727 Short Tail Shaft
« on: November 12, 2008 - 10:45:43 PM »
I picked up a 727 about 6 months ago and it has a short tail on it.  Will this need to be changed out when I plop my 440 in my cuda? rear end will stay the same 8 3/4...

Yup,you'll have to change it. Are you gonna rebuild it it before you put it in? I know you can. ;)

HAHA....you read my mind T....the guy said it was recently rebuilt, but I want to redo it anyhow just to be sure I've got the good stuff in there.  So we'll have to team up again and do another thread on rebuilding a 727 this time.  :ylsuper:

Sorry,I don't have a pic of a short shaft 727 at this time,the difference is obvious when you see it though.

I mean what is the difference in performance or usage? Is the shorter one weaker? Is it only for certain uses?

There is no difference in transmission strength.

Ok. Then the only difference is length and you would need a longer drive shaft

You do not want to use a shorty in a car. There is no slip yoke so you would need a two piece driveshaft and a carrier bearing.

I didn't think the shorty was good, but wanted to consult the experts here.  How much does a tail run for?  Cheap?  Expensive?   :dunno:

They are still pretty common so they shouldn't be more than $30-$40 for both. When you change the output shaft though,you need to make sure that it fits the splines on the front planetary because there is two types of splines.
