We'll here is my repower program to date.

1984 K5 Blazer 4x4 6.2 Detroit 700r4 np208 4" lift new 35" bfg at tires. I just bought a 92 d250 2x4 auto 5.9 ctd. Also bought a rear corporate 14 bolt full float with 4.10 and a 3/4 ton dana 44 front with 4.10. Still don't know what I'm going to do about a tranny yet, options are a nv4500/np205 or the stock auto in the d250 and a np205. The Dodge is kinda fast for a stock engine and tranny with 176k on it. Here is what I got into it so far.

K5 paid 1250.00
lift pump for the 6.2 20.00
D250 paid 1600.00
14 bolt 175.00
Dana 44 175.00
Total is 3220.00

The dodge needs a ip(leaks bad) @ 700.00-750.00 and the fuel heater is also leaking.

Here are a few pictures.

Great looking K5, can't wait to see how this one goes!! Thats an AWESOME combo, a K5 and a Cummins. WOW.

And one more time. Also I have a nice shop to work in, it's nasty outside.

yea, no kidding awsome, the only sugeestion I have is brace the front of the frame, they are terribly weak around the steering box, o and Id go w/ the nv4500-205 combo

What year did your D44 come out of? The reason I ask is in the 1979 model year all 1/2 and 3/4 ton fronts were switched to Corporate 10 bolts, many do not know that.

The corporate 10 Bolt was stronger than the D44, and you can save a bunch of work by just swapping spindles out.

4.10 is way too steep of a gear for a Cummins, I have them currently in my 79 K20/4BT swap. 62 MPH is flat out at 2500 with no O/D.

You may want to consider trying to trade the 6BT for a good 4BT, plenty of power and a whole lot less weight hanging on the front of that thing, my 4BT sags the stock 3/4 ton front springs pretty good.

Oh yea, kind of forgot, look at what DieselJon is doing for his Sub, good ideas on using the Dodge crossmember to mount the engine!

Thanks, I like the combo also.

Yea I plan on boxing the frame plus what ever is neccessary for extra strength, cause I have to notch the frame for the ac comp.

I also am leaning towards the nv4500/205 combo, It kind depends on cost. It would be cheaper to mod. the current tranny to 4wd, the nv4500 plus all the stuff to convert to a manual will be costly. I have to buy a np205 no matter what out of a 89-93 dodge passenger drop, I think they are the same auto/man.

Not sure what year, both came out of a 86 blazer in the wrecking yard. From what I have read the d44 has a thicker tubing wall. And yes I have a 1/2 ton corp. 10 bolt front and a 12 bolt rear.

I will be running 35" tires with a overdrive tranny for sure, so I will stick with the 4.10 for 4-wheelin in the rocky mnts.

There is a 400 pound difference in the engines plus the bumper I'm going to build and a winch, so your are right there will be alot of extra weight up there, but I will have to beef up the springs and deal with it cause the 5.9 is staying

sixb

Thanks, I will.

My donor is a od auto tranny so I assume it is a 518. Is there a full manual valve body kit for this tranny? That would eliminate the tv cable and simplify things, and I could run my stock np208 divorced. This would save me some money now and I could always switch later to a nv4500 if it fails or I come into some money. Just trying to get all my ducks in a row before I tear into it. Thanks

You can get a rebuild kit for about $40 for the VE, for all the seals....you might try that before you drop 700 on a new pump.

EDIT:

Cool swap by the way!!!

It only took an hour to build a bracket for me to use the factory GM A/C and it took no frame notching or hose changes. There is a pic in my album. I have the freightliner brackets on my engine, but I am sure something similiar could be done with a dodge. I just was not crazy about notching the frame any more than needed. There are brake lines you will have to redo as well if you go that route.
