4.0 in a DII

That's why I sold my DI and bought a Honda. Having two rovers just wasn't reliable enough, especially when they both were broken at the same time

not worried about the reliability of it!!! I just know a guy that happens to have a DI that is wrecked but still runs. I could pick up the whole truck for 600 bucks... it would help me if I could use the drive line as a spare. also a lot cheaper then buying a junkyard one!! If i could even find one around here that did not require me selling one or two of my appendages!!!!!!!!

Yes the 4.0 and 4.6 are the exact same block and heads, the only difference is the guts.
Different stroke, so different crank and cam.
I am not sure if they increase the stroke with the crank or with the connecting rods.
But either way, yes, you can buy a BOSCH 4.0 block and rebuild it with 4.6 parts and have a 4.6.
HOWEVER without the 4.6 computer you have done nothing other than rebuild a 4.0.
It is very common to install a used DII 4.0 into a '03-'04 when the engine blows up because it is a direct drop in.
Also keep in mind that you can buy a P-38 4.6 from a wrecked Range Rover or a Range Rover that is in very vary bad shape.
The P-38 also uses the BOSCH system.
