F350 factory rear spring blocks

[johnsps250]

I know this has been answered in the past but I have done quite a few searches on it and I haven't been able to find an answer.

Does anyone know how much lift it will give you to use f350 rear blocks in the rear of an f250 ? Also, I know it is recomended to replace the u-bolts whenever they are removed. Do you need longer custom u-bolts, or do you just order the u-bolts for an f350 as well.

Thanks
John

Here is a link to ford's site with the height specs. It shows the F250 at 79.1 and the F350 SRW at 80.8. So about 1.7" if both springs are new and not sagging. >> Ford Vehicles: Super Duty - Specifications

Thanks for the reply,
I am actually more interested in the actual measurments of the blocks, I think that would give me a better idea of the stance of my truck when I am done.

Is there anyone that's done this swap that can give me any info on their results?
