Gas Land Cruiser engines are manufactured by Toyota.
The F and 2F engines were also used in Toyota Forklifts.
The F engine is supposed to be based on the Chevy 225 I-6 "Cast Iron Wonder" and some of the bottom end along with the water pump and several other components are supposed to be interchangeable.
The main differences between the F and the 2F are the 2F's larger bore, the F's 2 compression and 2 oil rings versus the 2F's 2 compression and single oil ring and the fact that the F had two oil paths--through the filter or through the engine compared to the 2F where all oil had to travel through the filter before the engine.
