Coil spring suspension question on a D100

I have front coil spring suspension on my '74 D100, I was wondering if I took the set of /6 springs and replaced the original 360 2bbl springs with them, would my front end sit lower or would it change nothing at all? My buddy has a foxbody and changed his rear coil springs to the 4 cyl coil springs and his rear end dropped a little bit and gained him a little more traction. I am just looking to get my front end a lil lower with whats on hand really.

Any input is appreciated :cheers:
