Hello,

I'm new to this group and I hope the Jag experts here can help me!  I
live in the US and have a 69 series 1 rhd car with a 2.8 litre engine
and a manual/overdrive transmission.  This car has manual windows and
does not have A/C.  The engine is incomplete and seized.  I won't
consider repairing it because of design problems.

I would like use the original 3.4 (not the SII XJ engine).  I don't
need a lot of power and a 2.4 even crossed my mind but they are scarce
here and the XJ is too heavy - though mine is about as light as they
come!

Are there any serious incompatibility problems with this swap?  A
different bell housing and clutch would be required as the 2.8 has a
short deck and the starter position differs slightly from other XK
engines I've seen.  Does the 3.4 have the same deck height as the 4.2?
Is the bell housing pattern the same as a 4.2?   Can I use 4.2 clutch
parts on the 3.4?  If I must use a 3.4 bell housing will my
transmission bolt up to it.  

Any help is appreciated!

Bob
