Reason I ask is, not having them line up is not going to effect the mains. It will effect the rods at high RPM.
Its a old Whitmore trick he told me.
I have always done this and never had a rod or main bearing issue. Ran a 60lb pump in a 455 for years.
Lots of folks run 10-30 with 60lb pumps and do not have problems.

Not sure what you mean line up oil in tabs?
Runing a race ingine with .0025 rod clearance and .0032 mains, 60lbs pump
and comventional 10w30 oil doesn't give enough cusion for the bearings
That was the first thing my machinest ask is what WT oil was I using. I here people saying they run lighter
oils all the time but there not racing there motors like this one see's The main's are clevite rod's are king.
