Pic will only tell you that it has the factory shiftier. You might be able to use the serial # on the case and call Tremec ask them for info on it.

if for some reason, it happens to be the 2.97 1st gear trans, Ill buy your setup when the time comes.

Alright boys just got home. Converter and trans brake was a huge success. Dropped my 1/8th mile time from a 7.2 to a 6.58 at 110 mph 60 foot dropped to a 1.54 from a 2.2. The car is nasty. I only have one vid from my cousins go pro that was racing me in his 351 turbo 94 cobra. I will get the other vids from my dad shortly. Enjoy

This pass went 6.53 at 110 mph.

Car is starting to move now! What suspension setup do you have?

I have coil overs up front with tubular a arms and kmember. Rear i have a fully built 8.8 with 9inch ends spool. Strange adjustible shocks and some no name springs. Adjustible control arms and spherical bushings. Antiroll bar

Nice pass OP, when you get the chance could you put together an updated parts list for this swap? After watching that run I need to ditch the T56.

How much boost are you running? What brake pedals did you use?

the 2013 Gt driveshaft you are using did you have to replace the rear side yoke where it attaches to the differential? It looks like it but I can't be positive

Very nice build. Would love to do this swap in my Cobra.

can we have a more up to date and dialed in parts list, the little things as well?

Not Paul but I can answer some questions.

Can use the 1 you have. Just have to remove the clutch pedal, only attaches by 1 nut.
Goggle the pedal Assembly to see what I mean.

Yes you have to remove the rear yoke on the MGTM part # drive shaft. And use the 1 you have. Assuming you have a SRA.

Edit: Grammar.

doing this swap now and this is what I came up with. GL

2011-2014, F-150, 2wd, 5.0l. 6r80.. Try Car-Part.com
Bellhousing to engine block Bolts. N606067*S439-Need 7#.
Drive shaft, M-4602-MGTM.
Drive shaft Bolts to 6r80, N800594*S100. Need 4.
Flywheel, BL3Z-6375-A.
Flywheel Bolts, AL3Z-6379-BA
Backing Plate, AC3Z-7007-A.
Torque Converter Nuts, -W714689-S437.

I went with the Shrader trans mount, spent 170$ more then the Stiflers trans mount. So that's up too you. I am happy, looks a little cleaner. and bolts to factory location.
Sharder Trans mount.
Isolator trans mount. BR3Z-7E373-A
Isolator Mount Bolts. W715936*S437... 3 total.
Isolator Mount Nuts. W520113*S440.. 2 total.

I went with stock 99-04 auto shiftier. *Shiftier cable is XR3Z7E395-AA.
Your going to need the power by the hour shift lever. Your going to need the stock F-150 6r80 cable bracket. (I will make my own swap thread in a month or so) Have to modify both the 99-04 shiftier and the F-150 cable bracket to work.

Went with the Power By the Hour Trans cooler fittings.
These parts are what I went with. You can detour.
Jegs -8an Push-loc hose. Good till 300psi. 555-102022. 15ft.
-8an to 1/2 npt. 10225- need 2.
B&M super cooler 70273. Might be too small though, so picked up another.
-8an push-loc fittings. 555-110052.
-8an 90* 555-110072.

Ok now the Trans controller. The Quick 6 takes 5-10 business days to make by hand. You will also need a Autometer tach adapter 9117# to run with the Quick 6.

Then you need to figure if the stock Intermediate shaft and the clutches will handle your power. I bought the Power By the Hour 1000hp kit. Which includes the above+ some rubber parts.
If you do have the 6r80 rebuilt you will need these.
6L2Z-7N134-BA.. Front pump to trans case. Need 13 total.
6L2Z-7A248-AA.. Front Pump Seal.
6L2Z-7052-CA.. Extension Housing Seal.

You can detour on certain parts. i.e shifter, cable, trans mount, trans cooler.
I also bought from jegs a strange pinion yoke part # 873-U1596K. but the stock set up is good enough.

If you have the stock IRS. I wouldn't buy the MGTM drive shaft. Install everthing else and measure for proper length.

I did stay with the stock torque convertor. A couple guys into the high 8's with the stock TC and blower. So it can handle it.

Thanks for all the info and part #s I plan on doing this .

No problem. I just want to add I did a little of the leg work. But I couldn't have done it alone. So thanks to paulstang347, Michael Plackis and holiks03cobra

Great info and parts list! Thank you! @ShootyMCstabby

doing this swap now what do i need to do for a irs?
