Jeep Dana 300 Flipped

[superswamper_800]

I had a question for you Jeepers, nomaly Im hangin around the Dodge section but have a question for you guys about the 300. Ive got a 318 V8, just swaped in a nv4500 29 spl and am looking for a t-case that will hold up for a while. How much power are you guys putin though these dana 300's? I know in my old scout I ran a 304 v8/t-18,dana 20 SOA, 1/2 ton axles, and 35's just fine, but now Ive got a 318/nv4500/?????, SOA, 1 ton axle w/ 4.88, and 39s.
Thanks

you should be fine. some of the guys on here have them behind the AMC 401s. if you are going to ever step up to a big block, i suggest you go with an NP205. good luck.

I think you would be fine with a Dana 300.Swap the input for a 29 spline.You can do a 32spline rear output if you want to.The nice thing about Dana 300s is you could build it stronger as you go.

Ya if I do a Dana 300 Ill be gettin the rotation kit, Low-Max 4-1 kit, rebuild kit and shift kit from JB Conversion, everything they have to offer for the dana 300 for my NV4500

[superswamper_800]

The only problem is how do I accually flip the case to drivers drop? What rotation ring or adapter is needed? Or is it the same round 6 bolt pattern as the NV4500?

[superswamper_800]

This should be the same round 6 bolt pattern right?

I flipped mine temporarily behind a 727. The shift rails hit the trans pan and the shifter linkage needs to be cut off to clear the trans mount. I've got a great lakes clocking ring, so hopefully I can clock it where I need to to clear the pan and get it flat.

From what I can tell, flipping will make the t case 5 bolt not 6 as one hole is about 5mm offset. Not sure what happens with the clocking ring, we'll see when it arrives!

If you need a drivers side drop and you need strength for high hp-tq by the time you buy the d300 and upgrade with hd shaft, flip kit and 4:1 you could have bought an Atlas or Stak Case. I know it's more money up front, but a much better investment in the long run.

Hopefuly that wont be a problem with the NV4500, theres alot of room for me to play with. As for the shifter, Im just gonna cut as much of the stock braket off as I can and have some push/pull cable shifters made localy. Googled this and this guy used the same driverside flip ring from novak that Im looking at and it seems to clock it just fine for me (at least for his setup).

Now that ring from Novak says that its good for the NV3550, which to my knowage is the same round 6 bolt as my NV4500, because I know they offer the np231 with the NV3550, and the 231 and 241 have the same round 6 bolt and my current case is a np241, So it I think it should all work, I THINK!!

As for the 5 bolt deal. It shouldnt be like that with the adapter ring, because with the ring they have the room to tap the holes just about anywhere. At least thats how I see it, plus they guy in the link above didnt mention having any problems, not sure I still have to call JBC.

Well Ive made a long ass list of transfer case options, the only one I didnt check out was the Stak, because Ive only heard bad about them. I want to slap a Atlas 4 spd in there but built to my specs it comes in well over $3000.-, so I steped it down to the 2 spd and built to my specs it comes in well over $2000.-. With a Dana 300 I can build a bullet proof case( - the billet aluminum case) for under $2000.- . I can get a case for damn near free now, put all new seals, gaskets, and bearing in it for $100.-, If this ring from Novak is the right part, thats only $123.-, From JB Conversions Ill need the 29 spline input shaft and possibaly the retainer ring, so the most Ill spend should only be $300.- or so, hoping I only need the input shaft for $175, Probably have to upgrade the rear output right away only because I need my stock speed senser working, so at most $475.-. So all that there comes out to $998.-, A little over a $1000.- with tax and shipping, tack on the front output upgrade, at most $235.- and some 4 to 1 gears $600.- and your lookin at $1833.-, Still a few hundred less then the atlas 2 speed and even if I were to get an atlas Id just save a little more and get the 4 spd.

It'll clear a 727 when flipped to drivers side as LNG as you use a narrow driveshaft.

I used the go2guy flipped 300 clocking ring. It works great.

You'll want the upgraded output shaft. Trust me.

[Oze30]

Is go2guy still around? Where can i get a pic of it?

Do I need the holes to go clockwise from the countersink or counter clockwise?

[Oze30]

Got a Great Lakes clocking ring, but they still didn't fit. So I unbolted the adapter and then drilled it using as many holes as possible to hold it. (I think there's 7 or 8 bolts/nuts holding it on).

Advantage of that is, I managed to get the Tcase parrallell to the transmission mount on the adapter! Flat is flat is flat!

[matts88yj]

Go2Guy is still around. I picked up a clocking ring for my 300 from him and it came out very nice. I built my 300 up and it was the first transfer case I ever tore apart. It was pretty simple and I figured the only way I was going to learn is by actually rebuilding it from the bare case up.

To keep the 300 happy, run deep gears in the axles if you can. That will take a lot of the stress off of the 300 itself and put it in the axles where you can get stronger components. With that setup you should be good to go.

I am looking at doing the same thing. I already have my 300 built up with everything from JB Conversions so tell me if I am wrong.

The rotation kit that they sold me is fine for flipping the case and all I need to do is change the fill and vent holes ?

Unless you specified, you just have a standard clocking ring. I'm not sure if they sell one for flipped 300's or not, Go2Guy does.

You'll need a flip kit. There are two methods of flipping a Dana 300. One moves the shift rails to the "top" of the case, the second moves the shifters to the top of the case, leaving everything else stock.

I prefer the 1st method, and had mine built that way. The 2nd method requires you to trust the seals around the shift rails to hold fluid in a manner in which they were not designed. There are people who have had good luck with this method, but my luck with seals tells me to avoid it like the plague *shrug*
