In a junkyard somewhere
I have a Rockwell T-221 transfer case from a early 70's chevy truck that is married to a 465 4 speed.

What is going to be the con's of using this case.My main reason's for using it are.
1.I have it.
2.I have a spare.
3.It will not hang down as far as a 205,for a flatter bellypan.

I also have a 465/205 figure 8 combo,but there is no real way(that I know of)to index it up for a flat belly pan.This isnt going in my M-1009,but I am going to build a lo(er)-buck cab truck/hybrid/truggy this winter and want to run a 4 speed this time.
 
I don't see any real disadvantage, seeing that you have an extra for parts. What is the low range in it? What spline are the outputs(getting proper sized yokes might be a bear.
 
subcribed...there is a divorced t221 right up the street from my house for sale...i think the gear ratio is worst than a 205 though...something like 1.75-1...

That is what I was thinking too, The 4 speed could be enough gear though depending on terrain.

I have seen a 205 clocking plate. check ebay. I don't know how far it clocks it but searching doesn't cost anything.:dunno: I just clocked my 241 and its still not flat. I have a 2" body lift and I would have to cut the floor out to make the frame the lowest point.
 
Sitting here thinking about it I came up with this.


I have a 32 spline 465 with adapter for a 208.
I also have a Dodge DM 205 bare case.

Why could I not bore the case to accept a 32 spline married 205 input and then drill the face to accept the 208 adapter and clock it at the same time.The only problem I see is that I would have to make some kind of a bracket for my shifter since the adapter won't have the boss for the shifter to bolt to.

Anything I overlooked??
 
I can't see anything wrong with that. The shifter could be tricky, but it can be done. There was a guy on Pirate that built an air shifter for his 205.
 
Rockwells are turds...haha. I had a bad experience with mine, but I am definitely not alone. They are famous for lunching the input shaft bearing due to the case design (tall and narrow) so if you run low on oil at all, say bye to that bearing. When mine went, the balls from the bearing jammed themselves in the gears...was not a fun time at 55 mph.

On top of that, when I pulled it out, the output of the Sm465 and the sleeve were almost done, one good clutch dump and I would have stripped one of the two and my truck would have just sat there, valves floating, in 2nd gear. Of course, this is a problem shared with the fig 8 465/205 combos.

The Rockwell's low range ratio is 1.94:1, so it's basically identical to the 205's (1.96:1).

I also don't know how you'd go about twin sticking one...I would just chalk it up to a waste of time and get a 205.

Additionally, if for whatever reason you ever wanted to run a PTO, good luck finding one for the Rockwell.

In case I haven't made it abundantly clear, avoid the Rockwell. If you *must* use it, go through the case and re-seal it, and check the oil level FREQUENTLY.
 
Yes, but it would make a slick set-up. It is hard to do a lowbuck build up. That is what my k5 started out as. I would hate to sit down & figure what I have spent on it.
