i have a 76 cj5 i have a sbc 350/sm465 im swapping in,in the spring i was thinkig of goin with an np205 t case.is anyone running this combo.

my question is how long will my driveshafts be with this combo.ive heard its not goin to leave me with much of a driveshaft.specially once lifted.is the 205 really worth installing or should i stick with the dana20 thats there now.

Just an educated opinion here. Do not do it. I have, and it worked for several years but I literally had no tube on the rear d.shaft. I just butted them up and welded them. I had the rear back about 2" is all. The engine was centered and fit where it should in the compartment.

Even if you shoved the engine ahead, and moved the rear back a ways further, it will be real short.

At that time my suspension was not real long travel so it was alright, but I wouldn't do it now.

FWIW-ROB

thnx for the input think ill stay with the dana20.not sure if i wanna use the sm465,pondering the idea of a t18 but not sue at the moment which one to go with

If you've got the SBC/SM465 combo, don't go looking for a T18. Adapt the SM465 to either a Dana 20 or a Dana 300 transfer case and call it good. Of the two, the 'edge' goes to the 300, because of better parts availability in the aftermarket. It also will allow you go use 4:1 gears from LoMax or TeraLow. However the Dana 20 is a good transfer case for the CJ, so don't walk away from a decent deal on one. You can go with 3.15:1 gearing, twin sticks, etc.

The NP205 is a huge chunk of iron for a CJ5.

how about just stretch the bitcvh and don't worry about it? you need longer WB anyway

the jeeps already got the dana20 in it.stretching it would be beyond my skill, i would imagine it would be hard to do.
