I am fitting new liners in old C barrels (muffs) for a 6xxx Shadow and decided to study the oil hole placement. I have a B series apart as well and the oil hole placement is much different. I go back and read KTB, Richardson, and other references...........and I find myself unhappy that there is not a dimensional sheet to study to establish ring position vs oil hole...............and a 50 degree axis reference for the 3/32 hole for later cylinders.....and a "groove" referenced which is so wide as to go beyond "groove" as I call it.
Also 1" x 3/32" wide woodruff key seat cutter, use of it not making any sense to me, as the flat cut is 1/2 wide.
There is no reference as to where to clock position this hole, there is no reference as to checking the cases to allow for your best hole position.
I would like some help with a dimensional drawing showing ring vs oil hole.
Should all the early Bs convert to later liners with lower oil holes due to excessive B oiling?
What is the 50 deg hole advice?
Thanks, Craig
