Read the Road and Track article in the Shelby thread and you'll see that in the new Shelby, the Mustang GT's two-piece driveshaft and 8.8-in. 3-link rear axle are retained. Hmmm...

 

This guy just installed a Viper spec T56:

Wow, just read it, makes me wanna have one! 4.30s and he's at 1,800rpms @ 70mphs? That's just awesome! Imagine how hard you can play and how much gas still save!

 

You do realize that the new Shelby doesn't have a T56, right? It is a T6060. And they are about $12k.

DDPerformance has Viper T56 conversions for $4995, or you can use the Cobra T56 for aournd $3900.

 

Yes... everyone seems to think its still the T56 and its not...

It'll catch on eventually...
Say it now...T6060

 

There is no such thing as an easy swap out with our cars.Theres about four or more electric conections on our trannys and do you think the shelbys will all be the same.Just like the fuel pump deal.I dont think so.

 

Easy is in the eyes of the beholder. I'm 50 so I remember any type of swap involved services from a machine shop to fabricate custom parts.
To have available custom kits, like from D&D peformance which are basicly bolt- ins with a few electrical mods is a dream. Sign me up for a cobra-spec T56 kit today.

BTW, the Road and Track article states, refering to the TR6060, "This is a much improved T-56 with triple synchronizers."

 

Yeah don't forget to mention that the Shelby has a 5.4 not a 4.6

 

I was contemplating putting a Richmond 6 speed in my 05 like I did in my 66. I'm still trying to figure out the whole thing, but fabbing up bypasses or adapters for the electronics is making me wonder if it is worth it.

Anyone know if the TR6060 is a true 6 speed or a fake one like the T-56 (4 speed with 2 overdrives)?

 

its the same as the T56 just stronger thicker parts and more sycnchro's

 

You'll probably be able to pick them up from wrecked cars or from wholesalers for the current price of the T56 in the future. Sounds like the way to go if you can wait.

 

Even if the Cobra is a 5.4 and ours are 4.6, isn't that just a matter of getting a different flywell and that's it (as far as adapting it to a different engine)?

Also, would the 6 speed from the 03-04 Cobra work with ours? It's out of a 4.6 as well.. what are the thoughts about that? Would it be as much work as the write up that guy did?

 

The blocks for the 5.4L and 4.6L are the same...its the difference in the head that makes the engine larger...so there shouldnt be an issue bolting a T6060 on.

 

even better... that's nice to hear

 

Eh......negative ghostrider. Go back to engine school. Displacement is calculated by bore and stroke which has nothing to do with the heads of a motor.

 

The heads of the 5.4L are taller then what is on the 4.6L (thus increasing volume of displacement), thus making the 5.4L a longer stroke 4.6L...Just like a 302 vs a 351 head.

How do you get a longer stroke? taller heads!

 

I think its 4 speed w/ 2 overdrives

 

Sorry GT98, heads don't have anything to do with the stroke. The stroke is all within the block, how far the piston itself travels from TDC to BDC. That's done with changing the geometry of the crank/rod/piston wrist pin connection. You can get two displacements in the same block, with the same bore, just by changing out the crank/rods/piston to make sure they don't extend past the deck height of the block. The 350 chevy is a great example. Add in the crank from a 400, and you get a 383. Same bore as the 350, same heads, same intake, but now a larger displacement.

The heads can make a difference in combustion chamber volume, which will affect compression ratio, but you're not going to get a bigger engine (cubic inches) by swapping just the heads.

Make sense? Or did I muddy the waters some more.

 

Good thing you explained it so well. I would not have been as tactful...

Only thing I would add is that since the deck height on the 5.4 is taller than the 4.6, it is also wider.

 

But the point of the thread is to know whether the transmission can be just bolted on, and if the block is the same, the it could potentially be just a bolt-on, right?
