Ralph, my apologies for ignorance. Does that mean the factory drilled out
the center main oil hole, or does that mean I should drill out the center
main oil hole. Where do I find this and what is the best way of drilling it

there a little while) Thanks,
Patrick

To quote from Kas Kasner's Competition Preparation Manual " The oil feed
holes to the end main bearings are kept stock, but since the center main
oil
hole feeds two rods, it is drilled out to 5/16"
