Whats a Jaguar E-type 3.8 engine complete worth ?
Discussion
Mk10 had 3 carbs.
very easy to put 3 carbs on an "ordinary" 3.8.
No big difference anyway - the so-called straight port head fitted to the E Type etc wasn't massively better that the squiggle port. Especially after being gas flowed. From the factory, the E Type heads were painted gold - but that too is easy to fake.

As V8 says, Mk10s and also 420G had the triple carbs. Before them the XK150S had triple carbs too.
That would be the most valuable engine.
You can look up the engine/head numbers on http://www.jag-lovers.org/xk-lovers/library/engine...
If you want to be really sure then there was a series of details discussions on the different casting numbers used in the XK forum on Jag-Lovers earlier this year. They'd be harder to fake and are much less well know.

E type triples have differnet manifolds and sit lower and manual choke.
Mk10 triples have auto choke and higher manifolds.
That engine is worth about £750 to £1000.
If the carbs are E type then they are £1000.
If the carbs are mk10 then about £200 to £300.
Might bwe a little out of date with those prices.

Its been dropped into a MK2 340 man..
condidition as is .. not been on the road 10 years so ready for a rebuild I guess, the triple carbs had me excited, but I guess then its a MK10 motor or just X3 carb installation...
cheers

The major difference between the MK X and the E Type carbs is that the MK X had an auto choke unit, whereas the E was manual, making the carbs quite different on the bottom sections. The engine in the photo has an auto choke setup. They also ran different needles as the air filter and compression ratio was different between the 2 cars. If you look at the cylinder head immediately in front of the first spark plug you will see the engine number that ends with a /8 or/9. That tells you the compression ratio.condidition as is .. not been on the road 10 years so ready for a rebuild I guess, the triple carbs had me excited, but I guess then its a MK10 motor or just X3 carb installation...

The 3 carb manifold will not fit an ordinary MK2 head, it has to be straight port. However if the car is a 340 as opposed to a 3.4 MK2, it will have a straight port head anyway. It could have had a complete engine change, in which case it would be a 4.2. If you look underneath the carbs on the same side of the block it will tell you the engine size.
The engine in the pics is running pancake filters, so the carbs will have to have different needles fitted if not already done so.

If it's a 340 that had the straight port head so it could be the original engine. As Huntsman says, the E-type inlet curls down to keep a lower bonnet line. The Mk10 manifold keeps the carb centres at the same height as the inlet ports.
Its not easy to tell from the photo but I think the manifold looks more like the 4.2 one (which I think would be the easy one to fit to a 340's head) rather than the 3.8 one.
The 3.8's inlet manifold is in three pieces with a water pipe across the top.
This is a 3.8 E-Type manifold I bought by mistake, I needed a Mk10 one, the E-Type one fouls the steering column on a RHD XK150.
This is a 4.2 Mk10 manifold with triple carbs on my XK150
Sorry my posting coincided with Jith's if there's any disagreement, I'm probably wrong

I trump your 3.8 with a 5.3....................
Yes, I know I've posted it before but I still like it! Incidentally E-type 3.8 engines were numbered from R1001 upwards. I forget without looking up the numbering for the other models. Mine is R1798-9 for example, indicating, like most cars, 9:1 compression.
Oh, and before I forget, 3.8 E-type engines are getting rare and prices are going up.
