OK, I've decided that the "six" is the way to go. I would like to make it easier to drive so out with the "three on the tree". I'd like to put a 727, but I'm not sure that they actually even made a b body slant 727 combination (I know this doesn't meand that it's not possible). Whats the best set up? Where would I get the best possible doner? I know that linkage will need to be made for the kickdown. I'm thinking that the lokar setup for the others might be adaptable. The column and pedals are handled by a doner car. BTW it's a '71 9 passenger Satellite wagon. Any help would be great!
Thanks,
Sam

There is a 727 trans made for the SL6, ("G" engine) this special case transmission started in 1970 and was mostly used in the Tradesman Vans.

In fact, I talked to a friend who has a completly rebuilt one for sale:
Bob Arana (209) 333-8403 (Lodi, CA)

Do you already have the engine?

I think the 727 might be overkill behind a slant. Not only is it a much heavier transmission but it takes more horsepower to turn it. I think a 904 would stand up to whatever use you might intend, inless you use your wagon to haul fully loaded trailers or are going to build a 500 HP motor and do neutral drops all day.

My 1985 d-150 truck has a 727 behind the slant 6. I can't say if it has lots of negative weight and power problems, but I don't have anything to compare it to. Perhaps it's why my gas mileage is so bad.

I've found cost to be the big factor. My used 727 cost 3 times what a used 904 cost. But it's Ram tough.

The 727 has a longer tailshaft, so a driveshaft shortening is usually involved between a 904 and 727.

A 904 would be good enough, but a good 727 would last forever, and ever, and ever.

Well, the other thing that I have to consider is the availability of an overdrive unit for the AT. GV makes an OD unit for the 727, but not the 904. I do like the idea of saving weight (it's a little overweight right now as it is), but I am also going to be building the car for daily use. I specialize in motor electronics so you can be assured that we will be installing port fuel injection and the possibility of a turbo is there as well. I'm tired of building the same old gas guzzling big blocks. I know it's not a race car and never will be, but when fuel here is about to hit the $3 for 91 octane, I'll still be cruising when everyone else leaves there gas hog in the garage.

If you want an automatic with overdrive (don't we all?) why not just spend the oney now to upgrade to a A-500 or A-518 and use the adapter plates. These transmissions are factory overdrive units that came in 88-95 or so dodge trucks and vans,. THey have the small-block bolt pattern but will bolt right up to a slant six by using either the original factory adapters put in A-100 trucks and vans or the new remanufactured adapters currently being produced (who makes these? I forgot...) I plan to do this someday on my 72 road runner. A 225 with an A-500 (based on the 904, the A-518 is based on the 727) and an 8 3/4 rear end could run rear 4.10 gears on the street and still get okay mileage.

I had no idea that these where adaptable. Then I could run a lock up converter as well. Anyone know of the manufacturer of these adapters?
