I have a street-strip 66 Coronet all steel car (close to factory weight) with a 440 450 HP, 11 to 1 compression, Trick Flow 240 heads, 727, 2800 stall converter, 4,10 gear 10 inch wide 28 inch tall slick, battery in trunk, 150-200 HP nitrous plate system I spray in high gear at track. I live in a rural area and don't drive the car on the street a lot but like to be able to drive on public roads in the summer. Live about 5 miles from a nice track and drive the car to the track on race nights. On a well prepped track car hooks well. At tracks with no prep not so great. Looking at installing SS springs, not sure if I should replace whole stock spring pack or keep the stock main leaf and add SS spring pack to my main leaf. Also, Car has Lakewood 70-30 shocks on the front now and one is leaking so I will replace. Should I go with 90-10 or 70-30 front shock? Any input would be helpful. Thank you!
 
Are you dead set on S/S springs in particular? There are alternatives like Tri City launchers, Landrum or even Espo. Car sounds like a good candidate for Cal Tracs though which to me drive better on the street than S/S springs.
 
I run the 3400# SS springs with Competition Engineering shocks, no pinion snubber, and 255/60-15 M/T drag radials in the back. The front is Calvert 90/10 shocks with 318 torsion bars. 3600#, full interior, battery still in front. Iron heads. Best 60 foot so far has been 1.66.

I don't want to speak for the Tri City Launchers guy but I was just at his shop last week (because he's going over some heads for me) and from what he told me it doesn't sound like he is making the springs for people any longer. But give him a call maybe he has some.

Thanks for response, I haven't bought anything yet so I can go any direction, Cal Tracs get good reviews, Never was too crazyu on how they look but I'll look at anything that works.
 
What times are you running and do you know what the car weighs? The 90/10's might work better for you with SS springs. What I generally don't like about the SS springs is that they usually raise the rear up and that's not what you want. I've had good results just adding a leaf and I know this sounds weird to most but adding another main leaf with the eye and the rear half cut off can do wonders sometimes. I like for the very front of that to be at least even with the original main leaf's eye, not behind it.
 
I was expecting my SS springs to raise the rear a lot but they didn't. My car sits pretty low, a little too low for me. I think the newer ones are made in a different place and seem saggier if that makes sense.

What's your ET? High 11.90's 12.0's? If so, sounds like they're working. I like my cars a bit on the low side....1" lower than stock with a bit larger size tire than stock. Your rear tires are around 28" (?) tall and it's still sitting low?
 
My 65 car with 3400# SS springs. #P3690456 and #P3690457 All steel car 3600 LBS ruffly. It sits level to a bit low in the rear.Front tires are 27.5'' tall and the rear drag radials are 28.'' I believe you should change the front hangers on the 66-up cars with SS springs.

To me, S/S springs are production parts that have been re-arched, clamped in the front with an added leaf on one side. You could have a local spring shop do that to your existing springs.

Tri City and Landrum are somewhat more customized and/or offer a wider variety tyo choose from but accordingly are more expensive. I believe those are what the NHRA stocker guys used before Caltracs became legal.

Caltracs are probably the ultimate in leaf spring tech. They have a few advantages over 'regular' leaf springs; they're lighter and offer a lot more adjustability. Based on your first post, it sounds like you would want the ability to adjust to different track conditions so they may be worth looking into. They run about a grand, not including shocks. They offer 90-10 front shocks and adjustable rears. Most guys get the whole package since it's not exorbitantly expensive and is designed to work as a whole.

7.82 in the 1/8 with a 1.66 60 foot. I'm happy with how they work but expected them to sit a little higher. 27" tall tire.
 
Don't forget you can order the CalTrac mono leafs in different ride heights, stock, 2in higher or 2in lower.
 
My car with the same springs as Darter6. (Sorry it's on a trailer, needed a parking space).Big improvement over the stock springs. The stockers had too much rearend lift,at launch, about five inches, the shocks would top out and spin. The ss springs fixed that even with the same shocks. Has a small rake, and sits level, contrary to some misinformation out there. Any lower and my slicks would rub.
Best of 1.59 60ft (weak) 11.11 at 122. NOT on these tires.

Beautiful car, Thanks for the info!
 
My Satellite was built as a street car, but many race type mods(narrowed Dana, mini tubs, moved in springs, roll bar, '70's technology). It had ESPO springs & KYB shocks(avitar shows this setup). The car hooked pretty well. It had a fair amount left front lift & twist. Put in some 3300# E body SS springs. The newer Mopar SS springs are different from those of the '70's. Have heard of durability issues with the newer SS springs. I don't think the new ones have as much arch as before either. The 3400 or 3800# would be my guess for you, but I had luck making my own spring package based on mid '70's 3000# spring dimensions.

Great info, Thanks for the help. Do you remember the width of your shortened Dana housing after tubs and relocating your springs?
 
I run the 3400 lb Super Stock springs on my 63 Sport Fury also which is a street car I race a few times a year. They ride better then my buddies cars do with Cal Tracs on the street. My car rides very good with just the SS springs on it and I use the longer extending MP shocks on the rear. Granted Cal Tracs will give you the best 60 ft once you have them dialed in but for a street/strip car I like using just SS springs. I don't set the world on fire but I have run 10.70's with a best 60 ft of 1.50. Its not the best 60 for a 10.70 car but its not bad for a street car. I have considered Cal Tracs to maybe improve my 60 but honestly I don't think I would pick up any more then a tenth at the most going to Cal Tracs. And I am on a tight budget and cant see spending about $1000 dollars or more going to Cal Tracs and adjustable shocks. But I agree they will give a little better 60 ft then the SS springs but I feel the SS springs make a better riding street car myself. If I had a lot of money I would try Cal Tracs because I like to pick up any performance I can real easy but I don't see them in my budget. Good luck with your car. Ron

General question to those that run SS springs. I have a 64' Polara that i'm building for a street heavy/ strip ready car. I see weight numbers all over the place for these 64 Polaras and since my car is not at a point where i can drive it to get it weighed i have no idea what the actual weight is. Car will be appr. 200lbs lighter than stock ( off the front with aluminum heads,intake RMS front end). So heres the question are 002/003 springs that came with this roller too light?. Do i need 456/457 springs or just try it and see. If there is no way the 022/003 springs will work i would rather which them now during the build.
 
Stock 62-65's weight is ruffly 3600 lbs as a street car. Remember to add your weight to your total. The variables differ with each car and equipment. When my 65 had a "B" block engine and full street trim with me in it the weight was at 3780 lbs. Our rule of thumb was aprox 200/300 lbs less when picking springs.I went with 3400 lbs. Works for me.

I'd sure try the 002/003 set. The set I patterned off mid '70's 002/003 using my stock '65 main leaf worked perfectly in my '65 Coronet 10.60 - 10.70 car 3450# w/me. Car left level w/4-6" air for about a car length. Working to get my Satellite to that point.
