Nothing fancy, but doing a 69 C-scratch original CJ, making a hyd roller CJ stroker with some other goodies for a 69 CJ C-6 car
However, it had two #1 cam bearings in it, position 1 and 2. A little weird with the bleed groove in #2, but I heard Ford did the resize the day to save a block and had a #1 sized non-channelled bearing at the time. This engine has been rebuilt and the previous builder just used a second #1 bearing
I have a set of aftermarket block cam bearings and will break up a set to avoid a #1 slotted bearing in #2 for style points mostly, but I also have a single #1 coming that may not have the groove as well to avoid eating up another set. First one I have seen. Could have been a later machining correction or could have been done on the line as I have heard of it before. Either way, was funny to see the #1 cam bearing in there

The NOS 428 service block I ran for 19 yrs in the wagon had #2 cam bearing out of location from new. The first time we assembled it we found this little snafu. We bored #2 for a #1 and then soldered the groove shut. Every freshen up(about every 5 yrs) we replaced it. The block sits in the garage waiting on another project to go in someday.

When I built one of the first Genesis blocks they did not yet have cam bearings for them (I released the original 1268M set from F-M a few months later). I used five of the "number one" bearings with drillings as needed and left the slots in there. Worked fine for many years. That block is still out there somewhere...

I can't imagine that it would matter as you've seen too, a very small groove and in the #1 position, that path feeds the distributor and the plate groove without burning up a bearing and this would be more restricted than that in the #2 position.
I may do that, I have a few Durabond #1 singles, The other side of me still wants to break up a set for style points no-one will ever see LOL
