Quote:Yes you can
sorry, it is a 72 demon small block 340.
so with it being a a-body i can use the standard length shackles?
The 1962 and 1963 B and A bodys had a 20 inch front segment on all leaf springs, Mopar decided to lengthen the B bodys in 1964 to 22 front segments, why only the Engineers know 
Those springs work awesome for drag racing

The rear bushing on your SS spring require a (7/8 o.d. x 1/2 i.d.) bushing. A-body shackles bolts are .50" shank compared to the B/E which are .5625" or 9/16" shank bolt and use a 1.0" o.d. bushing.
If you are going to use a longer shackle, make sure they accomodate the smaller 7/8" bushing (Moog K7309 or Rabestos 576-3026) found on the SS springs.
Just curious, why or where a longer shackle is required?

My bad... Shackle / hanger, same thing?
Quote:Everrything new on a race car, especially Mopars
so this would be a trial and error on different length shackle?
is trail and error Test, test and test some more My old bracket car, 1969 Dart 440 BB with a 727, liked the single rear clamps on the 002,003 to be directly behind shock plates, my freinds 340 NHRA 1971 Demon wanted them halfway bact towards the rear shackle almost like the stock clamps where 
BTW, the 002,003 will raise the rear of the car up quite a bit, make sure to check the driveshaft to pinion shaft angles before and after, correct as needed

Some of us cheap guys still use it. Quote:Quote:

Hey whats wrong with 60's tech ??
I agree that they mean use the longer front hanger not shackle. I did use the stock shackles with my 3400 lb SS springs on my 63. And I actually bought the Mr Gasket shackle kit with extra holes in it to use them and raise the back of my car about a 1/2" as it was actually a tad lower then I liked. I cut them off and painted them black to make them look like the stock shackle and they made no difference at all in how the car hooked. I use just SS springs and the longer extending MP rear shocks. Yes they are cheap 60's tech as they have no adjustment at all. But they work ok for my street car as it hooks fine and in running 10.70's its had a 1.50 best 60 which is not great but average for a leaf spring car with basically all stock suspension. It works for a low budget like I have been on for a while. Ron

No problem but just wait till the "I can`t get my ss springs to hook" post or maybe not as some run well...........

My old Duster ran a best of 9.82 many many years ago. My Son Matt sitting in front of the quad is now 26. With today's technology I wouldn't put super stock springs on anything I planned to take to the track.

Come on John, that's all I have on mine, with wore out stock shocks too. And you've seen how my car runs!

You are right BUT by time you spend 200 dollars for Super Stock spring why not upgrade. Back when I ran Super Stock springs shock technology and track prep were nothing like today. My Duster would hook like a son of a gun Friday nights but come Sunday when the sun was on the track it would spin. And we are only talking about a high 9 second car. Look at what these cars are running today on Caltracks. I guess Super Stock springs have their place.
My car is slow though, only mid 10.30's...

I like the challenge of making the best of what I have to work with. That's part of the appeal of the very rules restricted IHRA/NHRA Stock class racing. While they do allow Cal-Tracs, I have to watch my budget. I have gotten my car to work well on just SS springs and 9" tires. But the events I attend normally take care of the track better than some local, weekly ET events as well.

No snubber.
Unless you're running a transbrake.

My junk`s on C-tracs and sliders w/the 25" ft. segment and have only made 1 crap pass last summer(which I never do)at an 1/8th mile track which netted me a 1.46-1.48 iirc 60ft and a 6.20 at 111+ mph pass. Considering I`m lighter by almost 150 lbs now, on slicks w/lots of changes I don`t think a 6.10 at 112+ and a 9.6? is out of range and will hopefully get out there within a month or two..........

Wow my car is 700# heavier than yours with the same 60'on ss springs/slapper bars.I am just saying because a heavy car would need more clamps,tunning depending on the P/W ratio.I was able to find there limits.
