Dart shp block

The slots in the lifter valley were sealed except for part of the back one. The problem is that with the slots sealed and the webbing cast into the block to make the cam tunnel stronger there was no way to get the oil back to the pan from the front of the motor. Some holes drilled in strategic places should fix this. The webbing was acting like dams in the lifter valley.

I suppose you're trying to keep oil from going down past the cam onto the crank and rods. Not sure there is any gain there, there are tons of fast big blocks with the lifter valley drains wide open.
