* Multiple Engine Options: GMC trucks from that era offered a variety of engine choices. There were gasoline and diesel options, and horsepower varied greatly.
* Specific Fire Truck Modifications: Fire truck manufacturers often modified standard truck chassis, including engine choices, to meet their needs. This means the engine in a 1954 GMC 630 fire truck might not be the same as a standard GMC truck from that year.
* Individual Truck Variations: Even if a specific engine was common, the exact engine size would depend on the individual truck's build.
To find the information you're looking for, you'll need to do some research:
1. VIN Number: The Vehicle Identification Number (VIN) would be the best way to track down the exact engine specifications.

* Fire Truck Historical Societies: Look for groups specializing in fire truck history.
3. Fire Department Records: If the truck belonged to a specific fire department, they may have records of the engine and other specifications.
4. Fire Truck Parts Suppliers: Contact companies specializing in vintage fire truck parts, as they might have information based on common configurations.
