it looks like you got it as you want it now. also, it appears that your setup is like a M2, in regards to the engine placement directs almost the entire engine weight roughly at the center of the wheel. this was exactly why the M2 had 4, 6, and 8cylinder springs of differing rates. that is also why when the M2 setup is used in a prewar hot rod almost 100% of the time you will be using 4 or 6 cylinder springs even with a heavy big block, as the engine weight has been shifted behind the spindle center line, often by a large amount. as your new springs appear used, and you still need to install the front clip and fluids, if you had some idea how much those components weighed, you could get a couple of friends that weighed roughly the same weight to stand on the frame horns and get a pretty accurate idea how the car would sit at ride height. but i agree, i believe you will be real close to the stance you desire once those items are reinstalled. the car looks very nice by the way.
