Well Done Damien :)

Dan

What would be the accepted "correct" height from ground to bottom of fender, with stock tires and rims for 1970 SS454. Any difference for 1971-72 SS454 . Thanks

If it helps Rick, the last few cars I've done I used Coil Spring Specialties and have been very happy with their coil springs and ride heights.

I have been using Hotchkis 2" and 3" drop springs to get a nice ride height. This Judge has a 2"drop spring.

Looks great

I would love to know what exact springs people are using to get them to sit correctly. As of late we have had nothing but trouble getting these cars to sit down where people like to see them. I have 4 cars in the shop and all 4 sit at this height. ALL have original assembly line springs in them on all 4 corners. Two of them still had the tags on them when they came in as well as original assembly line shocks but sit high. I have tried several different Moog springs and am now onto trying Eaton springs. We have also done all the math with the vendors to try and resolve it and have a TON of money in both labor and spring cost and have not been able to get them to sit right. Been doing this for 40 plus years and these last 4 cars are killing me.

I am the opposite. I have a 70 Elky,454 factory air. When I bought it, it sat way to low. Ordered Elgin springs, supposed for my application, barely raised it an 1 1/2. It is still to low for my taste, I like the front end to sit higher. Not a gasser look, but a little higher than the norm.
What are the springs and #'s you used to get the higher look?
First pic is with springs when I got it, second after Elgin installed. Has repro 15" wheels. It is now 27" from the ground to the wheel well lip.

A couple of questions...

Did the factory set ride height estimating passenger weight or just the completed car?

Does is matter if the springs are placed in the exact same location as they came out of?

Out of curiosity only, what do you consider 'accurate ride height'? I'm guessing there is some variation depending on how each car was equipped. Yes I know A/C cars received different springs but how much weight difference would there be in a heavily equipped car vs. a bare-bones version?
FWIW, I just measured my car. Something I found somewhat surprised me, and yet it's understandable. (I recently replaced the upper control arm bushings on the passenger side.) Measured at the axle, floor to bottom of the Wheel Opening Moulding, sitting on stock 50 year old springs and shocks, and on Repro F70-14 tires at 32 psi, here's what I found:
LF: 26 3/8"
LR: 25 1/4"

RF: 26 5/8"
RR: 25 1/2"

Just wondering how this compares.

Additional weight (lbs.) for added options: 1971 Chevelle SS 454:

AC = 106
P/S = 30
P/B = 11
PDB = 57
AM Radio = 9
Console (M) = 10
Console (A) = 17
4 speed = 5
TH400 = 48
Stereo Radio = 14

Mine is 26.5 inches floor to bottom of front wheel opening moulding with original springs, bushings and repo F60X15 bias ply on factory 15x7 rims at 29 psi on my 1971 SS454 El Camino M22 bench seat, no AC. Rear varies of course due to air shocks on El Camino, but I like a level stance. I think it sits okay, maybe slightly low due to age, always thought 27 inches might be what the as from factory height would have been, but who knows.

She is indeed a classic beaute. I have always been a fan of old cars.
