My yj wrangler build thread 304 383.

Alright so I have been in the process of building a jeep for awhile. this jeep



I have a 383 stroker motor with truck avenger carb,

But recently scored another jeep on craigslist the one below. it has 38 inch tsl Dana sixty in the rear Dana 45 in the front its got a 304 amc motor with a Manuel 3 speed tranny... I am thinking of yanking that motor out and welding in my chevy mounts to this jeep and putting my 383 in it. I am swapping bodies with the above jeep as well.

















closed knuckle don't like that





so in two weeks I will be pulling this body off and putting everything together. I need to hook up the steering or figure out a solution to all the steering. I also need to figure out if I am going to try and run the 304 or if I should yank it and run the SBC. Got a lot of time to figure out what I am going to do. but when I get home from north Dakota I will start working on this beast.

I still have to get radiator, I need to get my transmission transfercase for the sbc and msd distributer, ignition, power steering pump, bake lines fuel lines boy a lot of work to be done but it should pay off when i have it sitting on 38s.

That is some old *** axles with small splines if they are stock. Still need a high steer set up for it.
Is the rear springs setting solid on the perches?

And that dont look like a 60 either..
Front is a 44..

I dunno I need to go pull part numbers my father in law picked up while I was in north Dakota. I was told by two people its a Dana sixty but you never know tell you run the numbers. I think I am going to attempt to see what the 304 has to offer before ripping it out and starting over. Like I said I have a lot of work to do. however if the 304 turns out to be junk I will sell it on craigslist and put the 383 in there. I am thinking the 304 has to be a lot better then the four cylinder I am use too... if the axles turn out to be crap I will replace them and get different ones. but they should hold up to my 383 and definitely to the 304. I am on the market looking for either headers or stock manifolds I don't know if the stock manifolds will put the pipes inside the frame rail or not only one way to find out and that means spending some money.... I ordered a new distributer starter msd ignition radiator they should be home next time I am home.

My opinion would be just to start over in the axle department, that old closed knuckle D44 is not the most desirable either

For the sake of nostalgia- especially if you wake it up a little- I'd stick with the holy AMC 304. Will it be thumpy like a 383? No. But it is pure history and a solid runner if it's not worn out.

How many old threads actually convince *you* to read all 36 pages? http://www.jeepforum.com/forum/f12/length-envy-build-thread-629700/

That rear is either a Ra-15 axle from a international harvester...
Or a GM Eaton.../. I can not tell the difference..
I know the 2 bolts on each side are close and not spaced correctly, but some sites say that is eaton and others international

The amc 304 is usually a dog.

Rear looks like an Eaton which is stout, just not a lot of support for them (I run one). Front is junk. T-case is a d20 that only works with a few Jeep transmissions (t18 will be the best of those).

i would use the 304 for ease of work but if you already have the 383 and a tranny, might as well run that chevy

I don't feel like working on anything at this time so i sold my yj.

The 70' - 71' 304 put out 210 hp (Gross rating, not SAE)

The rest vary between 150 hp (72' - 78') to 125 hp. (79' and later)

Not worth messing with.

On those criteria it is not worth it. But with a few wake-up items and a craving for AMC nostalgia the motor is ok. On the basis of cool factor AMC blue paint it would be hard to resist for me. Even though the 383 will always win in the HP department.
To each his own. Admittedly, my interests lie in the fringes: straight sixes, aircooled VWs, and the nostalgic (I am still disappointed that Hot Rod magazine's 80s prediction of the 231 Buick V6 being the small block Chevy of the future didn't come to pass...)

well decided I am going to get the 304 going put drive lines in it push it out the door and make my money back on it. I only bought the blue one for 1900. I am hoping once I get it running I can sell it for 3500 as a toy we will see.

the rear end is a chevy eaton. looked it up did some research.
Or trade it for a yfz 450 quad.

the black one will go under the knife after I sell the blue one.

I have already been collecting parts for a long time.
