I guess there is no arguing that an ally sump on a vehicle of minimal ground clearance seems like a less than ideal design, and perhaps less so in the age of sleeping policemen etc..? I have hit the sump on my +8 only once that I can remember when going through the gated entrance of a petite chateau while touring. I guess I was too busy looking at the interesting architecture to note the ruts either side of the cast iron centre gate keeper which hit the sump with a clunk...Ouch..! Had the sump been alloy I would have been stuck in France for a while.

Having spent rather a lot of time over a period of circa 25 years reading of the many and varied ideas on modifications, I have seen a few folk setting out to make "improvements" to their Morgans, that created ..err..side effects they had not exactly considered,. but then has that not ever been the way..? I remember one who fitted a rather stout crossbar to protect the sump of the taller modern engine he had fitted in search of more power and reliability and which unfortunately reduced his sumps ground clearance... I think he sold it on soon after.. Of course I have also noted some well engineered solutions which have been created by skilled Morganeers, though Ido wonder at the number of potentially dangerous mods carried out and how any might affect any resultant insurance claim..?
