1970 chevelle LS6 and L78 rear springs

[P.J.]

does anyone know what the factory height of the 70 chevelle
LS6 and the L78 is from the ground to the wheel openning mouldings front and back? The assembly manual shows 2 different part numbers for the front and rear springs was the L34 a different height than the L78 and ls6? The reason I am wondering is that I used the origional springs in my resto and when finnished the car sits lower in the back by 2 inches than the front. I know that over the years the constant pounding of the big block on the rear end took its toll on the spring height. I want to get it right
Please help

Didn't know Rick got a new job ! Heh Heh

It actually should sit lower in the rear,then the front, originally.
Any idea what Part numbers are on the springs you used,or even what two Letter suffix tag they had?
What are your front & rear measurements at now?
Starting in 1969,they selected springs diiferently,using a Computerized selection process.It wasn't so much about an engine being an L34-L78-LS5-LS6,2DR or 4DR,or even convertible,but more about what options the vehicle was determined to be built with,Power steering,power brakes,AM/FM radio,Transmission,Door locks,A/C,etc.
If you have a buildsheet what is the sufix call out in those respective spring boxes #13 & #14?
If they are GB-GC-OO-OQ,it originally used Front #3960665,& Rear #3960652.
The Assembly manual only shows Standard Base Spring numbers,nothing more specific.

Your assembly manual has a chart that lists ride height. Remember, none of the Chevys were jacked up from the factory - they all look low in back.

I have 24" 1/2 rear height from the floor to the wheel well moulding and 27" 1/2 front. I used the origional springs F41 suspension. I know that the chevelles did sit higher in the front than the back however did they sit 3 inches lower in the back than the front.? The assembly manual shows a floor to body height in the front of 9.70" with an f70 14 tire and in the back 9.46" curb height.Mine measures 9.5 " in the back and 10.5" in the front.In order to figure out
if that is normal for the chevelle as far as the car
sits is concerned one needs to know what the factory
dementions for the f41 rear springs are.By measuring my old springs I could then determine whow much they have shrunk.My front spring code is GB and the rear spring OO OO
I tried to post a pic and could not.

Has the car seen any road use since the spring installation? It's common for the front end to settle down quite a bit after a few bumps and bounces allow the coils to take set. Run it over a few speed bumps and get 30-40 miles on it, then check again, I think you'll find it sits closer to level. JMO.

yes I will try to get some milage on it to see if it makea a diff. However if thats the way they sat so be it, MR 70
gave me the spring part number for the back I checked with
Delco and they told me that gm still has some I will try to order 2 to see if that changes the ride hight.
I would realy like to post some pics of the car but for some reason I cant post I am using phoshop 7 then saving for
web and then reducing the pic to 12.5% the smallest size and it still wont accept it.
can someone help

Send them to me via my email via my username and I can resize them &amp; post them for you...Photoshop can be a pain to learn.

<font color="blue">Make sure when your done with photoshop, the pic is saved as a 'jpeg' or 'gif'.
I've had that problem also. http://www.yenko.net/ubbthreads/images/graemlins/tongue.gif </font>

In the 70 Chevy overhaul manual curb height is measured at the front and rear rocker panel.10 inches is the average measurement.Ride height is measured between the top of rear axle tube to bottom of frame rail,not to the snubber.They call for 5 inches at that point.

[Fhakya]

This should do it. When saving in Photoshop, it should ask you what "quality" you want to save it in and will show (in very small font near the bottom of the window) the file size.
For posting here it just needs to be under 100K if that helps in the future. I simply went to File, Save as, I renamed it and selected low quality (3) which brought it down to 66K.

Car looks good to me! I love that color! http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

Peter:

Car looks fine. According to your dimensions, rear is right on and front is high. My experience with new restos is that the front is a little high until it settles. I have a 12k mile 70 SS (untouched) that looks like a lowrider compared to my fresh LS6!
Love that frost green!

Looks great! http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif Dave, I think that's actually code 45 "Green Mist."

[P.J.]

and nut was the origional as this L78 car has been owned by me for about 24 years and it was time to restore it.

Green Mist, of course....... I slipped into 69 Camaro mode....

In the 70's, it was very uncool to have a green car. It has taken many years for me to get over that, but boy, am I over it.

When I first purchased the car 24 years ago and i found the origional build sheets in the back seat and realized that it was mist green I almost threw up. About 2 years ago I was at a car show in moncton New brunswick Canada and I saw a chevelle delux 300 with new mist green paint Well I
was more than impressed to say the least.
thanks for your responce
