Installed new suspension/major problem

[mprat]

Awhile back while I had my frame out I installed all new upper and lower A arms, tube ones. Everything new including big block springs. I spared no expense. Now after I dropped the engine in tonight a 454, the springs have the travel all the way up. If you step on the front of the frame and jump on it just a little it will slam against the upper a arm, its so tight I cannot even get the upper bumper in. Two of us standing on the front of the frame with a combined weight of around 475 pounds still will just lower it down about an inch. What in the heck is wrong here. I hate to think I have to take the springs out and cut a ring off. I just do not understand what I did wrong.. any help would be appreciated.....
