It does seem high in the front. It is also a tad low in the rear. It looks lower at the rear in the first photo than the second.

Here are the options as I see them.

1) Cut the V8 springs by 1/4 coil at a time and install and drive until you get the stance you want. You will need an alignment after this is done.

2) Do the "Shelby Mod" to lower your upper control arm pivot by 1". This will drop the front end slightly and improve handling and is a free mod except for the required alignment.

3) Buy a set of L6 springs and try them.

You should also be replacing the rear springs if they are original. They are over 50 years old and certainly need some attention. If fact, you should probably start at the rear. Get that height where it should be and then adjust the front for a very slight nose down stance.
