What are these marking?
I have a couple of questions about the 225 from my 63 Dart;
I have read that assembly plants would put various markings on engines as they went down the line but does anyone have any idea what these may mean? This is what was underneath the grime.
The second question is about the spark plugs. I've read conflicting thoughts on whether or not I should remove the sealing ring at the base of the plug so it reaches deeper into the chamber. I'm using RN14YC plugs with 3/4 length thread. The motor is bone stock & never been apart. Thanks!
