A year or two ago, I read an article on the ORC site by Shawn Spickler about installing an auxiliary oiling tube that sat in the intake valley and was centered above the camshaft, which helped deliver more oil onto the cam lobes. Before this article, I had never seen or heard of anyone needing extra oiling in this area, and I didn't realize it was even considered a problem with the big block Chevy oiling system. Of course, most of what I read concerning big blocks was in street machines and road racing, not rock crawling stuff. I'm in the planning stages of a 402bbc and I'm wondering if this is a necessity, or a luxury I can do without. Does the BBC need extra oiling help in this area? What are your experiences?
