Hi, will my 1961 Morris Minor 948cc run ok with a SU HIF44 carb on it.
Thanks, Bernard.

It will run, but I doubt it would be great - that carb is too large. If you want to go for a larger carb than standard, I would think a HIF 38 would be more than enough on a standard 948. That's what I have on a quite well-modded 948, and it's plenty on that too. Even that isn't going to give much benefit without other improvements to the breathing (exhaust, head etc.).

The largest carb that can be run on a 948cc Minor with standard head and still perform 'reasonably' well is either a SU H4 or a SU HS4.
There is a lot that can be done to a SU H2 or SU HS2 carb to make it more efficient before going to a larger carb.
For details of SU carb improvements see Clive Trickey's book More Mini Tuning published by Speedsport ISBN 85113 000 3.

Yes, can't make a silk purse from a sow's ear. The car can only do so much in semi original form.
