50 seems quite good if oil temp is at normal operating temp. My service manul is at the shop so next time I'm out I'll look up the spec for minimum oil pressure on the LS1.
Some info is available in the owners manual:
"Oil pressure should be 20 to 80 psi (140 to 550 kPa).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still be
considered normal. It may vary with engine speed,
outside temperature and oil viscosity, but readings above
the shaded area show the normal operating range"

My real question, do I need to baby this until it gets up to temperature to keep from damaging it? Will it cause harm running it to say 3000 RPM and causing the pressure to rise?

I notice that when I start the car first thing and begin driving, my pressure is kind of high I think, starting at 40-50 but right before shifting, it creeps up to 60-80. Once the engine is warm, it seems to hang steady around 40-45 at a cruising speed.
