I'm sure the weslake head could have had a modified inlet manifold to give appropriate clearance on the RHD steering. (Yes there are people who have put weslake heads in Land Rovers but ask scouse how close it is?)

Diana,
A guy I work with runs a Rover 3litre and would like to fit a 3litre to a Land Rover at some point. He did mention that the crank was different for the auto so you'd have to find a manual 3 litre Rover which are a bit scarce (most were sold as autos).
It's on his 'to do' list.

where on earth would 1 find a 3l motor now? be easier to find rocking horse wouldnt it? :D
Cheers Scott

Glum,,, I have a 3 litre ------ auto engine !! :(

That is always the way isnt it? When you want something like that it is always just a bit wrong! Never is it easy! :D An auto 3l 2a perhaps? :D
I am having enough problems finding a fair to middingly 2.6 6cyl ;)

Is there a picture anywhere of a Westlake head and carby setup?
I don't know much about them.

The crank on the automatic 3 litre engine is an 8 bolt crank where the Land Rover 2.6 litre is a 6 bolt crank. However the flywheel for the 2 1/4 litre Land Rover engine is the same 8 bolt PCD as the 3 litre auto engine.

The problem is that the 2 1/4 flywheel is a tight fit inside the 2.6 flywheel housing/engine adapter. I had planned to check if the 3 litre engine adapter would fit a 4 cyl bell housing but that is on the to do list. (One of my engines came without a flywheel housing.)

What I am currently doing is modifying the 2.6 engine adapter to accept the larger PCD of the 4 cyl bellhousing by machining out the inside of the housing and building up weld where the repositioned studs need to go. (This is for a proposed short bellhousing Defender 5 speed R380/LT230 conversion, the vehicle has already been converted to CV front end.)

I believe the 3 litre manual engines (very few and far between) are 6 bolt cranks. (BTW: the Borg & Beck clutch pressure plate for the manual 3 litre is a 10" version that bolts directly onto a Holden 253 and 308 V8, it's what I used on my SIIa conversion in 1975)

As opposed to the regular Land Rover six with its integral head and inlet manifold, the Weslake head is very much like every other engine, a head with a bolt on inlet manifold. The difference is that instead of a downdraught carby the inlet manifold has an SU mounted horizontally mid engine causing a problem with RHD steering boxes. The LHD don't suffer the same problem hence why the NAS Land Rover SIIa 6 cyl has a 2.6 litre Weslake head engine.

You could always fit a Land Rover head to a 3 litre block, so long as you also fitted the Land Rover waterpump and adapter plate.

Why? I have a Mk1 and a MkII 3 litre engines.

The ideal thing to find would be a MKIII suffix C 3 litre crank, conrods and pistons +/- the cam and you can make your Land Rover 2.6 into a 3 litre. The 2.6 and 3 litre having the same bore and the Land Rover bock is the same as the 3 litre block.

You can't use the earlier suffix 3 litre cranks as the main bearings are smaller (the same size mains as the 2.6 litre in the Land Rover SIIA and SIIB forward controls).

Diana

Wow! Thanks for all that info :) I have never had much to do with 6cyl landies let alone ever seen a 3l apart from at car shows and never around where I am. Nearly all Landies here are 4cyl LWB and SWB or if they had a 6 it was a holden! The 2a S/Wagon I have aquired was a 2.6 and I am sorta looking at replacing the holden with a 2.6, just for originality sakes. Much learning and looking to go I think :)

Cheers Scott

I love originality, but the standard 2.6 just doesn't do it for me and hence why I've two 3 litre engines to go in where 2.6 are coming out.

Last december whilst in Canberra saw a commercial property in Fishwyk full of old rover cars (non goers by look of them) possible engine or diff source, somebody may know more details?

I know there is a couple of 3 litre 6s here

22°45'29.22"S 135°44'59.12"E

217.5 KM North East of Alice Springs

It was at least 15 years since I was there but there was a couple of them there.
