I dont know the details of the specific application for this build, but...... Fwiw, about 25 years ago I was building oval track 318's and 360's(multiple track and series championships) that were running a little over 7000rpm(solid lifter cams) at the better tracks....... And those motors received no oil system modifications at all.
Proper clearances and quality machining...... No oil related failures.

I used the Canton oval track pan and a std volume pump with a spring set up for about 75psi pressure at high rpm.
