On a mostly street driven 302 that won't see over 6,300 rpm?

Cross drilled mains are mainly used on motors producing loads of hp. I think your 2-4 bolt mains should be fine.

I mean crossdrilling the oil passages in the crank so that the rods have full oil pressure at all times with only a 1/2 groove main bearing. Is that what you are talking about? I am not talking about the main caps. Thanks for the help, Brandon.

I wouldnt do it.....it weakens the crank.


Heck, I dont know of anyone crossdrilling Cleveland cranks, even with their "inferior oiling"

Mr. Smokey "Thrash-the-Nascar-Engine-to-Death-on-the-Dyno-a-couple-of-hundred-times" Yunick thought crossdrilling the crank to be pretty much a waste of time. I've yet to hear of anyone proving otherwise. I wouldn't worry about it.
