Is there anything I should be looking at doing at 150,000

You might want to consider selling it or rebuilding the motor. It probably won't take a lot of ppunding. I had that same problem with a 87 5.0 w/ chrome Cobra R's. The car was real clean and it sounded good but the motor was tired and smoking badly up steep inclines. I sold it for 5K and saved up. It's better off to start fresh.
