Help deciding on Street/Strip torsion bar size

It all comes down to which is more important to you then you can favor that way with the torsion bars 86,88, 90 strip, or above 90 for street. As said before it's a compromise.
 
So I just want to say thanks to all you guys for the info.
(.96 - 1.06 to stiff for the track)
(.82 - .84 not so good on the street)
(.88 being stock is probably a safe middle ground)

From the feed back I've been getting maybe this is one place I can save a couple bucks and reuse the stock set I already have? Don't know what size they are but was an original POLY car no/AC.
Anyone had a problem with reusing 50 year old bars?
 
I found this in an older post, Looks like i have the 776/777 bars so .88 in diameter.



A 66 Satellite with a v8 would use 776/777 bars for standard suspension, 778/779 with heavy duty suspension without swaybar or 780/781 with heavy duty suspension and sway bar. my 66 Satellite with a poly 318 and A/C had the 776/777 bars in it. If you have the build sheet that makes it easy.

Just looked at my stock bars and they are 780 and 781 so according to chart .920
 
in that case, keep running your stock .092" bars for now and swap those shocks out for Bilsteins or QA1's. Then drive it and report back. Then after 100 miles or so, if you do upgrade, I would go to the .096" size and call it good. Mancini and Firm Feel both sell the .096" size as the improved handling size for big blocks (which is one size up from original OEM stock which most of us know was a bit too light for good handling). I don't think with your minimal 5x drag race per year that the .096" bars will make your track performance suffer that much and you'll benefit more with the rest of the suspension goodies you already have on the car.
 
Just finished up my winter suspension project. Some of the parts used smaller bars Firm Feel, Strange double adjustable shocks coil overs Riely motorsports A arms, Calvert 90/10 front shocks new tie rods and bushings, existing Strange disc brakes all four wheels, corner balanced, IMG_0389.jpgIMG_0392.jpgIMG_0393.jpgIMG_0394.jpg

Nice set up. Do you prefer the O Riely motorsports A arms over the QA1's stuff. How do you think the rod ends would hold up over time?
 
i was surprised at the number of racers that don't believe soft bars help the launch.No matter
which bar you have for any given ride height the bars will be loaded the same,small bars will
just be twisted a little more?
I would probably pick a bar that would afford better ride and safer handling,.96 or 1.0"

Iron has no fatigue limit, so as long as they weren't damaged or had a torch to them, they'll out live any of us.
 
Well all I can say so far is this is it. Re corner balance next week and then try it out. It really needed attention and all these parts came from good sources. I know from what was taken out of the car it will be a marked improvement My goal is straight line in the grove racing. Nothing more nothing less. Once it dries out I will take it test and tune either in Sacramento for Sonoma at the end of the month. I will get some pics and see how much time I save. I know it will be better.

Canyon what size bars did you go to?
the bars are 875
 
So Going to stick with the stock .92 bars for now. Should work fine and if I remember correctly it drove fairly well on those (with the POLY) Even without a sway bar. So with the big block, aluminum Heads, Intake, Water Pump, Bogeson Box, Tubular cross member, Control Arms, Aluminum radiator, Battery in trunk, With a added sway bar, Should actually handle better then stock and hopefully manage to get from A to B respectfully.

I use an .875 bar

You're going to upgrade the shocks though, right? You will notice a big improvement.

I have done that see pic 90/10 calvert front and strange double adjustable

I have done that see pic 90/10 calvert front and strange double adjustable rears. I will have more pics soon.
