To me it really depends on the power. If you have a lot, most guys limit the downward travel to keep the front end down. real "springy" torsion bars for for lower powered applications were the car needs help getting the weight transfer on the back tire. Another issue is a lot of street use and potential oil pan damage. Looks like you have a big block in a B body, this usually works good. I would stay with the 0.960 IMO.

i am not sure what spring rate is on the rear. this is my first ladder bar car. and trying to learn it all. thanks guys for your help. any info or advice is greatly appreciated.
Here's a great Web site to learn............Billy recommends having the stiffest bar in the right front and the weakest bar in the left front to get equal tire loading........

"Stored Energy" is what your looking for and a .920 bar will not do it. You want the newest and the smallest bar you can get your hands on. In a perfect world you want the bar turned all the way up just so the body is just off the bump stops (and that is with the bump stops shaved down to less than an inch thick) You can always control compression and expansion with the shock and limiters. Just my opinion.

While I like the idea of stored energy! Ive seen the effects of to small of bars. The smallest isnt always the best.
Did I ever tell you the story about the 3 bears. mike

I`m running 30 year old 6-cyl bars and they seem to be working ok.
See, Thumper knows the story about the Three bears Too!
As the 6-cyl bars Arent the {thinnest} bars available.
There are {Drag bars} thinnest. And {6-cyl bars} thicker. And {318/340 cyl bars} thicker yet.
So its not always about just getting the Thinnest bars you can get
Its about getting the bars that are more optimum for your combo. mikre

Lets talk about the B body first.... B Body are hard because Mopar no longer sells the old P5249156 .840 bars. I would look and see what the after market has. B Body's can be made to work very well but the learning curve is long. You have to have a very consistent engine,trans and rear suspension to be able to fine tune the front suspension. Trying to do this on a fresh chassis is hard to say the least.
Here is a picture of a customer of mine. Chuck Steinbeck has ran this car in D, E and F and has done very well but 10lbs and a 1/2 turn on his shocks makes a big difference. IF I remember correctly these are the some .840 bars.

A body cars...... I believe A body's are a little easyer to play with. Shorter wheel base....less overhang on both front and rear plays a big roll. When Darren Smith (last years world champ) was building his Dart we went through about four sets of bars and a few others that were home made. ( ) We played with spring rates, tapers and everything that we could think of. We learned that you can not compare the spring rates of a coil spring to that of a torsion bar. I thought that was strange but we came to the conclusion that the length of a torsion bar and length of a coil spring (if you unwound it) plays a big roll in spring rates. The bottom line was.....for a very long time Darren ran the MP .840 bars and they worked very well.

My old street car (iron headed 440 Duster) being a street, strip car, I ran the .870 bars. This gave me good street manners and yet, when I pulled up hard on the front end....with my hands....the front would rise over seven inches!! Most cars will never do that. The things I do not like about old, used torsion bars (junk yard 6 cylinder bars) is metal has a memory. It has a natural state that it wants to stay in. When you have used bars the memory or the spring rate start to go away. A new "happy" bar, when installed and tighten up wants to raise the front end up but the weight of the car keeps it down. When you launch the car the momentum and the torsion bars try to pick front end up and put more weight over the rear. When you have week bars....the bars don't want to go up....there is no "spring" left in them so you get no help at all. I will say this, every car is different and acts different. Sometimes older bars do work in a car but I have to ask my self why?? just my
