I had knocking in my engine.Turns out the piston bearings on the crank shaft were bad. Still some knocking.?

Question

My engine is a GM 3800 series II Before i replaced the bearings, the engine had a loud clanking/knocking sound. I replaced the bearings, changed the oil. There's no knocking when i start the engine However, the knocking isnt completely gone. I hear the knocking when i try to accelerate. The other thing i noticed, is my oil pressure gauge goes almost to the red zone, like its losing oil pressure. The other thing i noticed about my other gauges , is that they all seem to get really low, especially when i come to stop. Any suggestions? I love my bonneville and i dont want to get rid of it, but my last resort s to put her out to pasture

as far as the main bearing goes, is it worth even getting it repaired?I dont want to start spending more money than the car is worth. I love my car but im not rich either.
