>I've just completed assembly of the chassis / drive train of my 1957 TR3.
Yesterday I turn the engine around for the first time using the starter
(no ignition yet) and my question is: Am I right to worry not being abel
to get oilpressure readings during this short, slow RPM turning?
Is there anything I could do to ensure oil is transfered through the
system?

You should see oil pressure when turning the engine on the starter but
since this is a fresh rebuild it may take quite some time to prime the
pump. If you have the spark plugs removed the starter will turn the engine
more quickly with less load on the starter so you can turn it for longer
periods than if the plugs were installed.
Since this is a fresh rebuild did you pack the oil pump with some grease?
The pump depends on oil filling the clearances and without it (if the pump
was dry) air will blead pass these clearances and it will not pump well at
all. Packing it with grease (both petroleum jelly of the special engine
assembly grease are good choices) will close off the clearances within the
pump and it will prime more readily. Without oil or grease it may take
several minutes of cranking before you get pressure.
I highly recommend that you verify oil presssure before you attmpt to start
the engine.
