[70Mach1]

Hello, I have a 1970 Mustang Mach 1 with a 351 Cleveland 2V, and a 3 speed auto FMX, and I have been wanting to do the swap to a manual, but im not sure how to go about it. Which bellhousing do I use, and which transmission? The engine is basically stock, its been bored 30 over, and I have a set of flows on it, So im pretty sure it cant be making over 300 horse... I really wanted to do a 5 speed, or a 6 speed. Also, where would I find the clutch pedal, the linkage, ect... Or I was also considering a 5 speed automatic if the manual conversion was to expensive... Any feedback would be appreciated! Thank You so much for your time! Anthony

Thank you, Im in the US, but what TKO would you suggest? the Tremec 3550 or perhaps the tremmec tko 500? and also which exact bellhousing to use?and how would I go about finding the clutch pedals and linkage? Thank you so much! I greatly appreciate your knowlege on this! -Anthony

It looks like I would have to go with either the TKO 500 or the 600, and I was looking around eBay, and I stumbled across a cheaper one.

As I was looking around online, and I found a 70 mustang, that had to make his tunnel larger to fit the transmission, it says "You’ll need to “lift” your tunnel to get the transmission to fit." but then on the following page it say that (Just to clarify, tunnel mods are not required in this era of Mustangs for a TKO 5sp). So does this mean I would have to do the gruesom surgery, or not?


I just ran across this. You can rebuild a T5 transmission with a G-Force gearset upgrade. Which will make the transmission capable of handling 600 horsepower and 500 lb-ft of torque...

If I went that route, then I would be able to use a 3 or 4 speed bellhousing with an adapter plate, which the T5 would bolt to... Also I would be able to go the the junkyard and get a used T5 for $200-500, and then just upgrade the gearset to the more then plenty 500 lb-ft of torque...

I also discovered that the manual linkage is hard to find, so they sell clutch cables to replace them, that are year specific to your car.

Tell me what you think about all of this...

Thank you soo much for all of your insight.

Well, once again you are right... the G-Force kit runs about $1100, so I might as well go with a TKO for a few $100 more... Heres the G-force website...

I was thinking, since the g-force website seems to think that it can handle so much power, as much as a TKO 500... so i wouldnt have to worry about the casing, right? The only reason im leaning toward the T5 w/ upgrade kit, is because you dont have to cut up the trans tunnel, which I really dont want to do, since this car is my daily driver and when I do this swap, im going to want to be in and out ASAP... even though the whole thing will still take quite awhile...

The car will most likely stay pretty stock, I may put in headers in, and after the car is a manual, and I wont have to mess with a torque converter and which stall to pick, ill most likely put in a nice sized cam... but thats about it.

Beside the better gas mileage ill get with the 5 speed, im looking forward to burnouts, and 2nd gear scratches, but thats all the radical im going to get with her... so do you think the case should hold up?

And I cant seem to find the pedals, I dont really care about originality, just some thing that works! Since youve done this before, how long would you say this whole thing would take me after I have everything I need?

What exactly does that clutch cable conversion take place of? Sorry to ask so many questions... Never done this big of a job before... and dont really have trans knowlege, rebuilt by brothers once... and my dad has done a swap before but his car was already a manual... Its the whole clutch pedal, and mounting that up, and connecting it, is whats getting me... theres soo many parts down there...

Thank you SO INCREDIBLY MUCH for your help!

Well thank you for your help, im sure ill be posting again for some more help from you, but now its just a matter of time before the money is saved, and the process of buying it begins... I just hope ill be able to find the clutch pedal assembly, because that seems to be a problem with the 69 and 70 mustang, since they are alike, but they were only produced for 2 years... so ill check out the Mustangs and Fast Fords magazines and see what they have... and if they dont, then I guess ill be using the creative side of my brain to rig something up!

Tanks again!

On second thought, what about throwing in a 5 speed automatic? If you perhaps know anything and could share your insight, that would be great! I just like having my options open, since what im hearing is that automatics are faster then manuals...

Read it for your self! --I didnt believe it!

What newer autos would even adapt up to the 351C?

OR if I was simply to add a lock up torque converter to my existing FMX 3 speed transmission?


THANKS AGAIN!
