The SS springs right now have a clamps in the following positions:
Passenger side: 2nd leaf in front of axle
2nd leaf behind axle
Driver side: 1st leaf in front of axle
3rd leaf behind axle
In addition to removing the rear clamps should I add any up front. I think there are still 2 leafs on each side that are not clamped in front of the axle.
I also forgot I have a pinion snubber installed and it was tight against the floor. Not sure if this is a good thing or a bad thing?
With my cheap sears angle finder it appears the rear sits pointing upward. I will have to get a good angle finder like the Comp Eng one I have seen in the summit catalog to get some accurate readings for pinion angle.

90% of making one hook is in the front end ( especially with radials)........It needs to be really loose with loose shocks (I've had good luck with Cal-Trac shocks myself)......I like to use poly lower control arm bushings, heim joint strut rods, and heim joint upper control arms......and then shoot for 5" of travel from rest to all the way up........ After the front end is taken care of, I like to run a pretty stiff set of leaf springs....the faster the car, the stiffer.......and as mentioned, clamps on the front halfs along with good adjustable rear shocks so you can control body seperation........I shoot to have just enough body seperation that you can just see the body move away from the wheel about an inch......If it seperates more than that with the shock on the tightest setting, it's time to start adding clamps onto the rear spring halves......   The worse the track is, the looser the shocks will need to be to get that 1" of seperation.......and, obviously, the better the track, the tighter the shocks will need to be..... Throw the snubber in the trash.  If a leaf spring car is squatting on launch, it means that the leaf springs are worn out and need replaced. Wayne

碨lapper bars on mopars创创创创
Yep ,i like it when people tell me something wont work.It motivates me to prove that it will .My car lifts front and back on the launch and dead hooks everytime with the $35.00 40 yearold Foxcraft slapper bars .I know lots of guys at the Nostalgia events i go to that cant 60' as well as me with coil overs and ladder bars on 10.5 slicks compared to my Slapper Bars and 8.5 inch slicks with 15 psi in them .Could i have been like the main stream and went with Caltracs or SS springs ,sure but wheres the fun in that  .I am in the mid to low 1.5 60 foots now and im gunna prove to all the nasayers that it will hook a 1.4 60 foot with this lowbuck junk i have with the Powerglide ...

I hope this video link works. http://www.youtube.com/watch?v=-OZ17x55z5cIt is my 5th and final pass of the day. 1.72 60' time. Watching it closely it appears the car picks up...then drops...then lifts again. I think someone mentioned earlier that I may be getting hook, then spinning, then hooking back up. What do you think? At this point the following are what I am looking at doing in no specific order. 1. Check and adjust pinion angle to -4* down if needed. 2. Remove clamps on rear of leaf springs and clamp all leafs in front of the axle. 3. Caltracs 90/10 front shocks 4. Rancho adjustable rear shocks (if anyone knows the right part#, please let me know). How does that plan sound?

Here is the type of video you need to get an idea of what the car is doing at launch.] http://s892.photobucket.com/albums/ac129/str8liner/?action=view¤t=2007_09080002.flvThat car is a completely stock suspension with CE 3 ways on the front. Has no clamps on the drivers front, 1 clamp on drivers rear on 2 segments and pass rear on 2 segments and all the segments on the pass front clamped. I had much better luck with our car when I limited the separation of the rear leafs with the clamps. Each car is different and thats why you need to try things. Pinion angle is 5 degrees down. and no pinion snubber. 60 footed 1.43 the other week when I drove it. Dead hooks every pass.

Measured tonight and it looks like the trans is pointing downward about 3.0 degrees and the rear is pointing up 3.0 degrees so they appear to be in line. I am measuring off of the flat surface of the yoke on the rear and the flat part of the universal joint that goes into the trans.
It appears they are in-line so that would mean my current pinion angle is zero...right? So I would need to add 4-5 degrees worth of wedges to the rear to get the angle on the rear to read -1.0* to -2.0*....right?

There used to be a guy named Jimmy there that would head into staging with few cool ones in his 10 second Chevelle

If the weather is decent, I'm probably going to race at Mason Dixon on Sunday or there is a very remote chance of going to Island on Friday night. I'm going to make the following changes and we'll see if there is a measurable improvement. #1. Disconnect swaybar. (Hey, why not, it's easy and it's free.)  #2. I'll take the pinion snubber off. (Again, free and easy.)  #3. I'm going to remove the rear spring clamp and add clamps to the front part of the springs (Super Stock). I have some questions about this process. Do you clamp all of the front half segments? There are seven on the right and five on the left. There is only one factory clamp per side. If I'm to clamp all segments, I'll need to add ten clamps total. Mancini sells them for $44.95 for two.  So I have decided to make my own and I already made one for mock up tonight. I can use it as a pattern to make more but I'll have to go buy some more hardware, so I'll need to know how much hardware to get.

Correct 
As for ideas on your traction problems. From the vids you are hooking and slipping.
With the SS springs I would lose or drop the snubber contact adjustment first and tune the suspension from there.
See what the SS springs do on thier own first. Then add tuning devices.
From what I see in your vid , it appears you have the driver side torsion bar cranked up. That will add preload to the right rear. With the SS springs you shouldnt need that.
If thats the case and true from the vid, witch it may not. You cant trust all "Vid perceptions":
You could be preventing some needed frontend suspension weight transfer.
If that torsion bar is indeed cranked up Id lower it abit. As far as clamps I wouldnt use any extra ones on the front driver side.
Actually, I think you need to start from scratch without the snubber and clamps and go from there.
Your MPH of 115.8 tells me you have a 11.50 ET ride, you just need a 1.56 or so 60 ft.

The front starts to come up but the back end of the car doesnt do a thing.... first off you dont have anything to adjust... you need a good pair of shocks front and rear... adjustable ones... the back of the car sits too high and you cant get the front up high enough to get over the CG of the car...clamp all of the fronts... that will give the body some movement... but those springs look like they are too tall for the car.... your front end looks like its setting up high also which gives you less movement before the shock tops out

Thanks for the feedback on the video. I know it wasn't ideal but it is the best I have at this point. Pinkduster - I will be interested to hear how your changes work out...especially ditching the pinion snubber and clamping/unclamping the springs. Sport440 - I have the torsion bars adjusted per the original factory service manual. I think it called for a 1" difference between their 2 measuring points? It's been a while since I last checked them. I do notice the car sits lop-sided from the rear but that is the SS springs. Back in '06 I installed new .920" diameter t-bars which are what Mopar says to use for an E-body w/440 or Hemi. I wonder if I would be better off putting the old original small block t-bars back in the car? Mr P Body - I installed the MP SS leaf springs back in '06 as well. The are Mopars ending in 460/461. It is what is recommended for a 3600lb. E-Body which is what my car weighs. Are their any tricks to getting the car to sit lower in the rear.? If I remember right the front hanger has an upper and lower mounting hole for the front spring mount. I think I have it on the lower one now so moving it up should lower it some...I am just not sure how much. By the way...here is a link to all of my runs on Saturday incase anyone is interested. http://www.youtube.com/watch?v=jwIxdsO3I8A

Ron...I put an 8" ATI in it a couple years ago but last fall I switched back to my original 10" Turbo Action. I like the 10" much better on the street and the difference at the track was not significant enough to keep the 8" in it.
So when it comes to front shocks you want something that will extend easily and compress hard? When it comes to the rears you want something that is harder to extend in order to keep the rear from rising. Do I have this right?
Yes 90/10 cal shocks are night and day to those slow extending comp ones.
and yes to the rears.
