This 1300 (the '72 was a 1300cc engine, 1500's start in 1973) is the worst of
any Spitfire in terms of power.

Goes right in, no problem!

May need to change the throwout bearing, arm, etc. to the 1500 setup.  Check
them visually, it depends on the clutches.  If your 1147 is really a MkII,
this probably won't be neccesary, but maybe better safe than sorry.  I think
the slave is the same.

Don't bother

If you use the 1500 transmission, the rear flange bolt pattern is larger, so
your driveshaft won't bolt up.
