Drv side has space the thickness of a nickel between spring and lever.
would the bigger gap help with a harder hit ?
I have just a slight "air gap" on mine on the driver side,,might open it up some if you have found good results..??
Doug
Opening the gap would definitely cause a harder hit.
The thickness of a nickel is very small and allow the bar to work in a non violent way.
Soften the shock setting allows the tire to work without spinning.
Just trying to not over power the hot,greasy, sun drenched starting line this time of year...

Randy, Looking at your youtube videos, imo, it looks like the car is porpoising ie., rocking front to back after the initial hit, unloading the slicks. - You can hear the engine loading differently as it bounces around. http://www.youtube.com/watch?v=J_TSf9u0o3cHave you ever checked to see how much travel are you getting out of your front end before it tops out? Super Stock springs + 30" slicks can make for a pretty tall rear end of the car. I have read comments from mr p-body and others that explain that this kind of raked stance & rear height yield a tall center of gravity. This higher CG makes it more difficult to get the car to rapidly transfer the weight to the rear. In essence, the energy is wasted instead of being utilized. Swapping over to some stock ride height or - 1" Calvert Monoleafs + caltracs would lower the rear substantially. Lowering the CG would aid in getting the weight and energy transferred rapidly and firmly planting the tires. Ever considered lowering blocks or different front hangers for your existing SS setup?

One thing that I SHOULD have tried for my lousy 1.60 60' times,was softening up the shocks!  They were set @ #9 position..or as stiff as you can set them! Probably should have tried #7..or even #5,since the starting line wasn't so good! Too busy fooling with carbs..and jet changes, in the blasted heat!   
Randy, I would start with working on what you have now
and see if its optimized(which I doubt)... everytime
we/you go to the track you play with the engine...
I dont know if you have ever spent a day tuning the
chassis... like I told you before, you need to lower
the back end some BUT if I remember right you cant
because the tires crash... well we need to look at
getting the tires to clear(move them inboard some)
and this might be where the ladder bars come into play...
its been a while since I've looked under there
to see whats what.... maybe you should bring the X
over and we spend some time eyeballing under it ...
I do remember your shackles are out of wack(angle)

Dont matter to me... I'm here all the time(I'm boring) just give me a call before you swing by..... also when you have the tires off measure the total clearance you have in the wheel well

Al...your X sits MUCH higher than mine! I think mine is pretty even..front to back! What size are your street tires? I run a 295/65-15 on a 8" wheel..4.5" back-spacing. Thanks for the pics!...NICE! F-8..or F-5 Green? 
Randy when you are doing some measurements take a
reading from the axle flange(drum) to the back for
clearance to see what BS you can get away with

On my 68 GTX I ran 15 x 10 with 4.5 back spacing and 28.5 X 10.5's with no problems. then 29.5 X 10.5 was still ok but when i went 11.50 X 29.5 (30.5 high) I had to cut fold over the flange lips now a 5 backspace maybe would not have to?? And that was without relocating the springs!

Brent...My bad! My memory needs a darn tune-up! I could have sworn I had the Rancho's set at #9!....they were actually set @ #5...maybe too soft,and reason for the porpusing! #5 is my street setting,by the way.

Randy, mine has Caltracs & monos with 295/65 M/T DR's and it hooks good with 720ftlbs of tq  Chip runs the same suspension & tires on his Cuda and 60fts in the 1.30's with his 572 Hemi  Brad H also runs CalTracs and 295/65 M/T's and 60 fts in the 1.40's My vote is to not cut the car up, use a bolt on traction improver and use a 295 DR Ron Ps. On a side note ; i'm wondering if those a-body SS springs might be causing some type of problem ? Are the rear shakles facing forward with the chassis loaded ?

It's got to improve my 60's over my current SS spring set-up! Am I correct in assuming this? 
Thanks in advance for your opinions! 
On an 8" rim? Do you remember what the back-spacing was? Thanks!
