Steady oil pressure?

[Tab Julius <tab@penworks.com>]

I have a 78B that still needs to get tuned, in terms of the carb (as soon 
as I find someone nearby that does Zenith-Stroms).

I've seen a number of posts over time referring to oil pressure being X 
during idle, and much higher, Y, during driving.  As far as I can tell, my 
oil pressure seems to be a steady 55-ish all the time, idle or no idle.  Is 
this normal on a 78B, or is something wrong?  (if so, what?)

TIA,
