You say you have a C-4, so you must have a 240/300, or a 302 and it is 2wd. The C-4 can be exchanged for a C-6, but IIRC, the C-6 is about 11" longer, or thereabouts. You will have to shorten the driveshaft the required amount, or find a C-6 shaft, and the shift linkage might have to be exchanged for an FE C-6 set. The SBF pattern C-6 can be found in 80's trucks and Econo's. Why do you want a C-6? If going to that trouble, why not go OD with an AOD, or with an electronic controller-controlled AODE/4R70W. If you still want the strength of the C-6, step up to an E4OD/4R100.

Rich is not wrong, but.....
Tell us what engine you have. C4 is typically a small block tranny and a C6, well it varies but is usually for a big block or FE engine.
If you have a small block, O/D tranny will be the way to go.

They do offer a C6 with a small block bellhousing. It will physically bolt up, not sure what all you might have to adjust to make everything hook up?

Swap
I once replaced an AOD with a C6 on a 86 Crown Victoria. I also had to replace the fly wheel because there is supposed to be a different off set.
The Ford parts guys on this site should be able help with this.
