Since the torque on the shaft is not transmitted through the carrier bearing
I can't see where it would be much of a problem.  The bigger point of
failure I think would be the extra universal joints.  The other thing to
consider is that the  reason for the 2 piece shaft is to allow the truck to
go over taller objects without banging the drive shaft (approach angle?).
If you go to a 1 piece shaft it will hang down lower under the truck.  If
you go with high quality joints I think the 2 piece will be just as
reliable.  The other thing you could do is go with less sticky tires to
allow slip and protect the drive line.  If you're in competition this may
not be an option.

Have you called a driveline shop?  I would talk to some 4x4 guys too.
So just thinking aloud, you're welcome to comment:

It would seem to me that the shorter individual links of a 2-piece
driveshaft would have less leverage on things and therefore be less
likely to twist.  I am guessing though that the carrier bearing does
indeed impose some torsional restraint on the 2-piece shaft so I would
approach it cautiously as well.  It's been a while since I had a truck
equipped with the carrier bearing setup and I don't remember where the
shaft slides, before the bearing, or through the bearing.

On the single shaft....  I would look at how they do it on the big
trucks to see.  For instance, the new V10 Fords.  Do they have a
carrier bearing set up?

Somebody else mentioned approach angle and that's a good point.  I
would like to know if there are any current trucks that don't use a
carrier setup, and then investigate that setup further to see if it
fits into your HP/driving package.

I also agree that giving up some traction until you figure out the
proper way to go would be a good idea.  It can be as simple as running
a cheaper tire with a lower traction rating.  It would sure soften
things up until you figured it all out.  That Cobra Jet puts out some
serious torque and if you hook it all up with some meats and a big ol'
long driveshaft that's a little bit out of alignment....  eeek.

So no real answers for you.  Just putting two brains together....

Subject: AOD TV cable

Anybody swap an AOD in for a C4?  My C4 just lost second gear and I'm
thinking it might be a good idea to swap in the AOD I have in the
garage.  I am very afraid of the TV cable adjustment though.  I haven't
really seen an adjustment process and everybody says "MAKE SURE IT'S
RIGHT OR ELSE...." so I don't want to mess it up.

Can I just get a stocker type cable and fangle it or do I have to go
aftermarket?

Anybody know if the C4 yoke will work?

Any info that anyone could provide would be helpful.  I am familiar
with Windsor-Fox and  Baumann sites.

Subject: FE heads

I would like to do a little "port and polish" work on my 428 w/CJ heads.
I plan on matching the ports and doing a little smoothing,nothing
radical.
Any areas that need special attention?Any thin areas I need to watch?
Any tips in general?

you will experience the most gains by doing bowl work, this consists of
removing material under the valve itself when looking at the chamber. and
remove all the excess material below the valve seat itself

Wow, fun :)

My 4x4 doesn't have a carrier bearing, its a long bed as well ... I'm trying
to remember when the carrier bearing came, and I keep thinking its the heavier
3/4 ton and long bed/super cab pickups ...

Have you broken the one you have yet ?

I would think the two piece would be a bit stronger as the shorter shafts would
be less prone to flexing and bending under high torque loads, but you will lose
some power through the extra joint ...

Another option too is an aluminum shaft, that's what the Lightning's went to
because the stock steel one wouldn't hold the torque on shifts ... but that
is a shorter shaft.

Heh, spend the big bucks, get a custom carbon fiber one :)



> I would think

>fail.

What gears are you runnin ?  And its not the hp that kills the shafts, its the
torque, the low end launch and 1-2 shift is more likely to damage the driveshaft
than spinning it faster with higher revs will ...

Just my $.02
