I would suggest that this vehicle was first a petrol Land Rover. It has a petrol dash, petrol starter button, petrol choke (with choke light switch, choke most likely being used as pull stop) and the glow plug resistor is in the wrong spot. It has a six cylinder grille. I had not heard of, nor seen this grille on diesel vehicles, though I am open to the idea. Judging by the injectors, this is a late SIIA or SIII 2.25 diesel engine. To confirm the original specification, I would like to know the chasis and engine numbers.
Does the exhaust exit the manifold sideways or downwards? It appears in the picture to exit downwards, which would suggest a SIII engine (exhaust manifold anyway).
With regard to price, does the engine run? Does it stop smoking soon after starting? I recently saw a second hand 2.25 diesel engine (engine only) sell for over $1000 on E-Bay. Diesel engines are slower, but are more efficient, have more torque at lower revolutions, and are rarer. Do you specifically want a diesel?
Aaron.
