t is possible that a 4bc1 Isuzu engine may fit in a Bedford Elf truck, but it would depend on various factors such as the specific model and year of the truck and engine, and any modifications that may be required to make the engine fit properly. It is recommended to consult with a qualified mechanic or expert in Isuzu engines and Bedford trucks to determine if this engine is a compatible and appropriate option for your specific vehicle.
