NP 435/205 info...

Post by Clem »

Howdy to all. I am building a jeep. Before anyone jeers me off your board, I am using Ford parts for my project. I have blown up my last stock tranny. I am looking for any and all information on Ford NP-435's and NP 205's. Specifically, I am looking for the years that Ford run the 205 behind the 435. I have also been told that there are two lengths of inputs on the 435's. 6.5 and a 7.5 inch lengths are out there. Thank you for your help. If any of you are interested in getting rid of a 435 and 205 together... Lemme know! :D

Welcome to the site. Nothing like a sturdy drive train. I used to run heeps myself. I had a mixture of crap in them. Take a look at this site.

You might have a problem with the 205. I was going to place a 205 in my MB, but in order to to do that I would of had to fab the frame to get up in there. Just an FYI for you. You might have it :hmm: out allready.

This is going in a yj. Off hand, do you know how wide the 205 is? I love the novak site. They are "geared" only for some jeeps. When you get off into this "other" stuff, they kinda aren't as big of a help. I am setup with a 31 spline shaved nine in back (set up as an early bronco). I have done the dana 44 swap up front. (waggy and dog parts) I am running a mid-eighty's master cylinder form an e-350 van. It works quite well. Here is where you guys will think I am nuts. I am keeping the four cylinder. That is why the question about the input shaft lengths...
My ideal plan is to run the 435. Put a Klune in between it and the 205. I am already running 5.89's in the axles. That just is not enough gear for what I am playing on...

Welcome Clem Glad to have you aboard.... :hi:

I had a 51 Jeep Willey's,,,you couldn't stop that thing in the woods for nothing...It pulled a few Big Trucks out of the Mud.

All I ever did in the Woods was put it in Gear and Drop the Clutch.

Yeah, I have a few of those memories with mine. I have gotten rather serious about rock crawling. I don't figure that a tranny/t-case combo that is set up to handle big block power will have any issues with a four cylinder... BTW, I am in the DFW area. Other than Katemcy, are there any other rocks to play on out that way?

Here is my toy.

This is where this swap started...
(stinking ax-5 tranny)

The snap ring is missing off of 5th gear. This, believe it or not, is normal for this junk. I had another one and got it all together except the 5th/reverse detent spring/ball. Put it together and found that the cap for the detent was stripped. I put it together and it shot across the garage :cry: . So, I ripped it all out and this is why I am over here...

Isn't the Ford 205 going to have the front drive offset to the wrong side?

The Ford 205 is a driverside drop, so your diff will match up. I don't know what the deminsions are for the 205. I sold that thing awhile back.

Are you going to twin stick the 205?

Why not an Atlas II? Or even a Dana 300? The Klune is kick ass. I don't think you are crazy at all, the 4 bangor will be just fine for a power plant. You will have more torque and a faster rev. V8s are for the one that need to do 90 through mud holes or in hurry to run out of gas.

Everyone around here kept trying to get me to stuff a V8 in my 70 heep, but I really liked my Dauntless V6 w/ a 90lb flywheel. That thing could climb walls.

You still running stock axles?

Yep, I here ya on the money thing. They know you will pay the big bucks if you want it bad enough. I was just getting your opinion about the atlas and the Dana 300. I was going with the Dana 300 exept I was using a Cheby front D60. I didn't need to flip it.

The problem of course with the 205 is the lack of low gearing. With a 4 banger you're going to need to go really deep everywhere else. The NP435 will help ofcourse. I run that tranny in my Jeep. I think the long shaft 435s are 2wd only, not sure about that though. Mine was from a 2wd ford and I rebuilt it with the kit from Novak.
I think the 205 is a little wider than 17" at its widest point.
If the d300 is out, what about an EB d20? Smaller, lower gears and stout as it's also gear driven.

A 205 has after market lower gears available. I already have 5.89's in the axles. I am looking at the Wild Horses option of the 203 and 20 doubler. It should have enough gears to do what I need it to do. Any thing is better than the stock tranny in this thing. I figured the NP 435/203/20 combo to come in at 37.5 inches. My stock set up with a slip yoke eliminator is 39 inches... Wheel base is also an issue for me. I am not jumping on the "Let's stretch your jeeps frame band wagon". I like the shorter wheel base and actually am limiting my tire size to 37's. I don't want to get ridiculously top heavy or have the ability to stand it on the tail gate every time I climb a hill...
I am already running a drivers side drop 44 front end. It is a ******* offspring of wagoneer and dog parts. I went a little different way to get the 5x5.5 bolt pattern. Pretty much any Ford t-case should work, but I am looking at the 20 or the 205...

My experience with the 44 front is that they are weak for any serious bashing. Maybe Ok for a rock crawler but I broke a bunch of them just out 4 bying. I broke one in half on a little jump that I got maybe 3 feet of air, and wrung the guts out of a twice when the the front tires did a couple wheel hops under power. And I was running stock 7.50x 16s
