Devil, yours looks way different than mine. Your car is a 1996? I thought that dash was 1994 - 1995. Hmmm....
I'm using a Dakota Digital converter for the speed since the GM output signal is different than the Ford. The tach can be programmed through the PCM to be what you need but Dakota Digital sells a converter box for that if you can't reprogram the PCM.

I am really a Ford guy, but Ford screwed us bad with the ohc engines. The 4.6 in my car is larger externally than a 460 big block. Do the math on that one.
I still don't like the old school chevy small blocks, but the gen 3+ engines are a gem. It's the engine ford should have built and put in my car. I will just have to do it for them...![Nod](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_nod.gif)

Interesting. I didn't realize they still had drums on 1996 cars either, I thought that stopped in 95. I have disks all around but they were too small when it was a V6.
I agree, the mod motors are too expensive to update for my pleasure compared to my goals and budget (see first post in this topic). Acquiring a mod motor with the power I have isn't going to happen in factory form without forced induction (have you ever tried to price one
) which won't fit under my hood (see goals). Besides I'm only a factory cam and intake away from a power change I can feel. Add the right heads and we open things up again... Since my car is so easy to work on compared to a mod motor in theory I could start the H,C,I swap on Saturday morning, make a few computer updates, do my testing Sunday and drive it to work Monday if I felt like moving that quick.
Since I had to do the same amount of work to get a mod motor in the car (engine swap, transmission swap, harness, new exhaust, different drive shaft, etc.) I figured I may as well go with something that actually met my HP goal out of the box instead of modding something that didn't. Since I was committed to swapping engines I could do anything I wanted. Being a Chevy guy helped make the decision easier to lose the Ford V6, but didn't really change much beyond that.

Yes Sir. My car is a 1996 LX with the 4.6, 16" wheels w/drum rear (??), and factory 3.27 traction lock. I'm not sure if it's different because of the v8 or what. I'm not really a thunderbird expert or anything, I just like this car because there's more room in it than a mustang, and it doesn't attract attention (race at every light, thieves, etc.) I am really a Ford guy, but Ford screwed us bad with the ohc engines. The 4.6 in my car is larger externally than a 460 big block. Do the math on that one.

little tidbit of info. the 96-97 Sport rims are basically carryovers of the 1993-1995 SC wheels except they lack the small indent for prying off the center cap since the sport rims have a moulded plastic piece that leaves the lugnuts exposed while the SC's had a full lugnut cover with a bird emblem on them.

I found a driver who failed the bit in science class where the teacher talked about multiple objects occupying the same physical space at the same time.
After our altercation I didn't think my car was too bad...

Further inspection revealed the real damage.

At the proper angle you can see my engine work from outside the car - cool on a Corvette or other exotic but takes away from my sleeper / grocery getter low profile image. Besides I would have opted for something a bit more engineered if the choice were given.![Sad](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_sad.gif)
This obviously throws a wrench in my program of working on another project but most important - do I stop where I am and pull all my gear and put it in a different project or do I play body man and fix the daily grocery getting sleeper?
The crazy part is for all the apparent damage, it is only cosmetic. There was only one wire damaged in the whole melee (ground for my electric fan) and none of my fab work was touched. The car still runs and drives great but is a bit scary to navigate near crowded sidewalks.

Over the last two weeks I have driven the car to work and used it for all my daylight running for the first time since the wreck. I amazed myself as I had completely forgotten how fun this car is to drive! I had a few odd stares since I'm running without the fender and light but otherwise it drives completely fine.

I've already scored a hood, fender, wheel well and a bracket that holds the lights in.
![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
I removed the power antenna that was never used and didn't work, then filled the hole in my new fender with metal from the original. A few more tack welds, a touch of love with the body hammer and grinder followed a thin glazing of putty and a scuff or two of sand paper will make it primer ready.

Not much to update at the moment. With other projects around the house and work (thankfully) taking the lion's share of my time means not much has changed on the car besides the mileage. The most I have done is take the peeled fender off and drive the car to work and run errands. I get much more "respect" in traffic with no light and fender but I hate the trailer park "I was at the NASCAR race ON the track" look. I've been trying to find a set of used lights (pass side head and turn) to keep my salvage yard / sleeper theme going but it isn't happening so I'll have to purchase new. I'm kind of picky and didn't really want to do that which is causing a problem because I don't want one new light and one old. Buying new means committing to purchasing both sides to make it look right because the originals were fogged.

WOW, I must say this is an awsome thread, I made a username on here just to post some comments about your thunderbird project..i hope its not too late to revive the thread!
For one I'm a huge fan of the LS motors, and also love the MN12's, (used to have a 97 tbird 4.6)..I have been looking all over the internet for so long for someone to swap an LS engine into a thunderbird/cougar/mark viii and i finally found it!
I've read most of the 6 pages of this thread, and i see the little mishap you had recently (or at least within the last 6 months or so)..thats a shame, I really hope you havent given up on this project because of it..hope it's back together again..but anyways, i thought i'd share some pictures of my old bird and show some wheel options if you are still looking to change the hubs and wheels..
![](http://i713.photobucket.com/albums/ww140/vans1107/P1010016.jpg)
had both the cougar 7 spokes, and the stock 16" sport SC style rims
![](http://i713.photobucket.com/albums/ww140/vans1107/tbird.jpg)
also here is a car from my neighborhood that i have seen on and off for the last 3 or 4 years..(yes I actually found where the guy lives and stalked his car haha) I even saw it at the drag strip once randomly..wish i could remember what it ran..low 14s high 13s maybe? it had some work done to the trans at the least (judging by the hard tire chirping shifts everytime he passes by my house) and some kind of dual exhaust set up..but anyways he did the mustang hub swap and put on some older SN95 cobra wheels from the mid 90s, i want to say 96/97 cobras had these rims?? im pretty sure they're 17"s and i love the way they look on the thunderbird..in my opinion
![](http://i713.photobucket.com/albums/ww140/vans1107/IMAG0522-1.jpg)
and one last thing..considering you are driving this car in the winter I would HIGHLY recommend looking into some rust prevention if you plan on continuing to drive it in winter conditions with snow and salty **** roads because these cars like to rust out from underneath you as I'm sure you have noticed going to the junkyard as much as you do..this is partly the reason why I sold mine..I'd hate to put all the time and effort into an engine sawp and see the car start to rust away...BUT in any case, i hope the project is going well, and i hope to see some updates and pics of the car soon! best of luck!

Thanks for the kind words BFK86. Stalking the neighbours car, so I guess you're a fan huh? ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
The car is still alive so it's not too late to revive the thread. I thought for a short time about pulling all my gear and using it for another project but the voices in my head and friends here told me to carry on. Damaged body panels have since been replaced and put in primer. Now we are even more sleeper than before - 'cause we all know cars with primer are slow POS's, right.
I do a pretty good job at keeping the salt and crap off my cars in the winter and so did the previous owners. This makes the car 95% + rust free which coupled with no other major problems helped my decision to keep it.
Later this summer I will do a complete makeover by cutting out the usual rust spots and removing the bloody foam Ford put in the quarters to help promote rust.
Home fabricated sub frame connectors, shaving emblems, filling holes and new paint are top priorities followed by a laundry list of small refinements.
I have the Cougar wheels because the car currently has the "big" (yeah right) Mark VIII brakes. Ironically, they still don't stop the car in what I consider a reasonable distance at street speeds, especially compared to my other cars. These cars are severely lacking in the brake department - which may get upgraded again.
I still need to make a trip to the track and run. I know I'm severely traction limited and probably under-geared for that contest but I'm curious.

Brian, I have a way to get rid of the wheel hop on these. I have not tested it yet, but I have the parts. You need to add a trailing arm on the upper rear contorl arm. The reason they hop so bad is because the upper arm walks all over the place. There are other places to add the strength like derlin bushings on the LCAs, but you need a set of 'luminums to do that. Just so happens, there are 5 Marks at Uwrench it as of friday.
Oh...and I am sad that you are not a body man. I need help fixing a fender.
