I know this question has been answered by forum members before. At the time I was planning to lowe using a 550#(F41) spring. Now, I plan to go back to stock or maybe a 460# and want about 1" lower. I can't remember if the forum recommended 1/2 coil or a full coil to lower 1". BTW, I'm switching from polyurethane bushings to rubber. I was plagued by the squeak. No squeak when assembling and installing. "Lots of squeak" under load. I'll wait for the "in-place" greasable units that are made for hot rods.
Thanks, 73C3

I cut half a coil off my original FE7 front springs,and that gave me 3/4"-1" drop. But check on the 550's,as you may obtain the same results without cutting,if I recall correctly...

I used 550's and cut them 1/2 coil each. Ride height in front was 29" with the OEM springs, and now it is 27.5

The 550lbs springs are great with the Bilstein HD shocks. I did not cut these - see below:

I didn't have that kinda luck on Yvonnes 1973 small block. I cut off 1/2 a coil and only got 3/8" lowering - and that was measured well after a settling-in period. And I triple checked that the coil was seating properly in the top pocket.

If I had to do it all over again, I would of cut-off one complete turn.

I'm at 26.5" (245-60-15's) but I did it to original coils back in 1982....still have them and no measurement change...
Looks like your front end package worked out good...followed your posts on that...

Assume you are talking of stock 15" wheels and all.....guess that could happen...at the time,I was running 255-60-15's.....on 245-60-15's now...

I would only cut either a 1/2 coil or 1/4 until you reached your desired height. Taking a full coil may lower the car more than you desired. I've taken a 1 1/4 qtr off mine with 17" wheels. My car is pretty low and I wouldn't recommend it for a daily driver. Rod

I agree, it's a little lower than the average C3

I just posted info on this, I put 460's in my 73, 350 sb with mods (aluminum heads, manifold, etc.) My front end was lightened about 90-100lbs., the coils measured 16 1/2" outside measurement with a cloth tape. First time I cut 9" off, tried it for a few days, was at 27 9/16", cut another 4" off ended up with 26 15/16" just right for my 245/6015 tires. Again the cutting depends on the weight/options/ mods you have done to the front end...

YA ,read a few posts then ask

my 71 small block with stock springs was @ 28" on the left and 28 1/4" on the right. I cut 1/2 coil from the top of the left and 1/2 coil + 1.5" from the right. Luckily...they both came out @ 26.5" on both sides. Lucky I guess on the first shot

Seems like you assumed the frame was not level - one option is that only the body was not exacktly level even the frame was...
