Are you delusional? 20 HP difference in today's engines is nothing in a 3,500 lb car. The 20 HP difference between a 3.1 and 3.8 is at PEAK horsepower RPM, not at 2,000 crusing RPM. Stop with all this nonsense about the HUGH differences in a NA 3.8 versus a 3.1-It's not that big. In fact it is VERy small!
