    Got the Grand Marquis from my Grand Father when he passed. Was going to sell it but I like it and decided to keep it and modify it a little. He was a car guy, Ford in particular, and had a 1969 mustang and a old Ford 30's hot rod. I was a Chevy guy, him with his Fords. I think he'd get a kick out of me hot ridding his old daily driver. Looking forward to the project and sharing ideas with everyone here. The car drives fine except for early shifts and a late overdrive kick down (25mph). (After a few weeks of driving I read on here about the TV cable bushing and checked it, it was gone and cable was not attached. No idea for how long. Installed a brass bushing and manually adjusted cable.) All I did so far is put LED lights in all around, sequential rear turn signal kit and a aftermarket stereo. My plans are: MAF conversion, GT40 intake and heads, trac-lock (has 3.73 open now), rear sway bar, some suspension work and maybe a cam, and a complete dual exhaust with either shorties or long tubes and either X or H pipe. This is my first Ford. Feel free to point me in a direction. This car will kind of be a tribute to him. I already set the timing at 14 deg. and just that alone gave it a little more spunk. Except it pings under load without 93 in the tank. I'll continue to observe while I read ya'lls posts and make my plans. Have a great week and keep your grille out of the bushes.

    Welcome!

    What year grand marquis? I have an 87 myself. The reason for early overdrive is that it has steep gears, they’ll cause stacked shifts. Its exacerbated by the LoPo governor causing the trans to shift early. Even at wide open throttle it shifts around 4200 rpms from first to second with a stock governor. You’ll need a tune or a mustang ecu if all you want to do is a HO swap (86-95 mustang high output motor) but if youre planning on a big cam Id suggest finding a local tuner.

    If you do a MAF conversion i assume you'll be going to HO firing order with a mustang computer. That opens up a world of possibilities cam and other stuff-wise. If you're running a MAF setup it'll be ok without tuning, although obviously a tune makes it better. You would likely have trouble making longtube headers fit but mustang shorties go right in. I lightly modded mustang midpipe will also fit and get you well on the way to a good exhaust system. The downer now is that walker no longer makes the tailpipes we use on these things. If you have a good local exhaust shop they can probably bend you up some pipes though.

    Far as gt40 heads go, unless you have access to a REALLY cheap set, save the money and buy something better. There are so many good aluminum heads out there and things have gotten so cheap. I've personally bought 3 sets of good aluminum heads for $800 a set. Used, of course but one set was fresh out of the shop, the other 2 extremely minimal usage. Anyhow, glad you're setting out to mess with grandpa's car, that is way cool and we look forward to seeing/hearing what comes of it. Welcome!

    Ooo sequential tail lights... my favorite. Definitely got an advantage since I can’t do that with my wagons.

    Enjoy the ride!

    Thanks everyone. The car is a 1990. Arizona bought and raised. Been in Wisconsin for 4 or so years. Brake and fuel lines are still rust free. I picked up a 1997 Mountaineer 302 with a blown trans shortly after my post so I'll use that for my GT40 swap. Aftermarket heads are what I would have done but I want to do it as cheap as possible and use somewhat stock parts in case I need something later. Both engines look almost identical, wondering if I can just swap in my distributor and some other little do-dads and put it in My Grand Ma? The Mountaineer runs so damn good... Burn outs in 1st gear for days. Lol. Right now I'm gathering as much as I can before attempting to do any work. I get easily distracted and confused if I take too long to do something. Also, the MAF mod is worrying me. I don't like leaving wires and sensors in there that wont be used. I did the Big 3 wire mod and put in a higher amp alternator out of a Taurus and the dead wires are driving me nuts. lol. It will be a slow process but I'll try and document it as much as possible and post it. Thanks in advance for any thoughts. And don't be afraid to tell me if I'm screwing something up. Oh, and I chose a paint color: Chrysler Destroyer Grey. I love that color and think it would look good on it. Goodnight.

    No, Ebay plastic bag China special. Lol. But they work nice and were easy to install.

    Also, found an H-pipe from a 1990 TC for $64 on RockAuto. Ya'll know if it will fit GM's? Everyone is out of direct fit pipes. I already bought single chamber mufflers and the rest of the exhaust including new cat setups. I started pulling the motor and wiring out of the Mountaineer yesterday. I am not going to port anything. Just clean the heads and intake up, have new valve seals and springs installed and have head resurfaced. I want to keep everything under $800. Still have to locate a trac lock or axle. I'm going to do some research of how interchangeable 1993+ parts are since those cars are the only ones I can find. Slight modifications are no problem.

    Ive been told the town car h pipe is longer by a few inches. I shouldve compared mine to my y pipe before I installed it to see how much of a difference it really is.

    I'm running a '90 Town Car H-Pipe and mufflers on my '87. Had the tailpipes welded onto the back of the mufflers, but everything bolted in without much fuss.

    Ok, I really apologize for asking but I have been looking and can't find an all inclusive guide on the GT40 swap. I really don't want to take bits and pieces from several posts to do this job. I want to do it right. The MAF mod I think I can do, I bought a California equipped MAF sensor from RockAuto for $40 that bolts to the TB (Along with a 1989 T.C. H-Pipe that fits great for $63) and will use that as long as it has the proper fuel mapping. I found an A9P ECU. And I have a 3:27 open 7.5 and want to swap in a trac-loc unit. I need a list of candidates to snag the carrier from. My 97 Mountaineer is a 8.8 trac-loc so that wont work. I'm not looking for all the answers, just point me to a direction so I can get the info. It's out there, just can't find it. Thanks.

    For the traction-lock, you need a 28 spline 8.8 donor. Your car will have an 8.8 already. Most common traction lock donors are 90s-00s 4.0 Rangers, V8 Mustangs 86-04ish, and the unusual Panther here or there 83-04ish. You will have to check the door tag or better the axle tag to be sure. Axle tag should have the ratio with an L between, 3L55 vs 3 55 for open. Best case is finding a complete Panther axle up to 97 that you can swap pretty directly and not have to deal with the differential guts.

    I am no help on the MAF.

    Thanks for the info Mr. Tiggie. That helps alot. Idk why I thought I had a 7.5. My axle code is 5. I'm just gonna try a carrier for now. Your info gives me a good place to look. And axle swap is a great idea and def. will do once the engine is done. I am going to make my own rear control arms. I've made several for ATV's, shouldn't be too different. I was wondering where this clunk kept coming from, changed engine / trans. mounts and still there. Turned out to be the control am bushings. Was gonna do the bushings and was sad to see how flimsy these things are.

    If you bought a MAF for a crown vic it'll be tiny and also meant to run 14# injectors. If running an a9p, you'll want a stock or aftermarket MAF for a fox mustang meant to run 19# injectors, which is what should be on the Exploder/Mountaineer engine.

    Thanks for the info. That is what I bought. So the MAF sensor from the 97 Mountaineer will work? And use the Mountaineer injectors?

    problem with making the arms very stiff is the rear suspension is more likely to bind up. The arms aren't parallel, and it needs some slop and flex in order for it to all work right. Make everything rigid and the rear can bind in travel or it might just rip the mounts off the frame. Honestly if you want to keep the rear under the car, fab a panard rod for it. Or see if you can retrofit the Watts link from a later one. Either will keep the axle where it belongs.

    You want the MAF that goes with the ECM you are running, or you want some means of tuning the ECM to the MAF. You can run any mix of parts you like so long as the ECM is programmed to the MAF transfer curve. The MAF has not a thing to do with the injectors though. Thats a common bit of BS from the Mustang world. The ECM has a set of parameters that match up to an injector, and the ECM has a set of parameters that match up to a MAF. The "calibrated" MAF sensors you might hear about feed a modified signal to the ECM to trick it into running a different size injector. Basically it lies about the amount of air going in, so the ECM sends the right signal to the larger injectors so they work anyway. Its a bad way of making stuff work together.

    anyway, the A9* is tuned for whatever injectors were in the 80s Mustangs, but they will work with any 19# without much fuss. Mountaineer injectors should be fine so long as they plug in. The tripminder (if you have one) may be somewhat wrong though.

    What cam are you running? The stock Mountaineer valve springs are pretty useless for anything besides that stock cam. The truck cam pulls nice but its done with by about 4500 rpm. An HO cam or really anything else will have more lift and run more rpm than the springs are going to control. There is a Trick Flow part number somewhere on here that is the usual suggested item.

    you'll need a Lightning EGR spacer in order to mate the throttle cables up properly. The Mountaineer throttle body needs the lever swapped from your stock throttle body as well.

    need the oil filter adapter. The oil cooler doesn't fit, and without the cooler you've got nowhere to screw the filter. Part number is on here somewhere, but its the same part used on basically every Ford V8 from the early 60s through the mid 90s. Basically it looks like a pipe nipple.

    Oil pan and timing cover come from the existing engine or are replacements for it. Same as 80s Mustang parts. water pump is for the Grand Marq.
