I am after a 6 cyl. LR motor that runs. Prefer close to Melbourne if possible.

Is this for a SIII Army or for something else? ?

Thanks m-coffey, but I think transport would be enormous.

They are not the same as the regular Land Rover engine. 

The f/c version has smaller big ends and mains plus the water pump is the same as the 3 litre Rover car engine.  The f/c exhaust manifold also exits horizontally to the rear between cyl 3 and 4. This is likely an artefact of the f/c being the first Land Rover six and they never upgraded to the later mods, although the Land Rover version would probably be better for cooling.

Hello Diana
I have 2 sixes, one I am going to see if I can fire it up after a lengthy pre start. The 2 have been sitting on blocks for 35 yrs. Both have deteriorated and butchered. I have to admit one will be not quite original and the other for panels etc.
Thanks again many times for your input.

Hi Diana

Not knowing anything about FCs....

would the standard Rover 6 fit into the engine bay without modification to either the motor or bodywork

or

the differences you list ensure that only the early 6 is suitable?

Hi Stuart

The normal control engine would fit without modifying the chassis, but you need the FC manifold or you have to cut one of the upper chassis components to make room for the exhaust pipe.  You will also have to adapt the boss on the waterpump to drive the radiator fan prop shaft.

Being pragmatic, I would remove the prop shaft and use a decent electric fan on the radiator.  This will make a fan belt change a quick job instead of a marathon removing the prop shaft from the water pump boss.  But it also depends on how original you want to be.

The other issue is the gearbox, the FC and normal control boxes actually use the same aluminium cases so can be swapped.  Most surviving F/C in australia that still use a series box use a bonneted control box.

Thanks for the info Diana :)

From the photo below I can see the difference in the FC exhaust manifold and pipe. I can also see the empty space where the radiator fan would normally sit.

What do you mean by a bonneted control box?

Hello  Tommy
No one has answered your question. A Forward Control is a cab over much like a flat nosed truck. A Bonneted Control is just like our normal 109 & 88 etc. where the bonnet is in its usual location.
Hope that helps.

Hi Tommy

I overlooked this post.  In the image, it appears to be missing the pulley on the water pump.  As opposed to most Land Rovers the F/C has a heavy, cast, quite long cylindrical pulley that is a press fit onto the water pump shaft.  The flat end of this pulley is the same size as as the round flange of the prop shaft and is drilled and tapped to accept the prop shaft bolts. 

On a usual Land Rover 6cyl, there is 1" adapter plate to change from the 3 litre style water pump to the Land Rover pump, this pushes the pump 1" forward and the F/C pulley won't fit (it may also make the prop shaft too long, but I havent fitted one up to test.)  You can't fit the 3 litre waterpump and F/C pulley to a normal Land Rover 6 cyl without also changing the head because the coolant bypass ports are in different places.

Bonneted control
In some of the OEM Land Rover manuals and handbooks they refer to the majority of Land Rovers as bonneted control to differentiate them from forward control Land Rovers.  It makes it hard when Rover Co used the term regular to describe the 88" when they described the 109" as  long i.e. Regular and Long models.

In short the term bonneted control would be normal control in the parlance of other truck manufacturers.

Is it possible to use 6 cyl. water pump without spacer on FC 6 cyl and have bypass port line up.

Different shape different number of bolts. (The spacer I mentioned should more correctly be termed an adapter.)

However the normal control Land Rover waterpump has more vanes and is probably more efficient than the 3litre/F-C pump.  Also the 3litre pumps are now made of unobtainium so you are better off with the normal control type on most aspects apart from the interface with the prop shaft.  and for that you can likely get an adapter plate made.

However I am seriously considering using a Holden Commodore electric puller fan mounted in the radiator shroud.  That way it's easier to change V belts and reduces the noise of the fan drive.

It is almost impossible for a casual observer to see if the OEM prop shaft/uni-joints/bearing block is present if originality is important.

About 10 years ago I modified an Oka by removing the engine driven fan and fitting a Commodore shroud and fan assembly. Worked a treat. ???
