The core engine I am working with, came out of an '06 truck...it had an adapter that pointed the filter toward the front. I also feel that the filter area may be of some concern contributing to the afore mentioned bearing problems...LOTS of small passages and restrictive angles involved in the castings. I am eliminating these with an external oil pump system that will feed into the hole right above the filter..with some minor mods to the original feed hole in the block, and a remote filter set-up.
