I was going to take a couple of quick pictures of one of my old tubed blocks that is headed for the scrap pile but really you can’t see much. We had a couple of real good posts on this subject several months ago that you should be able to find. It involves drilling the block oil passage app 10 inches from the front and back of the block and tubing it to prevent oil from gushing out around the lifter bodies. I will take detailed pictures when I do my sons but he hasn’t been in the shop mood and I’m not pulling his engine for him.
