Cross Drilled for better rod oil supply on #2/#5 rod journals. Yes, that is the theory. The pros have said this may not be needed for street driven cars. Based that my crank had a spun bearing I decided to opt for it while the crank was out. The rest of the engine was beefed up on so it made sense.
