Engine capacity of bus on ebay item 310075278377

IIRC all the 75s were sixes. And it was a very smooth engine with bags of low speed torque. But as you say, heavy on fuel - like all IOE designs.

I've not actually had any experience of a P4 four cylinder model - but have read they are rather agricultural. Which is what surprised me about your post.

My old P6 3500S would start in top pretty easily on the level. And run down to just over walking pace without judder. After I'd removed those damn poppet valves on the butterflies.

The message from Grimly Curmudgeon contains these words:

According to an article in the October 1994 edition of Classic Cars the P4 75 was fitted with the same 2103cc IOEV engine that had powered the P3 75 when introduced in 1949 although it is not clear whether the aluminium cylinder head was a new element. The cyclops grill only lasted until 1951. ("Rover wanted to make vehicles which pass unobtrusively and are not noticed").

The 4 cylinder 60 (1997cc) and the 6 cylinder 90 (2638) did not arrive till 1953.

In 1959 or 1960 there was a major overhaul of the range losing the 60,

ISTR 'Autocar' used to pull a similar trick with any V12 Jaguars they had on test.

No, only S3 military, S3 1-tonne and late Series 3 109/Stage1 V8's had Salisbury, 1-tonne IIA and Early Military had ENV diffs. The Salisbury have 24-spline halfshafts IIRC which are much less prone to fractures as they don't have the same stress radius as the 10-spline ones. As for the O/D I think using it in anything other than 3rd/4th would be a very bad idea.

It was orignally 7:1, raised to 8:1 about 1967 (in the Landrover, possibly earlier in the Rover) It is perfectly possible to raise to

A mate said he watched an Rover V8 powered Imp race at Castle Combe in his younger days and that was kept in 4th to protect the box and once on the move didn't need gears because of the engine torque.

Ta. Thinking about it, I've got through five 109s over the last couple of years, all of which would have fitted into the above categories, hence my assumption. (Stage 1 V8; 6-cyl 1 tonne; Ex-military; Ex-airfield fire tender; 1 tonne)

Agreed. I'm trying very hard to get into the automatic habit of dropping out of O/D as I slow down and checking before starting off, but I know it's only a matter of time before I forget!

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Alex saying something like:

Pretty much as I suspected. It would be nice to take a later 5-main and tune the bugger, but rather pointless in a way. Mind you, even at say,

Almost a hundred years ago a Silver Ghost Rolls-Royce was driven from London to Edinburgh using top gear only. This was the 3 speed model, the factory having stopped providing an overdrive 4th gear as they weren't satisfied that their customers were capable of using it properly/
