YR, maybe I'm missing something about the timing. My magnum block, with bearing installed, plumbs oil to the crank at the 12 o'clock position. The main oil gallery going towards the main bearing is offset at 11:00 or whatever it may be, but is corrected by the port hole in the bearing and "times" it to 12:00.
If the crank is spinning 7500, sure the total time of the crank hole passing the bearing is shorter, but the frequency of it passing by is more.
