drivetrain question
Ive been doing tons of searches and cant find any info
on a 250 or 350 super duty, what is the limit to pieces in the drivetrain?
i.e.
axles
transfercase
6 speed transmission
differentials
driveshafts
I found the transfercase limit at 7800 etc.. foot pounds
but what is the limit for the rest?

You might get some good answers from Brian's Truck Stop, the builder of the famous BTS transmission.

Driving it on the street, all of it will hold except for the clutch. Pulling or racing it....well the 10.5" rear is stronger than a D60, may have trouble with the D50 front if equipt. The 283 t-case is pretty strong...but it is aluminum. You can't make enough power to kill the ZF-6, it put's the NV4500 to shame.

The stock tranny in a Powerstroke won't stand up to much more than around 350 hp at the rear wheels. It definately won't do for what you've got planned. Give Brian a call and tell him your plans. He should work with you. Go to www.brianstruckshop.com to get the phone number.
Edit: I missed the part about the 6-speed. My post is talking about the automatics in the Fords.

I also forgot to mention
the ford is going to be a 99+
is the 10.5 rear fairly strong on these trucks?
I know on the dodges they have a D80 and havent had any probs
with the ZF 6, is the only upgrade I need on it the clutch, or is it pretty bullet proof only when its rebuilt with aftermarket?
I cant find any information on a 283 transfercase, I was under the impression it was a 271?
maybe Im wrong
how bout the stock driveshafts?

the 10.5 sterling rear is definatly not your weak point no worries there. that tcase will take a pretty good beating as long as the chain isn't old and stretched (might be worth the money to go through it before your engine is in and running) For the drive shafts I would replace the ujoints with a good quality units, greasable is fine if not going to be used offroad, but if you plan on seeing a lot of mud and water with it go with the none greasable type. I also would take the driveshafts into a reputable driveline shop and have them balanced, properly balanced they will last much, much longer. the major weak point is going to be that D50 front, that thing isn't sufficent with a stock 7.3 let alone something with some power coming out of it. and if your running anything bigger than stock tires your going to be going through unit bearings regularly and at $270 each approx plus labor of putting them in thats not fun look for a kingpin D60 and swap it out.
I think others have covered the trans already so will leave that were it's at.
