That one's been for sale on there for at least the last six months. It keeps changing a little each time. Started out as bare cases for sale.

I thought drilling rods would be counterproductive. Was this standard? I thought that engineering practice went out with the Arc!

All original WR rods as well as early KR rods are factory drilled. It still reduced reciprocating mass and was considered good practice for a long time. I have had lots of stock WL rods that were drilled by home tuners over the years. Some very poorly! :shock:

If the entrance and exit shoulders of each hole have a small radius on the corners, along with a nice finish, I would think the rods may even be strengthened as a result of the modification, as well as lightened.
