You can buy a cheap gauge and thread it into the fitting at the block where the factory gauge is connected, or into the Tee fitting where the oil filter is (if you've got one). I bought a gauge at FLAPS for $6. It only reads to 50 psi, and that's fine.
Have you run the engine with the rocker cover off to see the oil? - Just curious, not being a jerk, as sometimes the distributer doesn't drop down enough to engage the oil pump. (Ask me how I know this!)
On my 235, I get 30 psi at startup idle, and then when the engine is warm, about 5 psi at idle, and 25-30 at speed (40mph). The pressure varies a bit with the outside temp.
