727 question

[72hemi]

I did a quick search on here and didn't quite get the answer I was looking for so here it goes. What is the correct 727 transmission for a small block in a Challenger? Does it take the short or long tailhousing? Does it matter? Are they interchangeable? What are the lengths of the different tailhousings? Are there any other things on the 727 I should be aware of other than the two mounting holes for the shifter linkage? What is the overall length difference between the 727 and the 904? I planning on swapping the the engine and trans out of my Challenger for a rebuilt 340 and 727 and have an opportunity to pick up a 727 for free (already have the 340) and I need to make sure it will work in my car before I go get it and start tinkering with it.

ok you are confused , the dual shift mounts is for the 833 manual trans , you need the long tail shaft , but I think on the 727 they are all long, the 727/ 904 the 727 is 4 " longer   

[72hemi]

Not the dual shift mounts on the 833. I read on a thread here that there are some 727 transmissions that do not have the provisions for the bracket that supports the shift rod from the slap stick shifter. Also do you know what the length difference is between the short and long tailshafts?

[Chryco Psycho]

you are right there is 2 bolt holes under the tailshaft housing for the shifter support

What are the lengths of the different tailhousings?  What is the overall length difference between the 727 and the 904?

Great that helps a lot, but what about hearing that there are 2 tailhousing lengths a short and a long for the small blocks that link only lists one?

[tactransman]

All cars take the longer length housing. The shorter one is for a bolt on yoke style for trucks only.

[72hemi]

Okay, so as long as the 727 takes a slip yoke and has the 2 lower mounting holes for the slap stick linkage I am okay?

[72hemi]

Also would you recommend a manual valve body for a street car?

Not really.If you get your TV linkage working right,it would be fine auto shifting.

I've had Turbo Action manual valve bodies in my last THREE street cars and I love them. No screwing with kickdown linkage and less internal wear because of the positive shifts. It's always in the right gear too. Whatever gear I put it in 

[72hemi]

THe reason I am thinking about a manual valve body is I hate adjusting the kickdown linkage and I have atendancy to change my carburation between single and different multi-carb setups and having linkage for that could be a pain, unless I get a lokar or some other cable kickdown linkage, which is a possibility.

[tactransman]

The thing about manual VB's is that they run MAX pressure all the time so they are a little hard on the direct drum (third gear and reverse) sealing rings as far as side wear. If you drive your car a lot,you might have to replace them on a regular schedule. (1-2 a year depending on how much you drive it.)

[72hemi]

That's what I needed to know. I am planning on making this car my daily driver again and don't need to be working on the transmission every year. I think I may get a cable kickdown linkage and go that route than. Thanks to everyone and the information. The transmission that I'm looking at needs a valve body who makes a quality unit with firm shifts?

Another question on transmissions the camshaft I am planning on running has a basic operating range of 1800-6200 should I get a stall or will a stock converter suffice?
