Which would you put behind a big block and auto?

ORD Gen 2 doubler, or a 4.3 Atlas II

Depends on the wheelbase.

Definately depends on the wheelbase.

But the strength of the 203 range box and 205 is really hard to beat. But the thing aint light though. I would prefer the Dub behind a bigblock for sure. But that's just me.

I'm getting ready to put the ORD Dub into my Blaze shortly. Got it all ready to roll under, just need to find the time :)

I went with the doubler and a TH400 behind my 502.

Double reduction is for wuss motors and farm tractors...
If you have a big torquey motor you won't need all that gear. Spend your money on some axles that can handle the torque and some spares for those axles.
I hate to sound like a old prude, but, you guys are hanging so much crap on these machines you are asking for trouble. There are enough things that can go wrong without adding another device to the mix...

Take that $1-2,000 and buy 150 shares of lucent stock, or put it down on some property in the middle of nowhere, or buy fuel for that thirsty big block...


JMHO

There were some good comments here:

I agree with dirtrod expecially with a automatic. I plan to gear down some more (th350, 2.28 T-case, 4.10's and 37's) but thats because I have a little motor. If I had to chose between the two it would be the doubler because my vehicle see's more then just rocks and 4.3:1 or 3.8:1 would be to low and 1:1 to high.

I plan on having a big torquey motor, but it's not all about power from the motor. What I see as a reason for going lower is the ability to get the power to the ground in a more controlled fashion. If I have a motor that makes peak torque at arund 4500 RPM, then I would rather be in a 4:1 than 2:1. I can be more controlled with more gear.

That's just one reason that I am planning on a doubler. There will be times when I need to speed of 2:1 vs the contol of 4:1 The doubler gives me both.

Being a hammer down wheeler has it's place, but I'm not exactly one of those kinds. I guess we'll see in time if I made the right decesion.

Definitely with the ORD doubler if you've got the room. Wagoner Machine makes 3.6 gears for the 203. With an automatic you've got all the more reason for a doubler. It's certainly bulletproof, a lot more than an aluminum/chain TC. I've got a 203/205 setup in my F350 and am working on putting a NP200's guts into a 205 and then attaching a 3.6:1 203 to it for a divorced 200/203/205 for my diesel M37.
The control of 110:1 is great in the F350 even with 444 cubic inches and 500 ft-lb.

Well, the wheelbase will be whatevers required for the drivetrain.

I don't know if it will be all custom or something stock lengthened or shortened, but my basic idea is to start with drivetrain and build around it. What it looks like I don't much care.

I'll be making a post soon about what my plan / rationale is, and of course I fully expect you all to jump on and blow holes in it...specially you Dirtrod...i always count on you for a brutaly honest second look.

Wolf - what axles do you use? Any regrets? Do anything different next time?

With the ORD doubler - I assume the twin sticks are to choose between 2:1 and 4:1. Can you also use / modify it to shift either axle independantly like a "traditional" twin stick?

Try it...You'll like it !


Seriously ...if you have low end grunt, you are making good power at 5-600 rpms.
You can (and should) do whatever you want with your toy.

If I had money, more than likely I would be hammer down...:D

I tend to break less stuff if I'm technical.

I see you point about having good low end power and depending largely on the weight of the vehicle, a big block 3 speed auto and 2:1 is prb. more than enough, in a Jeep. Put that same combo in my overweight Blazer and I feel like I'm bonzaiing through stuff. It's a big guessing game alot of times. :D

well dirtrod certainly has his opinion and hey i wheeled a truck with 44s for about 4 years without a doubler but i personally like having a doubler just cause it gives you more options and if you liver around here you would also know i like have the horsepower approach at times and gives a shit about breaking but sometimes in some events you might not want to look dumb grenading something on first obstacle(not to mention have the time to fix for next event,etc) and that is why i like the doubler cause you can control wheel speed when desired. But hey that is just my opinion.

Front: Dana 60, 5.86, Detroit, 35 spline inners, 35 spline outers, full time lockout hubs

Rear: Dana 70, 5.86 gears, Detroit

I'll give you an answer on the 203 when ORD finally ships it too me. It's been on order since January 5th. They truck is apart waiting for it.

I'll have: 2.48 (TH400) x 1.96 (205) x 1.96 (203) x 5.86 = 56:1 x 2 from the torque converter, so 112:1.

It's behind a 502ci engine putting out over 500 lb/ft from 1750 to 5500 rpm. Max torque is 560 lb/ft.

Sorry to burst anyone's bubble, but even 560 lb/ft is not enough in some situations, no matter how hard you hammer it. Plus, the control of gearing, both for crawling and downhill is necessary, even with a big engine.

Tim.

Ha Ha ...No one ever busted my bubble with words...Or with another machine for that matter...
Anyway... I get my sorry ass out west one of these days and you guys can show me how to really wheel...Until then, I'll keep doing what I do, and I'll enjoy it , even with my lame gearing. :)

Dayum,

Wolf...can I have your rig please :D :D

Or yours BigBlaze...:D :D

I'm tired of nursing the beer can on wheels, and I want it all....big power, low gearing, big tires....

I want to be able to crawl technically...or hammer down....

Since you guys know - where can i learn more about the early manuals? Like what the heck is a "full reverse manual valve body" and why do I want it (or do I?)

Did either of you guys have to do any custom work to your rear axles (the 70 and 14)?

Up until now, I had a lot of respect for you DR....But Why the Fawk would you buy Lucent stock?:flipoff2: :flipoff2: :flipoff2: ...jk...but really, Lucent sux azz.

I didn't say I'm buying it..It was just a suggestion


But,

They Are sitting on 3 billion cash... They will be ok

I like your rig, Good job at the challenge...

With a Doubler you will have a minimum of 2 sticks, one for the 203, and one for the 205. You can then Twin-stick the 205, (as has traditionally been done) which essentially triple-stick's the whole shebang. But, i think the linkage situation could get hairy if you wanted them to all come out of the same hole on your floor....

i had a twin stick when i just had the 205 but of coarse now i have a triple stick but like you said i had to open the floor hole up a little and extend all of my linkage and make a pivot bracket but thats not the real pain but with the gen2 doubler the rear driveline shifter has to make a bend around the 203 and it is tight area to work in! but worth it
