You didn't say what engine you have, but that sounds like normal for a stock gen 1 chevy small block, and even with a relatively well built (hot rodded) one, it is still normal. A lot depends on the clearances built into the engine at the time it was built, and the type of pump and oiling system it is running. For a stocker, it's just fine; I have never had one that was different in stock or near stock form, and never grenaded one, even drag racing. This subject sometimes gets a lot of play here, and there are situations when one might want, or need more pressure, or volume, but for a stock engine with normal clearances, yours is doing what is should.
