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.
