| Essentially you have the "T" portion indicated...I just wanted members here to know that the main oil galley from each main supports a set of rods etc etc. I agree completely on the V8 difference however most of the performance oiling details in the new crankshafts made by GM/Callies/etc etc have a new foot print so to speak on how the oil is delivered from what I remember. Oiling angle and so forth. Its odd that even Cummins has a high speed oil system to feed the bearings yet its max RPM is only to said like 6000. Most "cross drilled" low speed systems are designed to work in low rpm/load operations. None of what I've seen in the racing arena or any other forms of racing do they use a cross drilled rod journal. Its always a high speed configuration. The high speed oil system I speak of is allowing only exit point of oil to exit under any centripetal force or pressure backing. This ensures a constant laminate of oil is being supplied to the bearing surface at any time not allowing the "pin wheeling" to occur under high load/rpm conditions. This ensures the area of critical surface is sustained under those high loads. Ensuring that oil is always present no matter what range of operation the assembly is going through. As oil is continuously being fed, oil starts to move outwards in a more gradual state rather than being forced out not allowing it to lubricate properly. Enabling the oiling to function as it should under those loads is very black/white in terms of survivability. Again this is what I've found and worked on in the past and what has worked on numerous other engines I've worked on/built/tested. Makes no difference if its an import or not...all these engines are the same in principle
