Oh thank God, I won't have to worry about that then.
My no adder ladder bar small block has come up further than I wanted it to and usually slows me down .01. I try to keep notes now and a few clicks on the front fixes it.
You have a transbrake ?
That's probably a very light 400 ish pound engine too
tranbrake and heavier R3 block.
Oh cool, I need not worry I suppose.

Like PBR pointed out, a few clicks of the adjusters on the front shocks can clean up the big wheelie. That’s why DA shocks are so important. You can adjust the rebound without changing the bump and vice versa. That’s a big tuning help too.
Yeah I better go get some then.
I only have single adjustable on the front right now but after I get rid of my 20 plus year old rear shocks I’m going to upgrade the front shocks.
I have new 90-10 Calvert s are the worth a **** at all for just a season ?
My son has five years of weekly racing on his. Maybe a year or two more. I have strange struts on the front of my duster.

Has the “snow giant” made it down the hill yet? I was at the shop today and we were discussing snow and whatnot.
Yeah I got there at 11:45, it's pretty treacherous up on that hill, lol.

you'll think it's crazy, but it works for me. Passenger side is adjusted to contact the spring. no preload. drivers side i slip a Quarter (25 cent piece) under the adjuster until it contacts the coin, then i push the coin out. The Ranchos out back are set on 9. Torsion bars are set. drivers side three time tighter than passenger. 80/20 shock drivers side. 90/10 passenger side. It pulls 1.42 60 ft. Mind you this is with a 3000 stahl. It hooks hard and does not slip.

Forgot ...The front of the bar is in the top hole. The bars don't hit harder. but they do react quicker.

Yup Caltracs don’t work. Never had em on an a-body but on my Belvedere
3750 lbs with 9x28 slicks. 3.91 gears and Qa-1 shocks.
It too some time to get it all working correctly
Best of 9.88@ 135 mph with 1.38 60 ft

I don't know but I have a friend who has a SA/E mopar that runs 1.30 60 ft, that's on a 7" slick with little more than 500hp. He's on Calvert split mono leaf springs and Caltracks that appear to work.

That’s why I asked about who said they didn’t work. I know I didn’t say that.

I'm putting the Calvert suspension on my 64 Fairlane, I think he will help me set it up.

Love that photo!!!! May I make a suggestion? The front end of your car is twisted. This can be adjusted to come out even easily. The Cal-Tracks will work even better. I fixed this this way because mine did it.
70/30 shock on drivers side. 90/10 on Pass. side. Find your lowest ride height even side to side in the front. My ride height is determend how high it has to be to get in the trailer. Last, increase the the spring tension on the driver's side torsion bar. I'd start with 5 full turns and go from there. There is a balance point of how tight on the driver's side and how loose you are on the pass.

They work , my Dart ran its best 60ft 1.40 on Super Stock springs but it was inconsistent , since adding the Cal Tracs many years ago my 60 its are consistent last time out 1.59 ( deep staging ) on four runs both lanes. Most times out my 60 ft never varies more than a hundredth.
My mate who I used to crew for with his 3800lb '69 RR has done quite well with c/tracs/mono's and 9-ways with rubbish 15yr old 90/10's of some make, not earth shattering 60ft's but a best of 1.42, and 10.30@130, traps at just 6200-ish, low 1st gear in 727, 4.10 Dana, 10x29 Hoosier D06@17psi, 2 flats and 7 on the 9-ways, an on track calculated 688hp mild big wedge motor, in full street trim, drive to track and home.

I don't care if you have caltrac's, ss spring or just plan old stock springs.
Put some tires on that you know will never hook! then play with the front torsion bars until you can keep control of the car(spinning straight) with a half track spinning rear tires.
Bolt back on your slicks and i bet it hook! If it don't, then mess with the caltracs.
Try it!
It worked for me.
I'm running SS Spring. Caltrac's were above my price range.
My next set of slick will be smaller, they will hook, and the car will be faster.
Just my 2 cents
