oiling system changes are pretty much required at this level, and i have snapped a few pics of some things that might slip thru the cracks, but really should be addressed.
the adapter that bolts to the bottom of the block for the remote mounted oil filter is a bottleneck in the system. it really needs to be completely redesigned, but we have done the best we could modifying the stocker to remove the restrictions. if you look down into the slot on the top, and the hole drilled into the side of this adapter, you will see that very little crossectional area for flow between the vertical entry and horizontal entry exist. its a good idea to use a small carbide cutter on a long shaft, or some small chainsaw type files to remove enough material and radius the turn so that flow isnt so restricted. tried taking some pics of it, but its extreemly hard to port way down in this small hole, and even harder to photograph what we did. (you are looking in the hole where the bright light is focused)
also dont make the mistake of installing this part without the correct gasket pack from GM. (third picture) not only is there a filter type rubber ring gasket around the outside edge, but there is a gasket that goes on top that keeps oil from bypassing the remote filter.
