the 3.7 liter should be rated at 165, 170, 185, or 190 depending on what year model you have. The 2.5 was rated at 120, the 3.0 was rated at 115( late model, measured at the prop) 130, and 140 depending on what year. The 3.0 LX was rated at 135( late model rated at prop). All these engines are rated to turn between 4400 and 4800 at WOT, light load. If your engine has a heat exchanger, closed cooling system, and if the instake manifold is on the oposite side of the exhaust, you have the 3.7. A lot of people give this engine a bad rep, I have had good luck with them. IF the carb is mounted on the exhaust manifold, its the 2.5 or 3.0, its a good engine but its only going to do so much. What engine do you have?
