Torsion bar diameter for 440 swap

-
Better off building a stroker small block. Fits better packaging wise, lighter weight, unless WoW factor is what your after.
 
I used a 1.03 in my Valiant, a big sway bar moved the battery to the trunk and used as many aluminum parts on the engine I could and it handles quite well on the road. Never tried auto crossing it though.
 
Is it a track car or street car?

Street car use 1" minimum

Track car then the smallest you can find
 
My 1.03 bars have never given me the impression that they were too big,(or have they,see below).
My SBM 68Barracuda scaled at;............. 1750/1717r=3467 total,
with me in it, in track trim, with 200pounds removed.
Here's what I took out;
Exhaust; 3"TTI/Dynomaxers(72), rear seat(64), heater(16),.....total 152pounds
front bumper(30), sway bar and skidplate(18),.........................total 48pounds
As you can see only the 48# came directly off the front, the rest is between the wheels, with about 100 of it right in front of the rear wheels.
If I had to guess, in street trim;...............1850/1817r=3667
but the rear seat never went back in, so... 1850/1753r=3603...That was 2004, and since then I
have gained 25 pounds, so guessing now; 1868/1760r=3628

But; I gotta tell ya that at my slightly lowered rideheight, there is very very little preload on those PST bars. So little, that sometimes I am cornering on the poly bumpstops. And when I hit certain speedbumps in my town,, POW! the bumpstops jackhammer the front straight up.So in that light, I think I could run LESS bar, and more rideheight, and let the shocks handle it.
but no way am I gonna do that,lol. I just slow down for those, or lower the tire pressure on Friday afternoon, cuz, you know, I love to smash those speed bumps when passing the tuner boys crabbing over them while holding up traffic to do it. BadaBOOM! Ya ok, so that might be dickish, and I know it, so whenever I do it, I lay on the gaspedal too; why be a half-dick, when you can be all-dick. I my defense, they all know me.
 
.094" is oem

OEM is .890" for big block A-bodies. We have two sets. I would like to go a little bigger, but I'm not going to spend any money to get there. I've been happy with the set that my son has in his '67 Dart (440/4sp convertible). Shocks are nothing special, but the car also has a factory big block sway bar. I'd like to have some .920" or .990" and use the .890"s in the 340 car instead of the .870"s.
 
James, do the 1.03 bars not fit the early A bodies? When I go to choose them for my 64 Valiant, it says "does not fit"

Yes they fit A Bodies 1962-76. I will make the correct on our website ASAP.

Thanks

Thanks James! I thought that was right, but then, I'm wrong on a regular basis so who knows? I'll be getting a set before long for my 64.
