Hello all

I am looking everywhere and finally I came to your forum

I have an engine removed from Land Rover Disvocery II (supposedly 4.0 V8)
which has nowhere else the designation S77D (00000A).

You can help me with this engine

I saw that the Morgan company had the engine with the initial designation "S"

I feel confused ... and I am looking for help.

best regards
Grzegorz

 

That is a bit mysterious. It doesn't appear on this chart.

I know, I have searched all google and there is no information about this engine and I have it in stock

 

What do you need to know about it?
4.0 and 4.6 look the same, and are basically the same other than the crankshaft and rods/stroke.
The pistons have a different shaped top, and I think a slight difference in compression ratios, but their diameters are the same in both engines.
The heads with be SAI(2 brass tubes per head between spark plugs), or non SAI.
A Gems engine has the black upper intake, the other is bare aluminum.
If you are rebuilding the bottom end and need parts, it's easy to measure the stroke after disassembling the engine.

 

I will not disassemble the engine. The point is that I was very interested in the fact that I have a mark on it that is not in any catalog.

 

I have a company that sells engines and I wanted to unambiguously without stripping it, and after marking the engine, confirm if it's 4.0 or 4.6. I no longer have data from the car. Apparently it will be 4.0 V8

It also has CR9.35: 1

This is exactly the engine:

the rocker cover on one side has the smaller aperture of the 2003-2004 engine, which i think would make it most likely to be 4.6L unless that part has been replaced.
there are some differences in the oil pump/timing chain cover between the early and late engines too; one has an open port for an oil cooler but again, those parts may have been changed during the operating life of the engine.
it is definitely not an sai engine. at least in the u.s., non-sai engines were rare after 2002.

 

A picture is worth a thousand words.

 

you mean like the pictures in the link that was posted?

 

The link came up blank for me.
