Since you mention "after block #R40000" [NOTE: You left off a zero], I'm
guessing you're talking R16. According to The Datsun Roadster Book (which
you should have), the block threads are SAE up through #R40000, then metric
after that. I'm guessing there may be an exception or three to that rule.
Always measure to be sure.
However, when we're talking bearings, STANDARD does not mean SAE, but the
standard or stock dimension. From there you go oversize or undersize,
usually in 0.010-inch (or 25mm) increments. You'll see this in the parts
manual. The downloadable PDF version is kinda hard to read, but easy in The
Datsun Roadster Book.
The bearing caps may also have the size stamped on the back either in inches
or millimeters.

More info needed I think:
According to my machinist I need standard bearings.
What I want to be sure of is getting the correct type: standard or metric.
thanks!

here's a dumb one from me to you all:
Crank and rod bearings come in standard and metric, correct?
How do I determine if I have a metric block? is it simply a matter checking
the block number and making sure it is after block #R4000? Or is there more
to it than that?
Thanks!
tim
