    T56 swap

    Well it's official I am 100% sure I'm doing a t56 swap on my 92. So far I have an lt1 t56 I am buying so I am wondering what other parts are going to be necessary to make it happen. Here is my list so far.
    McLeod twin disc clutch sbf
    McLeod slave and master cylinder kit
    McLeod t56 bell housing part # 8750-00
    Longer custom 4" drive shaft 27 spline t56 1350 series yoke
    Trac loc with 28 spline different 410 gears

    I've never actually done a t56 swap, but I havd done a number of t5, t45, and tr-3650 swaps, and have looked into the t56 swap a few times. My method for those swaps has been to use the Mustang clutch fork with a 94/95 4-cyl S10 slave, which is externally mounted, and a custom bracket to hold the slave in position to push on the Mustang clutch fork. If you are using a bell housing meant for putting a t56 into a fox body mustang, I see no reason why the same setup wouldn't work.

    Plan to try this setup to eliminate having to pull the Trans when and if the slave fails. I plan to use mcleods setup as well as a McLeod fst twin disc clutch. The bell housing and input shaft is were the ? Comes into play on my end. I think it's the 26 spline ford and sbf t56 bell housing but that's were the fog is for me. To eliminate as much shimming as possible I want to use the best components.

    Thumbs up

    I think the use of an external mount slave is a great idea. It would make it alot easier to change (not having to pull that beast t56) and if it ever leaked, it wouldn't get oil all over the clutch. but thats my 2 cents

    slave cylinder?

    Well the more I research all of this the more confusing it seems to get but to far I have figured a few things out. The t56 I am buying is an lt1 firebird so the mid plate on it is configured for a shift fork. The bell housing I found is an frpp t56 to small block ford and has the entry slot for the shift fork but I don't know which fork I will have to use (early ford or lt1). If I go with the internal slave I can switch the mid plate cover to an ls1 which will accept an internal slave. I am going to call one of the techs at McLeod tomorrow and see if they have any idea but any input is greatly appreciated. I was reading the other threads on the t56 swap but they are using different bell housings than I plan to use so Its all a bit confusing to me.

    Use the mustang clutch fork and throw out bearing. Make a bracket to hold the S10 slave in position to push on the Mustang clutch fork, with a piece of threaded rod and and 2 nuts locked together as an adjustable pushrod. As for what input shaft and clutch to use, I would research the depth of the McLeod bell housing compared to one for a T56 in a 03/04 Cobra. If the bell housing depths are the same for those 2, then use the 03/04 Cobra input shaft because that will give you the right diameter for the pilot bearing, and allow you to use any Mustang clutch kit. If there is a big difference in the depth of the bell housings, I would use whatever input shaft has a similar depth bell housing, then for the clutch you will have to separately buy a clutch disc for that car and a pressure plate for a mustang, and then you will have to make an adapter or something for the pilot bearing.

    The bell housing is an frpp mod to sbf. The input shaft I have to use is the 03 04 cobra 26 spline. The bell housing has the mounting position for an external slave cylinder already but I was going to use the McLeod master and slave because of the stiff pedal problems John ran into. However if the S10 unit will work with the stock tbird master cylinder that would save me prob 500 dollars.

    Might be an option to take on the bracket but the wilwood 3/4 bore master cylinder I found is 70 bucks. These guys are way over priced

    Information on lt1 t56 swap

    Well after making a bunch of calls to t56 specialists and McLeod the list of parts that will work with a 26 spline t56 LT1 transmission are as follows
    LT1 t56
    frpp or quicktime t56 to small block ford Bell housing
    Mcleod fst twin disc 800 hp clutch
    Mcleod 1400-22 internal slave
    McLeod 8-1380-4 extended pilot bearing
    Wilwood 260-10372 3/4 bore master cylinder (may need bracket some fab required to clutch pedal assembly)

    Custom 4 " drive shaft
    373 410 or 456 gears.

    I plan to leave the rear dif 28 spline to save a little money now because at this stage in the game a solid axle may be in this cars future.

    hey Dave, just curious, what made you select the lt1 t56?

    I have a t56 from an 03-04 cobra that I bought for my lincoln ls (to mate to the 4.6 modular swap), the engine and trans is sitting next to the car right now since im out in Wyoming with work but I'll be tackling it when I get back home next year.

    I had contemplated snatching another one up for one of my supercoupes since most of the 03-04 cobra's I deal with get swapped to 4r70w's so I can usually come by them often enough

    btw, I don't have cell phone service out here so if you sent me anymore txt msgs I wouldn't get them. Just shoot me a PM or email if you need to chat at me.
