I know this question is a bit left field, but, I'll ask anyways.
- Because the Bore and stroke are very close to that of the LS1, would it be possible to use some of the internals of the LS1 in the VK56. Let me explain...
The VK56 bore/stroke/rod length is 3.9"/3.6"/6.0826"
The LS1 bore/stroke/rod length is 3.898"/3.622"/6.098
Yes, I am assuming you would have some machining involved, but because bore spacing is essentially identical, the crank should be very close in journal width, and you would need to machine the journal diameter (if all goes well, I'll have both engines in my garage, I already have an LS3 that's going in a SL-C, but might get a VK56 for close to nothing, but won't be until late this year before I'll get a chance to tear into them both.
The reason for this,, you could build the bottom end quite cheap if you did it this way, because LSx engine parts (even the forged ones) can be had for pretty cheap.
On the top end, depending if you have a DE or VD, not sure if other parts would swap out with other engines (valve springs, retainers, ect),
