[cld783]

looks like you got a pretty sweet deal.. do i see a gasket leak?

[87gtVIC]

you have no idea how much i hate you right now. anyone around me is selling those for more and they look like ass. errrrr. enjoy.

[Bowman85merc]

thanx mangs

Just don't get overwhelmed if it starts to give you shit.

yea i am waiting for it too, the car has just been sitting for 6 years, so it is expected to have crap go wrong on it

looks like you got a pretty sweet deal.. do i see a gasket leak?

yea, the one on the throttle body... hopefully it will be replaced soon...or if i can put an explorer intake on lol.

you have no idea how much i hate you right now. anyone around me is selling those for more and they look like ass.

yea the reason i got this rly cheap, i know like everyone at the junkyard so that helped alot...they also wanted $1500 before the dealing started lol

[Grand Marquis GT]

Want.

ok the problems have started, blew off all the mice nesting and did a full tune up and now we're getting no power to the r/gr wire going to the coil, my dad ran a jumper wire from battery to coil and everything comes to life and it'll start and run, we even jumpered one of the relays that we think is the EEC relay and that even allows it to start, but it'll stay running even with the key removed. we even tried to check for codes and that isn't working either. ran test light from battery to self test connector and the test light won't even light. and the test light does work.

[marquisman]

might be a bad fuse link or bad wire that you didturbed while cleaning

Very nice car, you even still have the Marchals on there. My best friend has really nice 92 LSC in the same color with a very light cream interior. She got it from neighbor of mine that kept it immaculate for years. You're definitely going to like that car. Very peppy and excellent handling for as heavy as they are. They can keep you busy, I just replaced the voltage regulator on her car the other day.

After you get the basic stuff fixed, I have a list of upgrades....

1. 3.73 gears, and do the 8-clutch mod to the stock limited slip diff.

1A. get the injectors professionally cleaned, off of the engine.

2. 2400 rpm stall convertor, non-locking.

3. Mustang off-road H-pipe, 2 1/4"

4. Custom 2 1/4" exhaust (Mustang cat-back requires a lot of modification to work, it's more like a T-bird under there, than a Mustang)...stock exhaust is dual 2".

5. Removal of the air silencer in the driver's side front fender.

6. Mustang TB to airbox hose....the MK7 unit is smaller.

Once you get all of that done, get back to me.

Beautiful car mang!!!

I had an 88 LSC a few years back, damn nice car, despite the buggy airbag system. I roasted a few sets of tires with it :3

[Bowman85merc]

well we found the problem.
When we were putting on the spark plug wires we moved one of the connectors, it was pulled like a 1/4'' out.

you even still have the Marchals on there.

whats a marchal ??? lol

After you get the basic stuff fixed, I have a list of upgrades....

could i just use the explorer intake, TB, and injectors ???
and im thinking 2-1/2'' exhaust
3:55 trac lok
and a cold air intake

and thanx again mangs !!!

1. Exploder intake, TB, and injectors? Yeah, if you have a set, throw them on, it won't hurt any.

2. 2 1/2" exhaust? Yeah, if you want to kill off all of your low end torque.

3. 3.55 traction lock? It already has a trac-lock in the rearend, nor are there any bolt-in replacements with 3.55's.
3.73 gears are the best set for this car, since it's a 4500+ pound tank. Go weigh it sometime, lol.

4. Cold air intake? If you want something rice under the hood that draws in hot underhood air, then by all means, put a rice cold/hot-air intake under the hood. For all intents and purposes, the stock High Output airbox, with the air silencer removed, and a K&N filter installed, will provide more than enough airflow to supply the HO motor. Just remember to replace that air inlet tube that goes from the TB to the airbox with a Mustang unit, as the Mustang flows more air (that's why there's a pinch in your existing tube, where the Mustang doesn't have one).

5. Marchal lights? The LSC's came with factory-equipped with Marchal driving lights under the front bumper. Usually they get knocked off 90% of the time, just due to where they are located, so it's an oddity to see them intact. These are the same driving lights that were included on the 1982-1986 Mustang GT's, and I think I have a leftover NOS lense for one...but don't quote me.

I'm not trying to tell you how to modifiy your car, but I have owned, been working on, and building modified 5.0 Mustangs (and related fox bodies, including the Lincoln MK7 LSC, T-bird, and Cougar) for the last 20 or so years, and know how to build a pretty damn quick Fox body (or variant) on a budget. In addition to my history with these cars, I have also been a tech moderator of the same Mustang forum since 2001, giving this same advice....over and over again.
One or two of the suggested ideas you have are going to make your AOD-equipped tank of a fox body run like shit, vaporizing whatever low-end torque you still have, especially if you try to run 2 1/2" exhaust on the car. You can't do the typical 5.0, 5-speed Mustang stuff on a car weighing a thousand pounds-heavier, along with that same car packing an AOD. Everything that has been done with the LSC from Ford was to maximize low-end torque on this car, hence the smaller intake tube and 2" exhaust (the Mustang has 2 1/4"), as the HO motor doesn't make as much low-end grunt, as low in the rpm range as a LoPo motor.

Basically....3.73 gears first, everything else later, as any of the proposed mods you suggest will make that car a freaking slug until it hits 40 mph if you don't touch the gears first.

traction lock was optional, you may or may not have one now. It was not standard, though many did have it. Stock gears are a 3.27, and honestly its not that bad. Mine has more balls with its bone stock HO than my Towncar has with 3.55 gears and other mods.

[Bowman85merc]

since it's a 4500+ pound tank. Go weigh it sometime, lol.

yea i noticed that on the title...i cant believe it can be that friggin heavy in this little package lol

hey gadget, i see ur a memebr of the LincolnsOnline club to lol. very nice car mang.

oh and i read the TurboCoupe front sway bar or sumthing would be an upgrade, is that true, because theres like 2 at the junkayrd and 1 supercoupe.

...soo everything i thought of would = FAIL basically...and it would accually make it worse than it is ???

but would the explorer intake, TB, and injectors be a good addition...or equal FAIL like everything else.

and the cold air intake i was thinking was a fender unit one...or a ram air style that goes under the bumber.
and yea i took off the air-intake tube, thats like a 1'' hole lol, i cant believe it can even breathe lol
and i did see that air jug silencer thing, it will be removed tomorrow or sumtime

so 2-1/4'' piping eh? well yea, i guess with this much weight u do need torque to move it lol

and im guessing 3:73's arent cheap...do u have any prefered place to buy them from ???

so what about underdrive pulleys and stuff like that, would that help, or be FAIL also ???

and yes this is on a pretty tight budget...but i need help to make it go faster lol.

[gadget73]

Turbocoupe front bars yes, Supercoupe is a different chassis.

You can do upgrades, just keep in mind its a tubby car and it needs torque. What works for a 3000 lb Mustang doesn't do so well on a 2 ton LSC. Big exhaust on a small motor will sap some torque. Explorer intake works for an upgrade over stock, but I would agree with keeping the stock airbox. Performance wise, it works quite well even if it doesn't look cool.


My LSC is actually bone stock, and it moves very well. My plans involve new 2 1/4 catted exhaust, my P heads, the 1.72 rockers if they'll fit under my stock valve covers, and probably a ported stock intake. It won't be a rocket but it should move better than it does now without screwing with my fuel economy. I appreciate the fact it does 20 mpg or better on the highway. I know I could get better results with more gear, but I'm fairly happy with how it performs now with boring gears.
