I had one in a 109 years ago. I suspect it was originally a
plant engine... It did 38 mph flat out but pulled anything, I
liked it ! :toothless:

4203 in a Landy ,yuk,yuk yuk. Great engine,not for today. Slow ,
smokey , primitive , enough torque to rip things to bits if not
carefully used. To get it right there is a domestic type but
it's rare and you will have spend on gearing. >vom<

My first Landy had one. A great beastie it was too.
It was an ex 6cyl 2a LWB Safari, so had the larger engine bay,
huge front brakes and a Salibury back axle, it did eat gearboxes
though. This wa why I had too much practice swapping bell
housings as I need the half past the hour stud holes for the IOE
engines.
I used to swear if it fell off a cliff it would reach terminal
velocity of 67mph!
Because of the 6cyl engine bay I had to cut a chunk out of the
bulkhead to get the head off when it hydraulicked on cyl4.
Finally it started spewing oil out of the crank case breather,
so I replaced it with a rover V8. I swear the the head of the
smirkins weighed as much as a V8!
The only things apart from lack of revs that annoyed me were
constantly having to replace combustion chamber gaskets which
blew regularly and the fecking exhaust manifold. The slightest
bit of offroading and either the downpipe would crack on the
cross pipe or the front joint on the manifold would crack. It
had basically two 6" pipes straight out from the two exhaust
ports cut at 45degrees with a cross pipe welded between. (Yes
cyls1&2 exited one port and 3&3 into the second port)
I sold the engine to Steve Parker in Doncaster, he found that
actually the problem was the vacuum pump (I had a S11 with servo
brakes) was pressurising the crank case thand the engine was
fine. But hey by then I could accelerate and hit 90mph, more
importantly I could RTV in an ALRC event as it was a rover
engine :smile1) so didn't miss it.
Then I bought a '72 Range Rover with a D4.236 in it :banghead

Perkins V8 eh :thumbs: I believe they did a straight Six
version of the 4203 ( 6203 ? ) too, I have vague memories of
such a thing gashed into a series 3 at a show somewhere years
ago....

"I used to swear if it fell off a cliff it would reach terminal
velocity of 67mph!"
Megatoad, your Perkins lump hasn't actually slowed it down as
much as you might think...... ;D
Assume:
- weight of standard LWB Series 2A in running condition is, say,
1700 kg,
- dimensions L 4.44m, W 1.68m,
- it is roughly brick shaped
- it maintains an upright position during its fall off the cliff
then according to www.calctool.org/CALC/eng/aerospace/terminal
the terminal velocity of a standard LWB Series 2A is 37.8 m/s or
84 mph!
Of course, 1960's vehicles are most often seen falling off
cliffs when driven by baddies in British films and TV programmes
of the period. However, they rarely reach terminal velocity
unscathed because they unaccountably explode in a fireball
halfway down.

There was a 6 cyl a 6.354. Later turboed.
Eddy Smith from Miiddleton put one in his LR,it would set off in
o/d top.
He could break rear half shafts at will,especially up Cromford
Hill , Matlock.
This engine was common in many trucks ,Commers,Dodges,Dennises
etc. drink(*&

.... and that is the reason why most commoners and non land
rover lovers who owned a series locally would simply go "land
rovers are just shite not worth having, too much gearbox
trouble and halfshaft problems" ... hence the sudden demise in
interest in such a great car :(
... the perkins was very popular conversion here since most
series that were imported where petrol powered 2.25s. The sudden
rise in petrol prices back in the 70s gave rise to an alarming
massacre of 2.25 petrol burners due to using kerosene in them
(and then the yanks go boast they have a multifueled hummer
:eek:)
the perkins 4203 was the engine of choice when they wanted to
shift out of the petrol motors. they didnt even consider 2.25 or
early 2.5
