If you are sure you are going to pull the pan, you can always jack up the car and try it to see how close you come to getting it off. 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
