Nice article , I just read your "How To" about front of block. I am building a 1990 model year 360 and I found on the old front gallery plugs one has a hole in it and it has a different cam plate than what you have in your article. So I will add my two cents. By the shape in my plate I suspect the hole flows pressured oil against plate that will now drip along plate and tab to drip on chain & gear. Here are pictures. Feel free to add them to your article. Cheers !!
