* Engines: The most common engines were likely a 318 cubic inch (5.2L) V8, a 360 cubic inch (5.9L) V8, and possibly a six-cylinder engine (though less common in a D250). The specific output (horsepower and torque) would vary slightly depending on the year's specifications.
* Transmissions: These would likely have been a three-speed automatic transmission (likely a TorqueFlite), or a four-speed manual transmission.
To know *exactly* what's in a *specific* 1985 Dodge D250, you would need to:
* Check the Vehicle Identification Number (VIN): The VIN contains coded information that reveals the engine, transmission, and other factory options. A VIN decoder website or a Dodge dealership could help decipher this information.
* Examine the engine bay: Looking at the engine itself will reveal the displacement and often a casting number for more precise identification. The transmission identification is usually visible on the transmission's case.
* Look at the paperwork: If you have any original purchase documentation or maintenance records, that would provide definitive information about the original specifications.
Without more specific information about the truck in question, it's impossible to say for certain.
