    Well, the wife got to drive it for the first time today. I was finishing up the steering rack replacement in her 850 wagon and she needed to do the weekly grocery run. She seemed to enjoy it, and I think she'll get a better handle on it as she drives it more. I also teased her that it was 4 years older than she was .

    I don't name my cars, but she does. She has dubbed this one "Natasha", as in the Black Widow. I'll allow it.


    I decided my plan for the rear suspension on this thing. I'm grabbing another set of Mustang rear control arms and modifying them. Going to box them and install poly bushings. I'll also replace the axle ear bushings with new rubber pieces. I'm also going to do the "anti-squat" mod to the RLCA mount at the axle. This will also bring the rear end down just a touch.

    Another task on the to-do list is a power steering fluid transfusion. Just need to pump some of the crud out of it. Steering assist seems fine, but is a bit "stiff".

    Been doing a little "bench racing" for a possible future engine swap for this thing.

    The plan for this car is for it to be driven and enjoyed. We're not doing any kind of concourse restoration on it and not really beholden to keeping it "original".

    Mentally, I think I've settled on the 3.7 NA V6 for it, and keeping it an auto. I know everyone gets a chub for a 5.0 Coyote swap (which are cool), but that extra power (and expense) isn't really needed for this car. 305hp and 30mpg sounds like a good option, if you ask me. Especially coming from the anemic CFI 5.0 and AOD and going into a car that is lighter than the original applications for this engine.

    Just beginning some information gathering, mainly for the engine/trans management. Looks like I can do an aftermarket ECU and even TCU, or using the stock stuff is possible with programming changes (I think SCT Tuning was a mentioned source, mainly for disabling a few stock systems). I think the route depends on what I wind up with, I suppose. Getting a complete donor vehicle will probably be more difficult, but I guess we'll see.

    Anyway, going to keep digging into the management options and such while I work on other areas of the car. Rear suspension and AC are currently next on the list.

    3.7 engine is no slouch. I am not super familiar with that engine, but it definitely put up some impressive numbers.
    I wish you luck, controlling the engine will be most important to get those impressive numbers.
    Great choice.

    This is why I'd like to do factory, if I can. It's just the logistics of getting a whole, most likely wrecked, car here that are the issue.

    But an LTS is supposed to have a V8. That's what makes it what it is. A 3.7 in a regular Marquis would be cool, but in an LTS....

    Keep the V8, sell it with the car?

    The LTD LX/LTS were meant to be solid/balanced performers with 4 doors. In the '80's there wasn't much choice for a powerplant to power such a vehicle.

    I'm not stuck on it "needing" a V8. I don't want to dump $$ into building a SB 5.0, nor do I want the expense of a Coyote swap. I have no love for the 4.6 motors, either.

    I did find a swap of a 3.7 into a '99 Mustang, which basically gives me a good proof-of-concept for a Fox swap using factory controls.

    This car is not going to be a garage queen, it's going to be a driver. Also, not just a driver for me.

    The car is living a better life with us than it has been for the past decade (or more) languishing and rotting.

    I say go for the 3.7! Itís not like these cars are sought after, even the rare ones such as an LTS. 300hp and 30mpg would be perfect for a car to actually drive an enjoy.

    While on the topic of more modern power plants into older cars, Iíve been kicking around the idea of swapping a 2.0 Ecoboost into either a 94 mustang (3.8/AODE) or if I end up with it in my possession, a 1970 Mercury Cougar. The little 2.0 with bolt ons has a near identical power curve as a bolt on SBF and can get 30+ mpgs.

    So go for it and let us know how it turns out!!

    Still messing with the "stiff" throttle just off idle. I have traced it down to it being the throttle blades are being "held" by engine vacuum, and it takes an extra bit to over come that. (The pedal is perfectly smooth when the engine isn't running)

    I've been trying to figure out an adjustment on the CFI that would allow me to crack the throttle a bit at idle, but I haven't been successful with that.


    All of the parts for the AC are here, so once I get the fuel system back in the F150 (going from a dual to single tank) I'll probably mess with that.

    Need to get the old bushings out of the RLCAs and get the boxing plates welded to upper and lowers and get the poly bushings installed too.

    Wow that's so wierd, you are just like "Meh, its a factory 5.0 Marquis, LX-type LTS, but I'm paying no mind to that, and installing a V6." Huh?

    We were all celebrating that "1 of 145" stat or thereof, and you are like pretending its my ex-girlfriend's car from 1990; a 1983 LTD II 3.8, or buddies 1984 Marquis, also 3.8.

    I think I'm missing something and will return to the the '79-'93 Realm of Capris and Mustangs! lol
