My truck's engine was originally rated at 235 HP and 295 ft-lbf of torque. What with all I did to it, I figure it's closer to 265 HP and 330 ft-lbf of torque. The dyno sheets I've seen so far suggest that torque output is more-or-less constant up to about 2400 RPM, where it rises to a "sweet spot" at around 3400 RPM. Still, it ought to be torquey enough, I figure.



Gear Vendors actually lists ratings for various Dodge truck transmissions, even those with factory overdrives. It's a promising step forward.

That dyno is from another Dodge Dakota owner - he's showing the results of his fuel rail cooling modification which helps ensure that the fuel temperature to each fuel injector remains constant. His modification was the inspiration for my own fuel rail modification that evenly splits fuel across both banks of my engine.
