More leaf spring questions

So I just got the front of my truck weighed. Driver's side 1,500 lbs, passenger side 1,300 lbs. I figure the Cummins we put in has compressed the existing springs at least 1" lower than the 390 and the weight on the driver's side has compressed just that side an additonal 1/2.

Anybody with any input on new springs to brings this highboy back to ride height and level would be appreciated.

Also, the cab is leaning an additional 1" to the driver's side. I just replaced all the cab mounts and it fixed the problem a little, but I am trying to figure out where the rest of the lean is coming from. Any idea?

Go to your local spring shop. Have them either re-arch or replace the springs. If they're good, they'll know exactly what you need.

If you centered the engine in the frame, there's your problem. It should be offset a couple inches towards the passenger side.
