If it wasn't for the informed comments about carbs, my first instinct would be to wonder which diff has been incorporated beneath the special. Duncan reports using first gear, now my Ruby despite being many hundredweight heavier than any sporting special only ever needs first for going up double chevron hills laden with passengers or a very big picnic. The special benefitting from accelerating in first, but then not getting above fiftyish in top almost sounds like a perfectly set up trials car. Duncan, it seems highly unlikely that you found an Andy Bird trialling gearbox by chance, but are you certain which ratio diff you have used?
