What is a good combo for turning high rpm?

OK cool man. There is an oil mod thread here by Guitar Jones IIRC that ddress the high rpm oiling issues of the SBM engine. It is a simple thing to address.

It was a simple drill and tap of the oil galleys within the valley with one side feeding the other with a bent tube crossing over sides.
the oil pump mods were a simple grinder chore smoothing out bends and transitions.

Off the side of the block can some drill and tapping for lines to run oil to a cooler.

I'm going to look into this type of racing. I think it really cool but really have no idea of how things are done drivetrain wise.
