Not that much, maybe 6000rpm at 400+hp, but I've had bottom end oiling problems on B/RB mild builds before, particularly with oil starved rod bearings. I'd feel better if I could just get a bit more oil down there. I've already drilled the 2 thru 5 passages to the galley to 9/32's from the main saddles but got confused when I got to #1 and thought I'd ask.



With all due respect....

If you had problems at that level, it had nothing to do with the block. I have built legions of B/RB's with way more power than that and have had no failures that you refer to. The bottom ends on these engines are particularly good, especially when compared to some of the other offerings from Detroit during the same time period.
