Rolls Royce B60/B61 & B80/B81
Alex
and B61 is? I'm presuming the difference is the same for the B80/B81
(and B40 as well, I suppose)

Not exactly, but it's some random combination of mountings, which way
up the block is, how the cooling works, and the fuel system. Although
the 4/6/8 is the number of pots, the rest seems to be sequentially
issued, rather than having a logical meaning.
It's at the level where a B81/2 won't replace a B81/3 (and you then
have a large and expensive piece of useless junk sat in your shed next
to your broken Saracen)

heard running. What was B61 used in?

B61 was an aluminium block & head version of the B60 for the VP 4 Litre R
The B81 which was mainly used in Dennis fire engines I think was of bigger
capacity than the B80, I presume it was also alloy block.
I don't think the B41 was ever built but knowing the british military mind
perhaps a B41 powered Champ or Series 1 Landy is still lying is some coldwar
bunker somewhere.

manual gearbox to go on it. Pref a straight bolt on job. Any ideas?

Ahh, so I really have a B61(actually 2) :-) What I would really like is a
manual gearbox to go on it. Pref a straight bolt on job. Any ideas?

I don't know, as the Alvis and the Daimler had Wilson Pre-Selector
Transmission. For a manual box you would have to look to a Bentley, or
a Rolls. The Bentley Mark VI and the Silver Wraith both had manual
transmission, pre 1952. Wether this would fit onto your engine I do
not know, as the B series engines seemed to vary considerably during
thier life, even to the extent of being made in three sizes, 4257cc in
the Mark VI, increasing to 4566cc in 1954, and 4887cc for the
Continental and R-Type in 1954. They were also available in different
compression ratios. The 4887cc engine went on into the Bentley S1 and
Rolls Silver Cloud, but were (nearly) always fitted with Hydromatic
transmission in these cars. The B series engines started off in the
Mark V in 1946, and was only withdrawn in 1959, with the introduction
of the 6230cc v8 in the Silver Cloud II/S2. Not bad, for a pre-war
engine design, originally built in 1939 (war stopped production)
Believe it or not, there was a make of cars for which the IOE engine
design lasted longer. Landrover fitted a 1600, 4-cylinder engine to
the first Series 1's in 1948, although the engine had been around
before. It was upped to 2 litre, and six cylinder versions were
avaialble in 2.6 and 3.0 in the Rover saloons. The 2.6 was used in the
Landrover up untill 1980, when it was superceeded by the 3.5 v8.

I believe The Mahindra Jeep is still avialable with a the Willys IOE
engine in its home land.

I'm understand that these boxes would fit but with the price being so huge
it just wouldn't be an option. I think capacity changes were just bore and
stroke changes, block stayed the same so presumably boxes were
interchangable. A pre-selecter would be great. But again, huge cost. I was
hoping(cluching at straws really) for someone to pop up and say a Champ box
would fit but even if it did I doubt it would take the power. Realisticaly,
I think it will be staying auto. But I live in hope :-)
Thanks

Realisticaly,

Champ box would take the power but it has no reverse gear.

I assume then that reverse on a Champ is in the transfer box. As I heard it
the reverse was just an idler gear running in a plain bearing, allowing the
Champ to reverse in all four gears(but not for long :-)).
Thanks for info.

All five gears.

All ten gears possibly? I'm not 100% sure but I believe that the
Daimler Ferret had a two speed transfer and a reverse, meaning you
could reverse in 10 gears. Certainly I can use 3 reverse gears in my
Landrover, thanks to a xfer and overdrive.

Absolutley not an expert, but I used a Daimler Dingo as my wedding car in
1969. Went just as fast forwards as it did backwards. I think it had a
pre-selector gearbox, although memory is hazy. Same number of gears in
each direction.
Frightened the hell out of the Vicar when I arrived at the Church. Still
had full armament, which gave a whole new concept to the "shotgun wedding".

Daimler (Wilson) 5 speed Preslector, no reverse, Fluid Flywheel
coupling. Reverse in Transfer box.
