If it's an electrical gauge, it's possible the sending unit in bad or not grounding properly. One reason I've always been leery of electrical temp and pressure gauges. If it's a mechanical gauge from the factory-type gauge option, connecting another mechanical gauge inline will let you know the true pressure. These mechanical dash gauges can be replaced fairly easily if the gauge is at fault.

It's the gage in the dash cluster that's pegging the needle so I can't switch it. I guess I can try a different gage to see what pressure it really is. Not sure I want to pull the engine. Thanks again.

If you can't do it, then worst case you get a cherry picker and raise or pull the engine. I think it is possible, but I have never tried it in a Chevelle. I think I was able to do it in my '66 Corvette, but that is a much different car. You also should decide if you really need to go to the trouble of swapping out the pump (or spring) to lower the pressure. While you may not need it, and it might be costing you fractional horsepower, it will likely be a lot faster, easier, and cheaper to sawp to a high pressure gauge, as Dale mentioned.

I need to change the high volume oil pump. It's sending the needle off the gage. Thanks
