Long tailshaft 727?

A motorhome 727 will use the same length driveshaft as a 904? Adapter U-joints? If true that makes the motorhome 440/727 a guy is offering to sell me attractive for the next powerplant for the Demon I am getting. That way I can put in my SB/904 for now while I get used to the car and build a big block.

You need to start your own thread with your problem because it gets confusing to try to answer multiple questions in one thread. And a lot of guys get mad because your thread jacking when you post your question in their thread.

But to answer your question, No, they are not the same length. And the vast majority of motor homes don't use a slip yoke like a car. They generally use a 2 piece driveshaft with a slip yoke in the middle. I've heard you can use some sort of an adapter but I don't know what it is.
