Thanks Theo:
You have another engine producing similar pressures to mine. However I never
see 50, but I do see 25 at idle. Brand new crank, rods, inserts, and oil
pump. Now just under 400 miles since refresh.
I suspect these are more normal pressures than I had been led to believe.
But there are many Tiger blocks out there producing some truly impressive
pressure numbers.
Thanks for your input.

Subject: RE: [Tigers] Oil Pressure
I haven't tried a modern oil pressure gauge on my engine, but it reads about
45-50 psi cold, 25 psi hot at idle . The pressure does come up as you rev
the engine, but it rarely goes above 50 PSI on the gauge. This is a 120,000
mile 5.0 with worn bearings...
Custom block adapter (similar internal orifices to the Canton and Dale's
adapters), -10AN lines to a left-headlight mounted filter with a 90 degree
tubing bend on each line.
There is no flow through the gauge line, so there is no pressure drop across
the gauge line. The only thing that is influenced by the size of the gauge
line is how quickly the gauge might respond.
