People say that a 1098 engine will not cope with a 3.7 diff. You need a 3.9.
Good luck with your search.

I would agree with that. I had a 3.7 combined with a 1275cc Midget engine many years ago and it was somewhat overgeared. Of course your wheel and tyre size will also make a difference. I had 4.5 inch x 14 wheels fitted with 165 section tyres at the time.
If you can find one, a 3.9:1 (MG Midget) will indeed be a better option but there is no point in over gearing the car.
