I'm doing an LS1 swap into a 71 LeMans and was looking at Summit's lowering springs while I have the suspension apart. Since the LS1 is much lighter than the original all iron engine, will the car sit nose high? Should I cut a coil?

I have these...http://www.summitracing.com/parts/be.../model/skylark

Although I have to admit I havent had the engine in the car and on the ground with them in. Worse case you just cut a coil up front. Thats not an option in the rear though. Keep in mind you might need adjustable upper control arms in the rear to keep your pinion angle happy. Not a big deal though...

i would cut first to fit, if you have to cut alot then order lweirng springs

After I did my Swap on my 71 Chevelle. I used Hotchkis (SBC 1 1/2+" drop) springs and B-Body spindles (another 1 1/2"+ drop), the combo should have lowered it 3-4 inch.. but once completed, the car was about stock height. I had to cut the Hotchkis spring a 1/2 coil to get it down to where it look right.

Just adding what I had to work with.

Just remember, cutting coil springs will lower the car but will also increase the spring rate and make it ride stiffer.

Yup.. cutting the top coil will increase the rate by about +10%....

But it's not too bad, but it handles well on the road and on the Auto-X. My 4x4 Van rides stiffer.. LOL..
