Just picked up a V8 engine to put in the Red Shed :D
As far as I can tell from the engine number its from an SD1 from 1979/80 from an auto. Also stamped on the head is 9.35-1 , is this a higher compression version and will it be suitable for a S3 :?:
Cheers

yes and yes nice engine get a bit more power

The last of the P6's had the highest CR at 10:1, but it would only run on 4 star with the timing retarded to TDC. It was designed for 5 star fuel. Had one, been there, done that! But, even then, it went like stink.
Had a couple of SD1's prior to the P6 and they were nowhere near as quick. But I would still quite like a Vitesse though :D

Few jobs to do on it - like a total stripdown to see what needs replacing.
Can the Series 3 clutch plate be used or does it need to be RRC :?:

Make sure the gearbox spigot bearing is suitable for a manual box. Some standard SD1 auto V8s have a steel spigot bush that fits but welds itself to the mainshaft after a little use.

Not sure what spigot bearing is in it - but the engine came out of a 2A Hybrid.

Its the bush up inside the end of the crankshaft in the middle of the flywheel, and supports ths spigot on the end of the gearbox inputshaft. If its already been used with a manual box in the 2A it should be ok.

You can treat unleaded to get well over 100 octane quite cost effectively, or run on LPG with an octane rating of about 115.
All the RRC autos i've seen had the same crank as the manual, but you have to fit the spigot bearing.

But we were talking about an SD1 V8, and I know that at least some SD1 V8 autos used a steel spigot bush the same size as a series spigot. It must be changed for a bronze bush or it will weld itself together due to the rotational friction when the clutch is depressed. Then try removing the gearbox!!!

Is the SD1 auto different to the Range Rover auto then?
Mine was from an 87 ish Rangy auto and there was no spigot bush at all in it. The manual bronze bush just pressed in to the crank.

Yes they used a different gearbox which had the same size spigot as a series manual box. Hence the problem, folk would drop an SD1 V8 in to a series three and not bother to change the spigot bush as it was the same size. Trouble is Rover fitted a steel bush. As there is no rotation between the crankshaft and the spigot of a torque converter it was fine. With a manual box everytime you put your foot on the clutch there is rotational differences between the spigot on the mainshaft and the crankshaft. If you are lucky it seizes and breaks the spigot off. Now that may sound bad enough, but at least you can still separate the engine from the gearbox. Some however don't break but the heat welds the two together. Now try separating the engine and gearbox!!!!!
It is very easy to remove the spigot bush bye the way. Just fill it with grease, find a piece of rod (old bolt) the same size as the spigot, thack it into the grease, hydraulic action forces the bush out. Or you get covered in grease if you used too small a bolt :-)

Well, you learn something new every day here :lol:
I'm assuming the lack of bush in mine is because the torque converter supported the shaft so it doesn't need one.
Edit: Cancel that!!! Just figured it out. The spigot on the front of the shaft must be larger on the RR gearbox.
