I was just replying to the question. A 455 can't return oil over 4500rpm for any extended length of time without it pooling in the heads. The return line was the trick to getting oil back to the pan. My first experience with a 455 was in a Marlin jet boat I renovated many years ago. I ran it at 4800 for lengthy periods with out oil pressure loss. Scary thing. 85mph at 4800. I could shoot a rooster tail 80ft in the air.
