I'm running an NA 427 620/560 to the crank and my KRC aluminum PS pump has treated me well so far since 2002. My trans is spec'd for Royal Purple by the builder and I change fluids after every track day and the oil still looks good. Trans in car since 2006. No cooler for rear diff either and car is used strictly for time trials on road courses. Same Eaton carrier since 2004.
This is why I asked the question.
