LS7 Connecting Rod Length? Does anyone know what the length of the LS7's titanium connecting rods are? I'm assuming the LS7 block has a standard SBC deck height. One would think that the rod length is at *least* equal to that of the LS1/6, and due to the LS7 needing to rev so high with such a long stroke, they would be even longer.
Does anyone have any hard facts regarding this?

Actually, GenIII does have the same dimensions. Actually, the LS1/6 (all Gen III blocks) have 'the same dimensions' with regard to what classifies them as a 'small block'.
The three basic measurements that, according to GM, classify a cylinder case as a 'Small Block' are bore center-to-center distance, cylinder case deck height, and lifter bore diameter.
All Gen 1, 2, 3, and 4 small blocks share these 3 dimensions:
4.4in Bore Center-to-center
9.240in +/- 0.003in Cylinder Case Deck Height (measured from crankshaft centerline to flush top surface of cylinder bank)
0.843-0.844in Lifter Bore Diameter
6.098in would be identical rod length to that of an LS1/6 so I could see that. Hopefully they are 6.125in. Again, anyone know for sure?
