Ok, having finally gotten fed up of Petro running like a bag of nails (he's also developed a big end knock, and I never did quite get to the bottom of that overheating problem) I've decided to give up with the current engine and swap it out...
I have aquired a Series3 lightweight for this purpose.  The question is are there any differences or problems in putting a series 3 engine into a two.
1.  I know that there are some differences regarding the clutch mouting, but I seem to recall those being mention with regards to putting the three box in, which I'm tempted to not bother doing as the series2 boxes are stronger, does anyone have a definitive opinion / experience on this ?
2.   Assuming there are no real differences between 2 1/4 petrol engines (early to later) is there anything stupid that I'm forgetting ?
3.   I'm also assuming that swapping the overdrive over would be a reasonable idea as well.
4.   Does anyone know how I can get Col to expediate his tidy-up of the garage and then give me a hand :)
Any thoughts?  Suiggestions?  Advise....
