just getting some thoughts on the idea of swaping a 1st gen cummins 6bt into my dodge demon....
would the .920 solo torsion bars be enought to support a 1000 pound motor ?
or should i go with a coil over set up or maybe even air ride...
other thoughts and ideas ?

I have heard of people doing it with the 4 cyl cummins but never the 6 its pretty long I am sure you would have to move the fire wall way back and to answer your ? I dont think those bars are going to hold up

i can deal with the height of the motor... i am worried about the weight... around 1150 with oil and acc... and the length of the engine... i do like the thought of 30mpg

I think the biggest problem is the height, a 6bt is a pretty tall motor. It COULD be done though I suppose. Personally I think a diesel in a muscle car just seems wrong but it's your car.

OMG, That car has no radio.

For the mpg, why not the 4bt? You'll just need about 150 lb flywheel to keep your teeth from rattling out.
I still have all my teeth! Someone didn't do their homework before building their engine mounts!! But really, the 4BT vibration mostly goes away after 800 rpm. I run mine at 60 at around 1750, and it's smooth.

i havent found any great deals on the smaller diesels... and it seams easier to make more reliable power with the 5.9... maybe i am wrong...

You won't find a more reliable engine than the 5.9 or the "little brother" 3.9 Cummins. The 3.9 can give you over 200 hp and more than 400 ft/lb., and still run a long time. I have heard of the 3.9 running 8000 hrs. untouched. You can find 3.9 core engines for under $1000, and a nice low mile one for less than $3000. How much is a good rebuild on a 440? And how many miles will that last??

You are going to be in for a lot more than you bargained for on that swap. You had better measure one from the front of the intercooler to the back of the bell. Plan on no center in the core support, fire wall and tunnel cut out.
With a 5.9, I agree. Go seek counselling first.

Dimensions notwithstanding, that is too much weight IMO.
Regardless of the T-bat diameter, one [of many] weak points in such a plan is the rear anchor point for the T-Bar.
Hypermiling a /6 can get you close to your mpg goal, and not upset the apple cart to the degree you are contemplating.
Down to just a blue car now.

That is my concern as well. The torsion bar sockets are welded into the frame, which is not the strongest thing to begin with, but does the job just fine in the weight zone for which these cars were designed. If mpg was the ultimate goal, I would be looking more at mating a 90's mopar 2.4L 4cyl to a rwd overdrive manual trans. I know it's been done, mopar 4cyl mated to a toyota rwd trans. A bit more complicated swap but the weight savings alone would be worth it!

mpg isnt the main concern... but its a positive... i guess go with a coil over and tie the frame together and shoe horn it in there... lol

If you want 30 mpg and don't want to destroy what little frame your car has, use a 3.9 Cummins instead of the 5.9. It will be a lot friendlier fit and have enough power and will give you the 30mpg you want. I have a 4BT/727 in my '68 Satellite wagon, and even in cold weather and a blend fuel I can easily get 26. The 4BT dressed out weighs about 30lbs more than a RB eng.
that sounds neat. How about some pictures and info about thrc swap?
