Coupla things.. Tom, can you take a picture, or scan or give us an idea of exactly where you got those .63 (5/8") numbers? That would make me feel a little better.
Also, if it was your engine everyone, would you try to push that pin in? Or try to take it out? Or leave it alone? I am on the fence here. The engine was thoroughly gone over and cleaned really well inside and out. Since its an oil galley part, maybe its lubricated enough to move? How hard do I hit it?
Below is todays photos of this engine. This is not its first rodeo because they had to bore it to 40 over. I will be writing about this fiasco, so added the number pics too.
Tim, where did you go to confirm the numbers on my 1964 261 motor? Ya know, leave it to me to have the one in a gazillion motor!

Good news is, as it stands, the motor runs nice, good pressure (right at 30), good flow. The only problem is my full flow filter will last forever and the engine oil won't get the filtering benefit.
