It's not difficult to make a Minor go faster. 
It's more difficult to make it stop faster!

If you put a more powerful engine in a Minor, you should really upgrade the
brakes as well. Your insurance co. might take a dim view of an accident
claim if you don't!  The Morris Minor Centre in Bath used to do a brake 
upgrade for their so-called 'Series three' Minor. To make best use of the 
bigger engine requires a different diff. If memory serves me right, Series 
II minor was 4.55:1 (41:9); minor 1000 was 4.22:1 (38:9), spridget was 
about 3.7 or 3.8:1 (34:9, 33:9?) , but they had smaller wheels.

The swap of gearbox/engine depends on a couple of things. Series II Minors 
had a smaller clutch than the 1098cc Thousand, and the gearbox bell housing
doesn't quite clear the larger clutch cover plate. Judicious application of
abrasive materials will cure the problem. The flywheel is slightly 
different too, so small clutch and big engine aren't compatible.

Also, the Series II gearbox has no remote control, so the gear lever comes 
through the floor in a different place. 

I read some ancient magazine articles that claimed only minor (!) 
differences (except power and ratios) between sprite/midget/minor
engines/gearboxes/differentials/halfshafts etc etc. 

I have an official British Leyland (who?) workshop manual covering the 
Minor MM, II and 1000 if anyone needs info.
