Recently had my 351c rebuilt into a 408 stroker. Wondering what years and vehicles I could get an AOD to work with my 71 351c 4bbl. Also what would be a good rear end gear ratio. Stock is 3.31. Would like get off the line better but still be able to cruise at 60 mph without too many rpms.

 

I use a 4.11 with my 410c AOD combo. Also use the 4r70w gearset in the trans which has a 2.85 first gear....so it gets going in a hurry.

With that said.....NOTHING....again....NOTHING from a pick and pull is going to work in your application. You need a heavily upgraded/modified AOD to put behind a cleveland stroker.

 

Any AOD or AODE that bolts up to a small block will bolt up to the Cleveland block. I would see what the Fox body guys recommend as the best source for a core to build up. They have the experience with the AOD as its developed of the years. You can play with gear ratios on any number of online calculators.

 

Just read a Mustang Monthly article from 2006. 93' and earlier AOD from a 5.0 will work. Seems like 4.11 is the way to go.

 

yeah you definitely want a 4.11 in the rear..also iirc the stock FMX flexplate will work for a AOD

 

Just spend the money and do it right the first time and get a trans that will work in your application like Dodge said.....something built. Breaking **** gets real expensive, real fast.

 

I have an AOD behind my 408W. It was an Art Carr trans, and I have had it built. (Was only rated for 500hp. I'm over that.)

I think it originated it's life in a 92. I think. Nothing about that trans is original

I'm running 3.50s in my rear. Like the feel. Quick, but streetable on the expressway.

 

I'm getting the feeling that buying a used AOD and swapping it out isn't that great of an idea. I may have to wait, still recovering from the engine rebuild.

 

Major engine swaps to more powerful engines, typically require changing just about everything else in the car to not have issues. Transmission, rear end, suspension, chassis reinforcement etc.

Taking a car that was designed for 200hp, and throwing 400 or 500hp in it starts breaking things. All sorts of things.

 

I know I have my war wounds

And I even upgrade all the stuff from the start....just not upgraded enough...a 410c can be a monster....but worth it
