I´m not an authorative source, but I believe the ´94 and ´95 models had a
de-tuned cam, and the more restrictive exhaust, because they had to get
closer to passenger car emissions. The ´96 regained all the lost
horsepower, and has a hotter cam, because the OBDII computer does a better
job of regulating fuel supply.

Now what I think would be interesting, would be to put a ´96 or later spec
engine in a ´92-´93 truck (I´ll volunteer mine) with a ´93 computer and the
less restrictive exhaust.

Torque is under-appreciated. Especially when you have the mass of a Dakota
to move. And these are TRUCKS we´re talking about!
