Wow...sounds pretty cool....dropped it 10"...got any pics?....sounds like it is on the ground...mine sits normal and I only have 5 1/2" under the headers...9" to the frame by the front of drivers door.....if you got a "tube" front end..can I assume it has coilovers?....then you would simply get a stiffer...more lbs (springs are rated by lbs of force it takes to compress it) spring to compensate for the "big 440"...with the all aluminium Hemis, I like the 400lb spring...for the cast block Hemi w/aluminium heads, I like the 450lb spring......hope that helps somewhat....still like to see a picture just so I can get a handle on what you are doing
