be a pretty fun car to drive daily after I get it running right, and upgrade a few things.

    She is still Comatose right now, as I still need to buy a Battery and a TFI Module, which will cost around $160 together. I have also been slacking lately as far as working on my cars, because of the winter weather we have been having. Working in 15*F temps kind of kills my motivation, lol. I'd imagine that she is gonna run a little Rich though, due to not being able to get enough air through the lopo upper/TB, and old/failing O2's causing the ECU to dump fuel.

    Yea, I really didn't wanna be dragged off to Gatlinberg last weekend, but it was one of those family things for her, and she Really doesn't take no for an answer when it comes to me going to those things with her, lol. Hopefully the next time you are traveling through NC on a DX I will be at home, and we can hangout for awhile, cruise some of the local spots, etc...

    Default Big Red Lives Again!

    After installing only a new Duralast Battery & Positive Cable, Big Red fired right up on the first crank! The HO sounds great, and I can't hear any strange noises coming from the engine anywhere throughout the RPM range. Only problem now is that the engine will not idle, and will only stay running if you keep the throttle at least 800-1000rpm, which I suspect will be a bad TFI Module (which is what 87mercman also suggested). The next free day I get, I'm gonna change out the TFI module, and hopefully she will idle then, so I can take her for a short ride afterward.

    Stay Tuned.

    Just replaced the TFI Module after work tonight, and now she will Idle, only very irregularly and will stall out eventually. Runs and sounds damn good though.

    Slightly aggravated at this point about the idle issue, I was planning on ripping into everything full-force this upcoming weekend, and figuring it all out, when I logged into GMN tonight and noticed I had a PM from 87mercman. This is one of the benefits of staying in touch with the previous owner of a modified car.


    One thing to note that your recent post just reminded me of, and that I thought I should definitely give you a heads up on so it doesn't worry you when you go for the first drive...

    When I did the ECM swap out, part of the pin outs that you were supposed to add was one for the VSS since the HO mustang ECM typically came from a 5-speed. The one in Big Red is from a 5-speed, and I never was able to find the wire on the Speed Sensor that I needed to tap into for that set of data. The ECM works and manages everything just fine, except as I explain below for the occasional stall, especially right after disconnecting the battery.

    What will happen is this, the first several runs after clearing the ROM on the ECM (ie disconnecting/replacing the battery cable) the car will idle weird and when you go to drive, she will drive fine until you start to slow down. When you get almost to a stop she will stall unless you keep feathering the gas. This is due to the ECM looking for a cue from the speed sensor as to the deceleration rate.

    After you run for a few times the computer builds into its ROM that it should essentially not look for/ or ignore the "faults" from that data. This could easily be remedied by adding the pin to the ECM connector. If you need any assistance as to what this entails I still have all my research compiled and can send it your way.


    Thank you, as I literally could have spent 100's of Hours, and Dollars, trying to figure this out, and probibly would have never thought to check if the ECM connector harness was missing the wire/pin for the VSS signal, lol.
