Ok now don't quote me, but from what I understand, the m52 and m54 are basically the same block. Considering that the s54 block can be bored out to 3.5 liters, and it's based on the m54 block, I can see that being possible, but that'd be a lot of things to change, even to reach 375hp. That's a huge leap. And I'm sure it has built internals, again, don't quote me, but I am pretty sure the m54 wouldn't be able to handle that without being built, at least if it wasn't built the life would be quite short. So using that, I'd guess it's fully built, bored, sleeved, brand new m52
