NWF Black Box

Im betting its too new for anyone to have real world with it yet. The thing looks sick though. Also knowing nwf and their commitment to quailty/ customer satisfaction i would do it in a heart beat. id prolly do this over a doubler.
 
Oh it's new? I didn't realize that.

Yeah I'm bogged down with a bunch of 203 and 205 T Cases, and Trannies but of course they don't match up ideally. So I'm wondering if maybe the underdrive might be the way to go instead of buying, machining and rebuilding what I have/need.

in a way yes you can use it for that. it will bolt directly to your tranny and tcase. so long as its chevy stuff you dont need to do anything special.

Yeah I know that's not the ideal way to use it but it might make sense for me in the long run. For kicks I'll run it by you guys and see if you are in agreement.

Ideally I would go 400/203/205 for a bombproof low cost drivetrain.

I already have the 350 version 203 and 205 cases, and I have a rebuilt 2wd T400.

IF I can use the 2wd tranny without sinking tons into it (yet to be determined) I would definitely source out a 203 and a 205 or get mine machined as neccessary. If I can't use the tranny then the drive train wouldn't be 'bombproof' and not only would there be the increased cost of sourcing a TH400, I'm not sure I would feel the money well spent. And then the D44 would be a real wink link.

On the other hand my Blazer is pretty light judging by what I've read here. With a small block, D44, T350, no top/doors and a p/u gate it is keeping the weight down. If I stick with this combo (350/350/205) and use the 'Black Box' I can continue with the saving weight theme and perhaps the drive train will in effect be relatively as strong.

Any thoughts? Did I present that clearly enough? Does anyone give a hoot? :D
 
Logic seems fine to me, I'm long been of the thot that if the vehicle is light then you may not need the extra heavy parts. Marv's machine seems to be proving that.
What is the difference in weight btwn the TH400 and the TH350? Seems like thats the decider. Doesn't the TH350 have a lower first gear, or do I have that backwards?
 
same as a Klune-V with less ratio choices. I like that they have more bearing contact unlike the klune. why doesn't someone make a kit to use the reduction part of a 241. same thing as the black box.

350 has slightly lower first gear, and takes 9hp less to spin.

got a link? maybe I'm not looking in the right place, but I can't find it.:mad:
 
thanks wayne. I don't know what to think by that thread though. seems he is pretty busy. I called, no answer. If I can get some pics then thats the route I'm going.

There is also the weight difference between the doubler and the Black Box which I believe they said is half or less than half the weight. And in a round about way, the weight savings of running a D44 instead of a D60.
 
Buyer beware! Duffy is the reason I didn't make it to divide ride this year. He kept saying he had the parts and was selling them, so I got my rig ready to accept his setup. But when I tried to send him money he suddenly didn't have them; too late to go back and still make it to divide ride. :mad:

wtf? :mad: :mad:

I don't doubt he has 231 to 205 kits but 241 to 205 are a diff story

That was the weight difference I was driving at, just hadn't gotten there yet. :D
 
I wonder.... will the reproduced 465/203 adapter get revised for BlackBox usage? Maybe there should be a matching 32-spline shaft available? ;)

EDIT: Are the notches in the case (on the tcase side) there for 205 shift rail clearance? (assuming round pattern here).
