What he said ... The double overdrive is not "That" big of a deal.

For the money (I'm pretty sure a T-56 runs about grand or more over the TK-600, not to mention the adapter upgrades) and gear selections. Everything past 4th gear on both the 5 speed and 6 speed are actually overdrive gears.
I researched it and almost bit, but the TKO-600 was a better deal

Not only due to price, but it was significanly cheaper.
The 6 speed almost has too many gears for a BBF, if you gear it so 1st is usable, 6ths is ridiculously tall, if you gear it for 6th, 1st is too deep.
In addition it takes a lot more cuting of the floor pans, doesnt shift quite as easy, doesnt seem to be significantly stronger, and doesnt just "plug and play"
The TKO-600 uses a stock length 4 speed driveshaft, bolts to a stock 4 speed bell or blow shield, uses the stock speedo cable and gear, almost passes through the stock shifter hole, and is a nice spread from 1st to 5th.
Now the shock factor of a 6 speed may be slightly better, but I currently launch like a close ratio Toploader with a 4.56 gear in the rear, and when I hit 5th its a like a 2.36:1 gear.
Any more shifting would just give me an opportunity to miss another one
I have a TKO 600 behind a 521 in a 70 Mustang and absolutly love it but I am using a scatter shield and a hydrolic release set up, I am now in the process of putting a TKO behind a 428 and use a factory bell and Z bar set up and I am having trouble getting information. From what I have figured out so far is you can get a TKO with a FE short shaft kit for an additional 250 bucks if you are ordering a new trans, or you can get a standard shaft TKO and deeper bell for about 500 bucks or add an spacer plate to stock bell. I am told that you have to use the 390 release lever as opposed to the 428 lever but I have not been able to confirm this. I would think that someone sells a kit but I have not been able to find one. Has anyone out there ever converted a standard shaft TKO to a short shaft? how hard is it?
Did you have to enlarge the shifter hole forward without using a trans spacer? I used a spacer which put the shifter in the center and slightly right of the factory hole. I always felt the shifter in Mustangs is too far forward to start and used an offset shifter to move the shifter back and left so it is eaier to reach without having to use a "funky" looking shifter.

I can answer all your questions...

You do have two options: 1. Run the TKO with the short shaft kit. I sell them cheaper than $250. They are very easy to install. If you have access to a bearing press, you can install the whole lot in about 15 minutes. I sell the transmissions with the shaft already installed, or the transmission with a separate short shaft kit. It comes with the shaft, a new input shaft bearing retainer, a new bearing, a seal, and shims. 2. Your other option is to use a Quicktime bellhousing, which uses the stock TKO length input shaft, but it will put the transmission out about 3/4" away from the motor than with a stock/Lakewood bellhousing.
The input shaft on the TKO 600 is a 1-1/8x26 spline. You can use a small input shaft Toploader clutch fork as the throw out bearing for the TKO is pretty much the same size. I sell the clutch forks as well, and have them to work with a mechanical linkage setup or a hydraulic setup.
If you have any more questions, feel free to shoot me an email. I offer package deals from time to time, that come with everything including the pressure plate bolts and pilot bushing. I can sell the transmissions either way, with a Quicktime bell, or with a Lakewood bell and short shaft.
in my sons Galaxie. Only 20 miles on it so far but I sure enjoyed it. Have 2 TKO-600's going in the 66 F-250 and my 66 mustang, both FE's. I'am thinking the truck should be pretty straight forward (2-wheel drive), but the mustang with the FE should be a little more work. I was going to do the viper spec T-56 which will handle the same load, but my blue collar upbringing just would'nt let me write that big a check for a trans setup. If you use the Quick time bellhousing you can run the standard shaft TKO and drop about 20# over a McLeod or Lakewood piece for the same money. I got my stuff from Brent. Mike
I have done it on my 67 mustang hardtop. It is a T5 Z model from ford motorsport. my engine is a 390 I used the stock clutch and all linkage etc. and then used the stock big block bell housing for the s code mustangs and used the same adapter plate that you would use on the small block setup it works great and is an economical swap. people tried to rip me off on the bellhousings but I found a decent one for 100.00 the adapter plate is 150. at most mustang vendors and I had to shorten the drive shaft an inch as is usually done on the small block setup. the T5 holds up great and i have 3.89 rear end gears. I would never take it to a drag strip though as it would probably eat my tranny I have some pictures of the mock up if you like just email me and I'll send them
is there a kit or parts available for clutch pedal and related stuff to complete the swap from auto to stick in a '70? I see a lot of trans kits but not a lot on the rest of the swap -- hydraulic or manual? thanks
The problem I see is that the 5 speed doesn't have a very versatile overdrive ratio. A .64 is fine on the freeway but everywhere I drive has 40 miles of 50mph country roads before i get to a freeway and .64 is way too high to be able to use 5th. A .82 wouldn't be enough overdrive to be worth swapping. I'd just be leaving a 4 speed in it and using a taller tire.
I don't really need six gears, just one in between direct and a .64 OD.
You have two choices of od ratio and can get with a short shaft that will fit a stock FE bell housing. Mine has a .64 (i think) od and at 70 engine turns 2050rpm with a 3.90 gear and 28.5 tires. Got mine from Liberty, they did their magic to make it stand appx 900 lb ft and shift extremely good. Stock TKO 600 is about $21/2200 everywhere now.
I've been thinking of putting a TKO-600 in my 1972 F-100. Correct me if I am wrong, but I have been told that the pickup bellhousing is deeper than the car bellhousing. So if that is correct, I would not need a TKO with a short input shaft if I am using the pickup bellhousing. Is that correct?
My memory is a little rusty on the exact order of changes that I made to my truck over the years; but...if I'm not mistaken I put a small input Toploader in my F100 with the original bell-housing and ran it that way for several years. Then later I installed a Lakewood bell-housing using the same Toploader. I didn't realize there was a difference in depth at the time, but I believe there is. But I had no problems using either combination. FWIW, the TKO will fit in the F100 with good clearance to the trans. hump if the truck has the bolt in trans hump installed. My truck didn't have it, but I picked up the hump cover in a salvage yard, and cut out my floor pan to match. Without the removable hump cover the TKO is almost 2 inches too tall, as you can see in the photo. I just installed my TKO a few months ago. I bought the 2" offset shifter to use with it. Hopefully that will help someone.
