Through necessity - it cracked a piston.
After carefully stripping and reassembling, it started first time smile .
The ecstasy quickly turned to agony when I realised the oil pressure light wasn't going out frown .
To cut a long story short I didn't fill the new oil pump before fitting it (must've missed that in the Haynes), so is there a way of rectifying this without pulling the engine and stripping it down again?
I have been told taking the filter off and pumping oil into the little hole from my Wesco can, while pushing the car backwards (while in fourth gear) will draw oil back into the pump - I've tried this for half an hour this evening and managed to dribble a trail of oil in the street. Does this really work - should I persevere tomorrow with this?
Cheers.

About £600 for machining and bearings/gaskets.
I already had an SW5i kit (cam, duplex, valve springs, oil pump), clutch, pistons and bits and pieces for my kit car engine when the mini piston went pop. So probably £850-ish.
Just remember to learn from my lesson and fill the oil pump before fitting, or you'll be looking for the same answer!

Mike,
The hole I've been trying to pump oil into is the small one adjacent to the threaded oil filter hole in the centre. My car is an mpi, so the hole is at approx. 7 o-clock to the centre threaded hole.

Thinking about it, I did put the O-ring in place between the gearbox and block.
But when I fitted the gasket (having three gaskets for this location did through me at bit at first!) I did notice the hole at this location was smaller than the diameter of the O-ring. That is - the O-ring will be being compressed between the bottom of the recess and the underside of the gasket. Could this be causing the problem?

Ended up pulling the engine, filling the pump and refitting.
Engine got oil pressure, runs nicely (with only a slightly gruffer idle - SW5i fitted). Can't wait to drive it!
But I'll have to - the water pump gasket is leaking! Oh well....
Still chuffed that it works, and sounds great.
