"Hintenachse" from 730i into 750i

[schnitzer]

I have thought for a long time to put the 730i 6-cyl "hintenachse" into my 750i. What do you guys think of that? Have anyone test that before? 750i has 3.15 original and 730i 3.64 I think. The car will be faster to the topspeed.
If you put a 730i "hintenachse" into a 750i, then to make a normal 750i with 3.15 go like the one which have 3.64 you have to give the car 48 bhp.

What "hintenachse" has the B12 5,0? I have heard 3.45, the same as 735i E32? Is that correct?
