Engine.......Bore..................Stroke ..............Rod
4.8.......3.78" (96mm).......3.27" (83mm)........?
5.3.......3.8 " (96mm)........3.62" (92mm)........?

6.0.......4.0" (101mm).......3.62" (92mm).......6.098
Anyone no where to find detailed engine specs on the LS? link?
Looking for rod lengths ?
Piston details, such as wrist pin location, are they all in the same location?
