The quality of the block seems excellent, I just don't know why Dart didn't do this to start with. Their little M block has them.

Greg, are you talking about those two big holes behind the timing cover? I've never put those in. The Dart blocks I've used have the returns like a big block, over the camshaft. I'm not sure those two behind the timing cover even do anything, except maybe after you start to slow down. I have not done one for Stock, but I have done some for regular bracket cars. I have not had oil return problems.
